Title: Voigtlander 125mm f/2.5 APO Lanthar
Post by: Jan Anne on June 10, 2015, 16:44:19
The lens that Cosina needed to stop making to land the Zeiss contract and became legendary afterwards because a certain Norwegian nature photographer declared it as one of the best lenses ever made (and from personal experience can tell you he still uses his on a regular basis if not daily).

I was lucky to source one locally with a Canon EF mount new in box for a very decent price last year and am very pleased with it on the Sony a7S.

Here's a mugshot on an a7R (which got traded for the a7S) using a Commlite EF-NEX electronic adapter, the electronic adapter enables the operation of the aperture (sadly no aperture ring on the EF model), EXIF registration (though f/2.5 registers as f/2.8 ) and on modern Canon lenses also the use of AF and IS.

Update 11-3-16: The EXIF registers properly now with a Metabones IV T adapter.

I didn't use this lens that much but here are a few images, don't hesitate to add more samples to this topic.

If anyone should be in doubt about the image qualities of the Voigtländer 125 mm f/2.5 APO-Lanthar lens, these images should settle the score once and for all.

A fantastic lens that delivers both in technical quality (detail, free of aberrations) as well as aesthetic capabilities (pleasant rendering of OoF areas). Bought mine in December 2009, used in a box for 900 EUR. I sincerely can't see why anyone would sell this lens, it is every bit as good as the reviews written about it.

I am aware of the internal construction which makes it prone to loosening and disassembling itself, this was however in my case quite easy to prevent by having a local technician open it and replace the screws, it has worked flawlessly for the past 6 years and I have actively used it for shooting watches and jewellery for clients.

I'm lucky in having my close friend Erik making the maintenance service and repair on the 125 APO-Lanthar each time I visit him in Copenhagen ... The first of my 125 APO-Lanthars is around 10 years old now and as laconically remarked by Jan Anne, it looks "used" ....

Since I felt uncertain how long the lens actually would hold up and for how long Erik would be willing to do the internal work on it (well, mainly the first was of concern), I got another sample to distribute the wear. A Lanthar version of the SSD "wear-levelling algorithm" so to speak :D

I have the two other models in the Lanthar series, thus the 90 mm f/3.5 and the 180 mm f/4, and whilst they are excellent lenses on their own, somehow they don't shine in their performance as the 125.

I'm using the 125 mainly for landscapes and details. Visible light applications only, as it like so many fast lenses, exhibit a hot spot in IR. Nor does its fare well for UV, but no worries as I have UV specialist lenses for that purpose.

My 125 APO-Lanthar lenses are both CPU-modified of course. Erik to the rescue again (modification of this lens is non-trivial in case anyone wonders, but not enough to deter Erik ...).

The image smoothness delivered by the 125 is remarkable and colour clarity is outstanding. The latter no doubt is due to the near-perfect "APO" behaviour of this optical design and the main reason I quickly got rid of my AFS Micro-Nikkor 105 mm f/2.8 VR and replaced it with the 125 APO-Lanthar.

There is definitely something in the clarity and purity of color rendition on this lens - the spidercrab photo is an excellent photo and it also displays this. High contrast compositions without lateral or longitudinal color fringing --> don't we all wish for that in a lens?

I never doubted the quality of images the lens can make in the hands of good photographers  :D .  I tried my hardest to find one at a reasonable price but last year I was only looking at a Nikon mount.   I remarked at the time than the prices for Canon and Pentax mounts were quite reasonable.  Now that I am shooting a Sony a7II even those are getting hard to find and more expensive.

 Bjørn , problem is, lots of guys are just like me and shoot Nikon and other brands and have read your views.  So , I'm with J.A. , it is your fault  ;D , ;)

Great of you and Vilhelm to rub it in with more superb examples....  ;D J.A., first Blackberry I've seen in a couple of years  :)

Yes, the Zeiss 100/2 has shockingly bad---considering the price of the lens--- axial color.  I have shots at f/5.6 that clearly show it.  Very annoying.

Lens: Voigtlander 125mm f/2.5 Macro APO-Lanthar
Focal Length: 125mm
Widest Aperture: f/2.5
Narrowest Aperture: 22
Aperture Blades: 9
Filter Size: 58mm
Hood: Included, Square
Close Focus Distance: 14.96 inches (38 centimeters)
Reproduction Ratio: 1:1
Focus Throw: ~ 630º
Weight: 28 ounces (794 grams)
Pros: Very fast lens, very sharp lens, 9 blades, close focus, goes 1:1, long focus throw.
Cons: None. Perhaps a little heavy.

I could write a book about this lens, but I will spare you. Next to the new Zeiss Otus-style lenses, the CV-125 is, hands down, the best macro lens I own and I use it all the time, even though I have a shelf full of some of the best macro lenses in the world at the ready. It has no major negatives. It is very fast, very sharp, focuses close, has a long focus throw, reproduces to 1:1, has 9 blades (great bokeh) – the works. If I want to complain, it is a tad on the heavy side, but I am always happy to carry this piece of glass in the field.

The lens is very difficult to find in the Nikon format and also very expensive, with copies now going for $2500 or so. Despite all the good qualities, probably the features that set this lens apart from other fine macro lenses are the fact that it is truly apochromatic (APO) and has such exceptional bokeh (lovely out-of-focus blur in the background).

Of course, IMO, I would add that it has a “magic” quality that words can’t express and a very-long focus throw that makes macros and stacked-photos so very easy. I find it very stable when it comes to handling various types of light in the same frame, like shade with rays of sunlight. This is real workhorse and I have used mine day in and day out for years.

It focuses to 1:1 and lets you get very close in on your subjects. A feature not often mentioned about this lens is that it is also very sharp at mid-range and even at landscape distances. This is the little lens that could and it does. If you ever find one, buy it. You will never be sorry.


Like Bjørn, I have the 90mm and the 180mm Voigtlander APOs, although I don’t use them much. The 180mm is not a close-up lens, which is one reason it does not get much use.

And yes, I learned about this lens from the Fierce Bear of the North, years ago. Thank you!

Michael, you out-Lanthar me 3 to 2 :D

Despite it being labelled "Macro", and goes all the way to life-size 1:1, the 125 APO is not at its best there, and the otherwise superb apochromatic correction begins to falter.  I use this lens at least as frequently for landscapes as for close-up subjects.

The questionable internal design *will* cause issues for lenses used in the field, so the 125 should be serviced at regular intervals and if one relies on it as a work horse  "always present" in the lens kit, purchase a backup copy the sooner the better.

That's true, but as President Obama said to Hillary Clinton during a debate when she was pining about not being liked, Obama said "Hillary, you are likable enough." I say that even at 1:1, the CV-125 is "likable enough." I tend to use it for close-up, rather than macro, so it is way more than likable enough. What I say about this lens: aside from Zeiss Otus lenses, the CV-125 is the all-around best macro lens I have ever used, meaning I used it all the time. Indeed, IMO, it is a very special lens.

The 90mm and 180mm lenses are not macros, but both focus very close for non-macro lenses - around 1:4 - which is perfectly good for casual closeups.

The 90mm comes with a close-up lens and the 180mm has a minimum focus of almost 4 feet, which is not close enough for work I do.

How would you compare the Lanthar 125mm to the Zeiss 135mm f2 APO? In terms of bokeh, color correction, close and far performance and the maximum magnification you can get with decent results (using extension tubes etc.)
Title: Re: Voigtlander 125mm f/2.5 APO Lanthar
Post by: Bjørn Rørslett on January 18, 2016, 13:27:31
The 135 despite its other virtues would be handicapped in such comparisons. It is a telephoto design and this isn't optimal for added extension. It bears repeating that extension never can improve image quality only degrade it for any ordinary lens. The added "empty" space is devoid of glass which misleads people into thinking nothing harmful happens, but that's far from the truth. The optics are brought into conjugate distances for which they are not designed and this in turn negatively affects image contrast and correction of spherical and chromatic aberration. Telephoto optics are particularly prone to adverse effects by extension. They will also show a larger drop in effective aperture in the near range.

Had the 135 Zeiss been intended for "macro" work, the maker would have given it the ability to focus closer.

Of course a telephoto design would never perform without quality loss with added extensions, but I also read that the Zeiss 135mm is exceptional at  1:4 compared to most competition and may take an extension's optical issues with some grace.  Getting the Zeiss to 1:2 should be easy with a single extension tube maybe a PN-11.

I guess Lanthar 125mm is not "most competition" and it's also a real macro lens.

The Zeiss135mm APO is the better lens than the CV-125 in almost every way, except it was never intended for close-up work, much less macro. It does not take extension well in my experience, but there is this:

It is very, very sharp, despite what the tests and reviews say. Sometimes I feel it is sharper than the Otus 55mm. And it is certainly sharper (and better corrected) than the CV-125.

Here are two shots taken with the Zeiss 135mm APO lens and I believe the Nikon D800E. The first shot is a full-frame shot, the second a crop of the full-frame photo. So, yes, it is not made for close-up, but also yes you can get great close-up photos from it by cropping.

https://www.flickr.com/photos/98006906@N05/9497416896/in/photostream/.

However, unless you want to have a bunch of Otus lenses, like I do, you would be better off with the CV-125 as your regular macro lens. It has all the features that any great macro lens requires and more. It has a “draw” or style to it all its own, one that I happen to really like.

That being said, I seldom use mine. Instead, I bend the new Otus Series (I consider the 135mm Zeiss part of that series) to my will as much as I can and attempt to use them as I would a macro lens. But, that’s just me.

If I would advise you, I would say get the CV-125 and be happy. Remember, that I most often stack focus using very fast lenses wide-open. Therefore the Zeiss Otus are perfect. The CV-125 is not as sharp wide-open, but hey: it is worth (for me anyway) selling a bunch of other lenses to get one. Why? Because you will use it and enjoy using it and love the results.

As for me, part of my photography is pushing the envelope to try to find new techniques that work for me. I do that more (these years) than walk around being a macro photographer, and I don’t like “gotcha!” photography anymore, like sneaking up on bugs. I have been there, done that, and it does not appeal to me. I am happy to look at other’s “gotcha!” photos, and totally understand the appeal. I just have other visions at this point.

So, as the say "Do as I advise you, not as I do." I love my CV-125s and keep reaching for it, but mostly it sits there, looking fine, while I play with all these other also great lenses. But for most work, it is the best.

How would you compare the Lanthar 125mm to the Zeiss 135mm f2 APO? In terms of bokeh, color correction, close and far performance and the maximum magnification you can get with decent results (using extension tubes etc.)

Michael & Bjorn are far more qualified to answer these questions and I only found out and hence purchased these from their expert photographs and comments. Here however is my 2 cents:

The Zeiss IS a technical tour de force. It is very sharp, very well corrected, APO through to the infra red. I think Michael wrote that all the f stops really change is the DOF as it remains sharp and highly corrected even from the widest aperture and does not really improve much stopping down.

The Voigtlander is a macro lens - the large focus throw indicates that it is biased towards the near focus even though it remains sharp all the way out to infinity. Because of this large focus throw, it is hard to catch moving things. It is however so much more versatile because of the near focus ability. It renders really beautifully.

Unlike the Zeiss which seems neutral all the way, the Apo Lanthar does impart a rendition. It is not as well corrected as the Zeiss - one can force purple fringing in high contrast scenes which is almost impossible to do with the Zeiss. I think this less neutral rendition gives it better bokeh and a more 'wholesome' image. My Lanthar also renders a bit warmer, has denser macro contrast and a little less micro contrast than the Zeiss. The Zeiss is cooler and also exposes about 1/3rd less stop.

Deciding which is better is like choosing between a Porsche and a Ferrari - both lenses always astound.

(I've included a picture with a 'gotcha' bug shot - partly for Michael but also to show the almost velvety texture of the Magnolia. The Lanthar renders this beautifully which the Zeiss would not be able to do. Also the Zeiss can't get to this level of magnification. The other picture is the Zeiss which shows some of the bokeh, micro contrasts and the Apo correction - the Lanthar would render this scene more 'romantically'). Both on D800E, handheld and no processing.

I agree with JJChang in most everything, but not in the statements above. I have no trouble with the long focus throw catching moving critters, unless you mean humminbirds and flying insects.

And the Zeiss can get plenty close enough, without extension, as can be seen in this photo taken by the Nikon D810 and the Zeiss 135mm APO:

How would you compare the Lanthar 125mm to the Zeiss 135mm f2 APO? In terms of bokeh, color correction, close and far performance and the maximum magnification you can get with decent results (using extension tubes etc.)

In my opinion you can't compare them. What's the idea of comparing a portrait lens with a macro lens? Without extension tubes, the 135/2 APO goes down to 1:4, the 125/2.5 to 1:1. Yes you can even out the magnification factor with extension tubes but for close-up work, the tele 135/2 can never rival useability or IQ if put up against the 125/2.5. If plants, details, flowers, insects etc. are your game then why buy a tele that only gives you 1:4 magnification factor? Beats me.

For portrait work the 135/2 APO has undeniable advantages, and I would love to replace my 135/2D DC AF Nikkor with it, but have not yet done so (mostly because my clients don't want the skin detail it can resolve in close-up portraits).

Post by: Michael Erlewine on February 04, 2016, 22:29:28
I can’t say one can’t compare the CV-125 and the Zeiss APO 135mm, because that was the first thing I did when I bought the Zeiss 135. The Zeiss is sharper and better corrected. I don’t do much macro, but mostly close-up, and for close-up the Zeiss 135 does a great job if you shoot and crop. The CV-125, like the Noct Nikkor and El Nikkor APO 105 are special lenses.

But from the moment I started using the Zeiss 135, my CV-125 went on general hiatus. And when the Zeiss Otus lenses came along, that only made it more rare that I used the CV-125.

A lot can be done with the Zeiss 135, and it may be sharper than the two Otus lenses (Oti?). However, the Zeiss 135mm is not the only lens you would want to have, but in a way a lens for special work. For a general macro lens, the CV-125 IMO is still the lens to have.

Sure, Akira.

It is a female Nursery Web Spider (Pisaurina dubia (http://www.thenaturephotographer.club/image_tree.php?tsn=887218)).

The last spider is a Brown Widow (Latrodectus geometricus (http://www.thenaturephotographer.club/image_tree.php?tsn=859130)).

Thanks, John, for the identification.  The natural design is indeed full of wonder.

Googling "Nursery Web Spider" gave some info in Japanese, but "Pisaurina dubia" didn't.  Apparently this particular one is not to be seen in Japan.  The rectangular outline in her pose depicted splendidly by you looks very attractive and rare to me.

Thanks for sharing!

They are a fascinating genus.

Here is another species I captured in Florida, Pisaurina undulata (http://www.thenaturephotographer.club/JohnKoerner/191/495/medium).

And still another, Pisaurina mira (http://www.thenaturephotographer.club/JohnKoerner/190/231/medium).

I won't post their photos on this thread, as they were taken with a Canon 7D and a different lens (the 180mm f/3.5L), to it is off-topic.

Haven't been using the Voigtlander 125mm much of late, but took it out on a cool day-off hiking San Dimas Canyon.

The Lupines were beautiful, but everything seemed to be hiding ... however I did find a couple of Honey Bees (Apis mellifera) and a couple of Acmon Blues (Plebejus acmon).

The Voigtländer 125 mm f/2.5 APO-Lanthar is an all-round lens with distinction. Not perfect, as it although engraved 'Macro' by the makers, it is in fact better performing at more distance. Thus I use this lens equally well for landscapes as for details. However, this is not a first-choice lens for portraits of female subjects.

These flower portraits are all very nice, probably taken a bit before 1:2?. The onset of blue fringing in close-ups starts to appear around 1:2 and gets worse at 1:1. That is why I think the APO 125 is less optimised for 'macro' than its designation might indicate. We are talking about a detail in the performance of an otherwise superlative optic, though.

Your opinions are contrary to most.

Most people believe the Voightlander 125mm APO macro has almost no color fringing, including this review (http://thepictorial.com/reviews/clash-of-the-titan-macros/).

Can you show me the color-fringing in this 1:1 image I just shot a couple of days ago?:

(http://www.thenaturephotographer.club/thumbnails/1/1_thumb_0000001449_large.jpg)

My opinion is, if you're getting color-fringing at 1:1, it is only because you're shooting in unsuitable light.

A picture's worth a thousand words: show me your color-fringed 1:1 images, and I will bet in every case the images were in harsh light conditions, not optimal ones.

Isn't that one of the reasons a lens is optimized for a particular task, that it works seamlessly under a variety of different lighting conditions?

Mostly the Voigt 125 APO also does work well in harsher light. After all, we do not always get the choice to shoot in optimal light. The occasional tot of violet fringe in harsh light is dealt with easily enough.

This thread has reminded me to retrieve my 125 APO from its case and get out outdoors with it.  I've neglected it recently. ;D

Added Later:  Here is an MTF test which shows only 1/4 of a pixel of Lateral CA at f/2.5, f/4 and f/5.6.
It's probably hard to get much better than that.  ;D

The image magnification is  not mentioned. The independent observations of slight blue lateral fringing are from near 1:1. Otherwise the APO-Lanthar is as clean as a whistle.

What made me discard a newly acquired AFS 105 mm f/2.8 Micro-Nikkor VR G and let the AO-Lanthar take its position many years ago was the near total lack of longitudinal chromatic aberration ('axial colour') of the Voigtländer. This imparts a special clarity to the images that very few other lenses can match.

I learned of the CV-125 APO-Lanthar from Bjørn Rørslett years ago. And, although I have probably dozens of macro/close-up lenses, the CV-125 is still the best all-around close-up lens in the business. And they seem to be getting less expensive on Ebay than they used to be. I have owned four of these babies, and today have only two, although one is an unused perfect specimen in Nikon F-mount. This is one of those lenses that has its own particular character, one that I like very much.

Post by: John Koerner on June 20, 2016, 06:04:42
I am grateful for both my upgrade to the Nikon D810 as well as learning about the Voigtlander 125 APO.

(http://www.thenaturephotographer.club/thumbnails/1/1_thumb_0000001490_large.jpg)

Here is a real-world example showing the extreme usability of the D810 Base-64 ISO, married with the quality of the Voigtlander 125mm f2.5 APO-Lanthar Macro in salvaging an image ...

(http://www.thenaturephotographer.club/thumbnails/1/1_thumb_0000001473_large.jpg)

The above image is the only capture of this lizard I was able to get before it ran off, while on a hike, which image was severely under-exposed.
(Keep in mind, this image displayed here is only 1200 px-wide, the original image was 7400 px wide.)

With most cameras, that do not have the D810's unique Base-64 ISO, the above capture would have been an essentially unusable image, because all of the detail would have been lost.
However, because the Nikon D810 can still capture incredible detail even in an under-exposed image, I was able to move my slider over to increase the exposure, and crop the image like this:

(http://www.thenaturephotographer.club/thumbnails/1/1_thumb_0000001474_large.jpg)

And from the larger, under-exposed image I was able to develop a full-sized, nicely-detailed image like this:

(http://www.thenaturephotographer.club/thumbnails/1/1_thumb_0000001475_large.jpg)

Even better, because of the extreme quality of the sensor (as well as the Voigtlander 125 f/2.5 APO Macro lens I was using), I was able to crop to an even greater extreme, like this:

(http://www.thenaturephotographer.club/thumbnails/1/1_thumb_0000001476_large.jpg)

The unique characteristic of a Base-64 ISO, plus an exceptional lens, enabled me to come out of this with a very detailed, ultra-close macro-portrait of the animal, like this:

(http://www.thenaturephotographer.club/thumbnails/1/1_thumb_0000001477_large.jpg)

While not absolutely perfect, the above image certainly is usable (and better than many entry-level camera/lens combos can achieve at true 1:1).

Here is a nearly-noiseless, 90% crystal-clear, full profile of this Great Basin Fence Lizard that was able to be developed and salvaged from a rather dark, far-away shot that wouldn't be usable if taken by most systems.

Therefore, while sometimes there are AF needs that this manual lens cannot address (which is where my 300mm VR II comes in), when it comes to quality images, the Voigtlander APO-Lanthar + D810 is a great combination for the nature photographer, allowing him/her to salvage fleeting opportunities that might have otherwise been lost.

A nice demonstration of the capability of the APO-Lanthar 125 (and the resolution power of a 36 MPix sensor). It really is an excellent lens, nobody question that.

However, I sometimes wish its internal construction was as robust as its optical prowess. This is a lens I always have two of with one serving as backup in case of technical issues. Erik (aka 'Dr. Lens') is not always available as a first-aid tech ... My first sample of the 125 APO must have been serviced at least 10 times over the years either by me or Erik. My current work lens holds up well so far, but it's early days yet.
Title: Re: Voigtlander 125mm f/2.5 APO Lanthar
Post by: Erik Lund on June 21, 2016, 10:41:35
Yes a fine post processing sample, I have also great success with the D810 files in low light.

The 125mm APO Lanthar has almost zero CA.

I have never seen purple fringing with the lens, maybe since I shoot with controlled studio flash most the time.

Sometimes I have seen various traces of CA in close up shots from this lens when shooting metal/steel on a black back ground.

The lens internal chassis is not designed mechanically for heavy field use, the internal design with the 'universal' mount is not solid, it's a rather flimsy set of three screws supposed to keep the lens in one piece,

I have repaired several lenses from around the world with issues around that mount area, screws either work loose or the are pulled through the too thinly cast metal.

Over all Voigtlander choose screws a bit smaller/thinner than the ordinary sizes we are used to in Nikkor lenses, I have upgraded several lenses to larger size threads and introduced washers under the heads in high load places, where the metal casting is too thin those has needed any service since...

The focusing threads and guides for the floating elements seems to hold up quite well though so completely satisfactory overall performance for normal use can be expected! ;)

Post by: John Koerner on June 21, 2016, 15:57:42
Yeah, I try to be careful with the lens, as it does seem fragile.

So, basically, if I keep using this lens, it will come apart due to fragile screws? :o

Well, I guess the good news is it can be repaired, and upgraded ... or should this kind of work be done in advance, preemptively?

Post by: Bjørn Rørslett on June 21, 2016, 17:05:04
Opening the lens and replacing the parts that are bound to fail over time is a wise decision in the longer run. The external appearance of this lens matches the excellent optics, but not the build quality.

When my APO-Lanthar failed the first time, in South Africa in 2009, I had only used the lens for less than 2 years. Its focusing collar suddenly jammed. Fortunately, my new-found friend Erik Lund travelled with me and he quickly revitalised the APO-Lanthar by a makeshift repair.

I regard the APO-Lanthar as one of the 'must have' lenses in my various lens kits so never travel without it. To distribute the wear (wear levelling), I have several of them. At present "only" 2, though.

Remove the lens from the camera during transport in a bag in a jeep or an airplane or similar and as always; Don't drop it and you will be fine! ;)

Basically the lens has a 'breakaway' point similar to a Nikkor 24-70mm AFS there are just no spares to repair it with in that point in the lens chassis,,,

Just use it - It's an amazing tool!

Hi folks!  First post here.

How important would you say it is to add a cpu to the APO-Lanthar?  Do most of the users of this lens choose to do that?
Title: Re: Voigtlander 125mm f/2.5 APO Lanthar
Post by: Bjørn Rørslett on June 22, 2016, 08:57:01
Adding a CPU to it helps on several levels regarding exposure consistence and accuracy. Plus of course one cannot forget setting the correct EXIF information ...

Due to the way this lens is built (it has an interchangeable mount), adding a CPU is much more difficult than usual and is best left to the specialists. Putting a Dandelion CPU on it might be a little easier (?), but the documented fragility of the Dandelion is a concern.

Not many APO-Lanthar 125 lenses have been CPU-modified over the years that I know of.  With my CPUs probably max. 10.

Post by: Bjørn Rørslett on June 22, 2016, 09:31:31
At least you can set max.aperture to f/2.5 with the 135 mm setting to identify your APO-Lanthar.

Having a CPU in the manual lenses makes them compatible across the entire range of Nikons, plus the Fujifilm Finepix Sx(x=1-5) line. I use S3Pro UVIR and S5Pro at the moment. Not every one of these cameras allows a non-CPU lens to be programmed.

Yeah, I've never modified a lens, so I'd be way to skittish to try to modify this one.  I've been using extension tubes for close up since my D2H, and just upgraded a D2X to a D500 and decided to buy a real macro lens.  I also ventured into manual focus non Nikon lenses last year with a Voigtlanger 58mm Noct and I really like it, so between that and the great reviews and discussions around it, I decided to get the 125mm.

However, I sometimes wish its internal construction was as robust as its optical prowess.

I have the same feeling too.

This is why I try to be very careful mostly when I focus on a close subject : I turn the focusing ring slowly without force it and thus avoid any damage of  inside helicoid guides, and prevent any play.

I am also very careful when the lens is fully deployed and thus vulnerable.

So, if you are mostly landscape (and even portrait) photographer, the risk is minimized as you work at infinity.

Nobody has any interest in deliberately destroying their lenses? However careful as one might be, accidents can happen and that is where the internal build of a lens shows a difference.

Getting the three retaining screws for the focusing guides replaced by something more beefy or at least put a washer under the existing ones will probably help towards an improved longevity for the 125/2.5. Those screws are really the Achilles heel of the construction.

Of course not.

But such issues could occur by ignorance (for instance if anybody ignores how a lens is made inside) or trying to focus a stiff lens by lack of maintenance (sticky old grease).

This is how we can get great bargain on ebay : many lenses are sold as ''defect'' or ''for parts'' at ridiculously low prices. They mostly need to be re lubricated.

That said, I have never saw a CV apo lanthar sold as ''defect'' (cause stiff focus) so far... ;D

Thanks for the tip about the guides, but not sure I would try to dismantle my CV 125mm. I will leave this delicate task to a specialist !

This is a lens that's been on my list for quite a while as I have the excellent 90/3.5 and sometimes temperamental 180/4.
I have the Zeiss 135/2 which is excellent, but it's big and heavy sometimes and doesn't like being pointed into the sun all that much for sunrise/set landscapes.  I have the 135/3.4 APO Telyt that's also great, but sometimes it's too slow.

How does the 125/2.5 stack up against these lenses at MFD for portraits and at infinity focus for landscapes (wide open and at f/4)?
For portraits I don't need across the frame sharpness like I want for landscapes where excellent sharpness off into the corners is sometimes important.  Immunity to flare/ghosting with the sun in the frame is highly prized as well.

I have an opportunity to by an F-mount version that appears to be in excellent shape.

So the owner has sent me sample jpg images taken with the lens using an EOS 6D (20MP), though there is no aperture information.
The images are hard to tell if the lens is sharp at infinity - so I've asked for the RAW files as well as the aperture the images were taken at.

Has anyone run across a sub-par (for sharpness) copy of this lens?  If so can the optics be adjusted to bring it back into sharpness (and where would this be done)?

It looks pretty good, but I'd hate to have to send an expensive lens off to a repair shop (where?) for an expensive adjustment right away.

It looks like the 20MP sensor has a heavy AA filter - much like my D700 did, which really doesn't let sharp lenses shine - hopefully that's the case.
Hopefully the RAW files will allow me to see what the lens can do if I can get the owner to give me the RAW files.

Leica and Zeiss appear to beat the Voigtlander in this review (http://slrlensreview.com/web/entry/100mm-macro-comparison-part1). (Although it appears the writer never finished the sequence.)

Although many laud the Voigtlander for its bokeh at fast apertures, I also value the lens for its "3D effect" when stopped down (in this case, f/11).

Leica and Zeiss appear to beat the Voigtlander in this review (http://slrlensreview.com/web/entry/100mm-macro-comparison-part1).


This kind of review can be so misleading. The author fails to point out that the Chromatic Aberration on the Zeiss Makro-Planar 100mm makes it  (IMO) unusable for my work. So it is out of the running at the get-go. I sold mine, and it was also too "contrasty" for subtle work, again: IMO.

The Leica is another story. This is, indeed, a superior lens, with an enormous focus throw (something like 720 degrees). Mounting it on F-Mount means for me, having to mannualy open and close the aperture, which is a pain. But, no doubt, a great lens. I am talking about the Leica 100mm APO Elmarit-R lens.

I don't have the Canon, and I have written much about the CV-125, which may not be superior in some ways to the Leica, but as a walk-around, all-around, macro/close-up lens... one with a special draw... I feel it can't be beat. No, I don't use it a lot these days, but when I do I see all over again why it is (all things considered) a wonderful lens.
Title: Re: Voigtlander 125mm f/2.5 APO Lanthar
Post by: Bjørn Rørslett on August 24, 2016, 09:00:21
Chromatic aberrations can indeed be troublesome and the axial colour ('longitudinal' CA) is in particular a headache as it is less efficiently dealt with RAW conversion software. I abandoned the (then new) AFS 105 mm f/2.8 Micro-Nikkor and switched to the 125 mm f/2.5 APO-Lanthar just for this reason as I found the Nikkor's axial colour issue appalling.

A review ignoring such CA behaviour is not providing very reliable information to assess lens performance, whether or not it is presented with lots of graphs and figures.

For the lateral kind of CA, removal by software can be rapid and efficient, thus this issue is not the deal-breaker it once was in the days of film. For some old lenses, in particular wide angles from the film era, lateral CA is nearly always present when the lens is used on a digital camera and software removal has to be considered a normal step in the processing work flow. The 24 and 15 mm Nikkors represent this behaviour and their performance should be assessed after properly dealing with the  lateral CA. Again, these points should be addressed by the reviewer.

Is it a Canon or Nikon mount lens? Is he using an adapter? Is he using live view and zoomed in to do a infinity test?


What I said about adjusting is the infinity setting, it is done on the front group with the lens assembled. I set it to slightly beyond infinity, to avoid problems with the ED elements and the floating elements.

I don't have much knowledge about Canon except some of them have, besides a strong AA filter, also a rather thick cover glass that can create havoc for some lenses...

I think the Voigtländler cumulates several assets :

# apochromatic optics;

# colour rendition;

# beautiful bokeh;

# sharpness (even if it's not the sharpest);

# long throw, which ensures perfect focus;

# and 1/1 reproduction ratio.

In addition of that, few ''subjective'' considerations like 3D effect, rarity, beautifully crafted, good looking.

I am not sure any other macro lens offers all these advantages in one single lens...No wonder it is so popular. :)

The owner sent me Canon RAW files that I was able to decode and the lens is much sharper with my standard post-capture settings than his apparently default-setting .jpg images that he sent.  Still I have no idea what aperture was used and will inquire again with him.  He appears to be a novice as he purchased the lens in Japan at one of the numerous shops and had not used it much.

I'm interested in landscape-type distances and only one of his images was close to being as such + somewhat critically focused, so it's hard to tell how even the corners are (to evaluate for decentering), etc.

The lens looks to be in pretty good shape and comes with hood and original box, etc.

The lens looks near pristine. Get it before the guy changes his mind :D

He said all the test shots were at f/6.3 . . . .????

Clearly a novice at such things, but I've had mixed success buying from such folks as sometimes they don't know what they have and sometimes they are hiding things about the history of the lens.  $1750 he wants - it's been for sale for a couple of weeks now at that price.  What's the going price these days for a near pristine copy with/hood+ box?

Higher than so.

f/6.3, really. That is 1/3 off f/5.6 and with no electronic communication lens-camera, value must be eye-balled ...

The lens looks pristine and well kept. It is not made any more and the combination of its qualities is not easy to find in any modern lens today. You will kick yourself if you let this one go and I doubt you will find another in such good condition. The owner doesn't use it properly - certainly not the way you would! Rescue it!

I will offer something less than $1750 for it and see what he says.  I may have to sell my 135/2 APO Zeiss which I don't use all that much due to size & weight in the bag.

Thanks -

I missed out on the lens with Nikon mount. Does anyone know how easy it is to (let someone) replace the mount by a Nikon mount? I know, clearly a novice question... But I'd appreciate any guidance.

The 125mm APO Lanthar is build with a rear module that is interchangeable with similar rear modules - So Nikon F-Mount from a 40mm f/2 the old version can be used as a donor for a Canon FD, Olympus and the Pentax as far as I recall,,, You can check by looking at the 'look' of the aperture rings.

I have done so a couple of times.

I have also build a home made adapter module from an old F-Mount pre-Ai, one without screw-holes since they are located very differently to a Nikon Ai or Ais mounts.

Very tricky to make the aperture stop down leaver reversing link and to get it geared correctly,,,

But with one of Bjørns G-Type CPUs it works perfectly! :)

I have joined the Voigtlander 125mm club.  I just purchased one from Map Camera in Japan.  I'm happy with the lens, although I haven't used it too much, as yet.  The first photos look very good.  I have noticed a bit of play in the outer housings of the lens, out by the ends of the housing.  By comparison, my Zeiss 100mm Makro has no play, but the Zeiss 135mm Apo has almost as much play.  Hard to quantify.  Is this an issue?  If I mildly  shake the lens, it rattles a bit.  I'm inclined, once I get my grubby mitts on a lens I like, to keep it.  Is CameraQuest the preferred place for repairs in the U.S.?  I don't mind spending a bit extra to get it tightened up.

There should be the very little, if any, play in the focusing ring.

The lens is excessively prone to getting play after impacts to its front. Do get the three holding screws for the internal guide rails replaced. They are the really weak part of the construction. Unlike popular myth and the first impression of holding the lens in your hands, the 125 CV is NOT built like a tank. It needs careful handling.

Thank you.

Thank you for the link as well.  I'm assuming Camera Quest would be able to replace those screws.  I'm not sure I'd like to tackle it.  I've never taken a lens apart and I don't think I'd like to learn how with this lens.  Is the issue that the screws aren't long enough or aren't thick enough?

Reading Michael's review a few years ago, I picked one up. Unfortunately for field use, it came in absolutely mint condition, looking new in the box, including all the original paperwork. I am terrified to carry it around. For me with my propensity for weird bokeh, it has a very bland OOF character, but one I am beginning to like.

When converting raw file from these very sharp lenses,,, the bokeh is very easily made harsh if you are not careful in pp with adding corrections like; clarity, contrast and or sharpening,,,


The sharp portions of the image like it so to say but bokeh can suffer,,,
