Title: 105/2.5 flare and ghost resistance
Post by: Airy on February 12, 2018, 23:53:25
Mauricio Avila asked the question in another thread ; my general response was, in substance, "pretty good, though not at the level of (say) the Zeiss 35/2". The latter is my reference for a well-behaved lens.

Here is some evidence. Lenses are either the AI or the AIS version. All shots were made against strong backlight. The ones on the sea shore had the sun very near the frame.
There is some drop in contrast and some fringing, but all decent.

Great examples, specially the organs  :D

As you can see, there is some visible blue fringing on the window structures.
All shots handheld, by the way (Df magic).

The Church is Maria Rotunda, in Vienna (Austria). The sea shore is opposite the place where I grew up, 1964-1970. Praia do Molhe, Porto, Portugal.

The organ pictures should also go into the organ thread. Excellent !

Airy,

Beautiful images, especially the organs.

Thank you for the evidence about the flare and ghost resistance of the 105mm 1:2.5, I am considering one unit for landscape and cityscape with strong backlit. My reference for a well-behaved lens is the 28mm 1:2 Ai-S.

Saludos,

Mauricio

Beware, if you buy one, you'll find out it is "for everything".
Not really though, since the 105 does not do close-up shots. That's the limit maybe.

Concerning the backlit stuff, please consider that the "Praia do Molhe" shots were minimally processed (no attempt to enhance contrast) ; the organ shots received "my normal" processing using LR (some noise reduction, some re-balancing of highlights and shadows...), excluding extreme measures such as HDR or fringe suppression.

one of Nikon's best lenses...i just hope that they made an AF version of this :o :o :o
will it sell? maybe, as a specialty lens ::)

An optimal choice for another reason : in  absolute terms, the 105/1.8 AIS is at least as good optically (forget about the widest apertures, f/1.8-f/2.0 though), and probably better in terms of handling backlight or point light sources. It is my 1st choice for stage shots. However, bokeh is slightly worse, despite the 9 blades. For your described usage, the smaller, lighter 105/2.5 is the better choice.

Well, the AF version being larger, bigger and surely heavier, I'll keep with the original model... ::)

I have the AF "version" - 105/2.8 VR. It is an entirely different lens. It is a good one, also one of my first acquisitions when I started my Nikon Digital story with the D700, back in 2009. I thought it would become my go-everywhere lens.

However I seldom use it. IQ is not questionable, but bulk and weight kill me. I'd rather take the Zeiss 135/2 for the sake of its f/2 magic (and even better IQ, overall).

The 105/2.5 remains my #2 walkaround lens (some fifties share #1 ranking : Leitz Summicron R 50/2 with Leitax mount, and Zeiss 50/2, mainly)

I love the 105/2.8 AF D Micro.  It's smaller and lighter than the VR and just a bit longer than the 105/1.8.

Airy,

I was thinking to buy a Canon type 250D close up lens for the 50mm and 105mm focal length  8) that expands the limits a little bit.

Contrast in your sea shores images is very good. I find it quite acceptable for my purposes.

Saludos,

Mauricio

Indeed, close-up lenses are wrongfully neglected these days. I have only one such lens, it came with the Voigtländer 40/2. It seems that IQ suffers less than with extra extension.

Yes.  Another very good choice are  the Nikon Close up lenses. They are two-element achromatic lenses that still maintain a high image quality (The 3T,4T, 5T and 6T).  The 4T (max diopter) for 52mm  and 6T for 62mm.  With step up rings up to 72mm is possible. I use them a lot, easy to pack in the camera bag and easy to screw on the lens and use. They just can make the difference, even on a wide lens like a 20mm.

Have never been able to find these i know there are alternatives like Marumi and others.

Fons - the Nikons are actually very good and better than other brands. The Canon ones are not bad.
It has been written that some lenses are REALLY good with them - but the 50-135mm AIS 6T combo is truly exceptional.

I took some time and got the whole set over a few months from ebay. They come up all the time. I think you'd enjoy using them.

John, What sort of container or case do you use to transport your 5T and 6T in the field? 
Title: Re: 105/2.5 flare and ghost resistance
Post by: John Geerts on February 16, 2018, 21:28:51
The 4T is an easy one, the CP-6 is a good case.  For the 6 T  I use a lens.  Most of the time the 20/2.8 AF.  I then have a small combination, a 20mm + the 6T.

Keith, I have a set of these "filter stackers".  They protect the glasses very well:

I have the 4T and the 6T and they have worked well for me.

They do come up on Ebay, but they are not "thick on the ground".

I have heard good things about both the Canon and Marumi offerings, so there are alternatives to those from Nikon, and I understand that the Marumi close up lenses are still being manufactured, so sourcing them should be less problematic than those from Canon or Nikon.

Thanks Akira.  I hadn't thought of 'Stackcaps'.
