An excellent observation: I'd dearly love to retire my 24/2.8 AI Nikkor.

You'll be glad you did :)


The 330 degree focus throw is a two edged sword: This would be a difficult lens to use with a moving subject but superb for working from a tripod at close range.

I don't think 25mms are ever really used for 'moving subjects' ... maybe if reportage ... but it's still not too bad (if you're in the general range anyway).

Maybe if you jump from trying to photograph a bee on a flower ... to bigfoot in the distance ... you might be delayed (but even there, not so much :) ).

IMO, 330° of focus throw is a real benefit in 95% of any instance where you'd want to use a 25mm lens ... either for close-up (flowers) or really trying to nail the general area you want in-focus on a landscape (I often focus on the middle-ground, rather than infinity).

It certainly is a more pleasurable exercise (for me, anyway), compared to a typical landscape lens, with a paltry 90° to 130° of focus throw :-\


Now I'll peek at the price of the f/2.8 and have a little cry.

They're really not that expensive, David.

Brand-new = $1,100.

I got mine, in mint condition, box + everything else, for $624.95 (free shipping from Japan).
In questioning the seller, I discovered mine was "a storefront example," used for showing to customers, without ever actually being sold or used outdoors.
It still had the unclaimed/unregistered warranty card, which Zeiss just honored by confirmation email this morning, as a matter of fact.

Literally, I got this "as good as new" ... with the full warranty "as if" new ... for about $500 off the new sticker price.

Hell of a deal, if you ask me 8)

Great shots, but not for me, way too short working distance...

Thanks.

It is not my usual preferred working distance either (properly-oriented).

However, I can see it being useful for certain applications, giving perspective (subject + environment) that standard macro lenses cannot.

I am thinking of, say, photographing a mushroom at ground-level ... and yet capturing the forest in the background, things like that.

A standard macro would just isolate the mushroom, while this might give a more interesting (or even companion) perspective of the effort.

Bjorn has talked about using the the good 'ol 20mm f/3.5mm with a K-1 ring for similar application (I think).  Of course, the vintage Nikkor is not a modern Zeiss, but the application you described sounds similar.  An inanimate subject would work, you gotta be super close to the subject with the 20mm and K-1.

The Zeiss 25 mm f/2.8 isn't exactly a new construction, either.
It predates the Zeiss 25 mm f/2.0 and the newest Zeiss Milvus 25 mm f/1.4.

Presuming a 3 to 5 year design period before production and first sale, the Nikkor 20/3.5 AiS is roughly a 30-year older design than the current ZF 25/2.8.

To be honest, the detail of this lens, reversed, I don't think is as sharp as my Nikkor lenses reversed. Here is a different crab spider, taken with the Nikkor 20mm AI-S, reversed:


Mecaphesa sp. by John A. Koerner II, on Flickr

The above image was also taken on a bellows, and is about 4:1 (not 2.7), but the Zeiss (while seemingly less-sharp) does seem to have a creamier, less-harsh bokeh, with more pleasing transitions.

As I continue to play with this delightful lens, I am thinking its best function as a nature lens is Plant Identification (near and far) ...

Thanks here are a few that push the color limits (make you want to hide your eyes :) )

One of an Ice Plant (wide), the other at the lens' MFD close to a flower, and the third (reversed) at 2.7x magnification, focus-stacked.

Some more images to show the versatility of the lens:

1. San Dimas Canyon Mountain (Fireman's Trail, foggy morning) @ f/8
2. Western Poison Oak (Toxicodendron diversilobum) @ f/8
3. Western Poison Oak (Close) @ f/8
4. Western Poison Oak (Close II) same as previous, but @f/2.8
5. Flower Crab Spider (Mecaphesa sp.) 15-image stack, reversed, @ f/4

I made a comparison of close-ups, @ f/8 vs. f/2.8, and like the presentation better at f/2.8. (f/8 is clearer ... but f/2.8 draws you in ... kind of a swirly, focused in center-to-less-focused outer, heavy-vignetting effect).

For reverse-image stacks, f/4 is the sweets spot.
