Will Apo NIkkor 360 cover 11x14? Other 14" that wi

[brook]

I know the coverage is big on these, but this big? Any other 14" process lenses that will? I am looking more for practical knowledge than info from charts.

Thanks

The 14" Apo Nikkor, or any other 4 element (dialyte) repro-lens will illuminate the whole plate, but corners will be mush no matter how far you stop down. To cover, you need one of the 6 element process lenses (plasmat), like the Kowa-Graphic, G-Claron, or the much coveted (and currently unaffordable) Computar.

[Steve Hamley]

The 14" Kowa is also a 4/4 dialyte, at least according to the reflections in the one I have, which are identical to an Artar.

Thanks again you guys. If I recall, a 14" commerical ektar would cover wouldnt it? I dont necessarly need a process lens, but would like an affordable 14" with lots of movement, and classics and barrels are just fine.

[Ernest Purdum]

The 14" Coommercial Ektar, according to Kodak, will cover 11 X 14 only when stopped down below f16 and without any allowance for movements. Other Tessar types would probably have similar performance.



The "classics" that would cover 11 X 14 at a focal length of 14" or less are mostly symmetrical types, often convertible, Protar Ser. VII, Dagors, Turner-Reich, etc..

It doesn't take that steep of an angle to cover 1114 at 14". The only lenses that won't do it are the Artar types. Repro Claron's won't, 14" RD Artar won't. 6 element plasmats work best. Schneider G-Claron is king. Most any 14" Tessar type will cover. I've used Kodak Ektar and Japanese Osaka. Both would cover with a little movements. I'm currently using a big Symmar I got on EvilBay for under $300. Massive lens and coverage but impossible to put filters on. G-Claron has a liveable filter size of 77MM. Rodenstock Gerogon would be an inespensive choice but can't be mounted in shutters. Dagor's and Protars that cover 1114 are EXPENSIVE.

Jim,

How much movement do you get with the Symmar on 11x14?

[Jim Galli]

How much movement do you get with the Symmar on 11x14?

A bunch. Never found the edge yet. 3+ inches? It's the 1980's multi-coated model that the lens list says has 500mm circle. That 500mm may even be conservative.

As I've used my G-Claron 355mm with 12x20 I'm sure it would be great for 11x14.

A 360mm F9 WA process Nikkor will cover sharp to the corners. This is not the regular F9 version. This is a more rare lens. Emile/www.deleon-ulf.com

[Dan Fromm]

Emile, were you thinking of the 260/10 Process Nikkor?

Regards,

Dan

Hi Dan,
The 260mm f10 process Nikkor will cover 11x14 too, I plan to have Steve Grimes Co. put one in a shutter for me this year for my 7x17. I cant say enough good things about this lens.The 360mm WA Nikkor f9 is a different and a kick ass lens, ask Dagor 77 about his. I think he got rid of his 355mm G-Claron after he saw the results of the 360mm WA Nikkor. It covers 12x20. I think they are both great lenses but the Nikkor is very hard to find. You can see one on my 7x17 on my site www.deleon-ulf.com. The good part is the shade for the 260mm fits the 360mm too (360mm doesnt come w/shade). But the shade has to be ground out on the sides for use with the 260mm /7x17 or it clips the neg. Also... I will get you that info I promised awhile ago, I havn't forgotten. Emile.

If money is less of an object, then you can do no better than to locate a 14" Goertz Blue-Dot Trigor (like an artar with wider coverage) - from the last batch produced by Kern Optics in Switzerland.

When I built my first 11X14, years ago, I had the same need for a moderate wide-angle optic for this format. First I tried a 14" Schneider/Goertz Dagor (last Gold-Dot version after Schneider bought the name), but found a bit of field curvature with this lens and this format. Then someone suggested the Trigor, and I found one at Lens and Repro, in new condition from the last (Kern) batch, in a Copal shutter, for about twelve hundred bucks.

To test the Trigor, I taped strips of 35mm Agfapan 25 inside an 11X14 holder, at the center and edges, knowing this would be far more brutal than using sheet film for this purpose. The resultant negatives were every bit as good, area by area, as my Leica M-series negatives! Yeah - I know, this is probably overkill! Sadly, I sold this lens a few years ago. While the Trigor is rated as f/11 - it does open to f/8 to make focussing easier, although this aperture isn't marked. And no, I didn't have any problems with focus-shift upon stopping down.

If you're interested in this lens, try calling Lens and Repro. I saw one advertised there a few months ago, and they might at least know who has one if they don't. Be aware that this last Kern Optic run of Trigors was very small (I've heard that as few as fifty of these exist) - although the earlier Goertz models are a bit more common, and usually come mounted in a barrel.

For something a bit easier on the wallet, I've heard great things about the Apo-Kyvytar (from the old Kyvyx corp), - another process lens which you can sometimes find mounted in a shutter.

Excuse me - Goerz - not Goertz! Whew!

[robert_4927]

John, I use a goerz blue dot trigor on my 8x10 and 8x20. Sharp as an artar and covers like a dagor. The only way to get this lense from me is pry it from my cold dead hands. Amazing little 14 inch lense.
