Long Process Lenses for Landscape? 24" RDA? APO-Nikkor 610/9?

[CreationBear]

A photo for reference, the late, aluminum barrel 24" RDA on top of the Apo NIkkor 610.

Ha, that is a bulky lens, but one thing that led me (halfway) down the path was that the 610/9 still isn't quite as heavy as the Nikon 600mm tele.

Vaughn--your times are interesting: with FP4+ I'm almost always having to deal with reciprocity and exposures between 30 seconds and three minutes. (Your canopy might be high, but I guess mine is thick.)

Otherwise, thanks for all the replies. One more question, what would be the process for fitting an RDA into a Sinar board assuming I don't have an universal iris clamp? I'm thinking SK Grimes might be the place to start, but any tips appreciated.

CB, out of curiosity I did a search for RD Artars' weights, found this: https://www.largeformatphotography.i...p/t-82143.html. It gives a weight of 41 oz for the 24 incher. Could be for a lens in a brass barrel.

My Nikon catalogs say that the 600/9 (tessar type) and 610/9 (dialyte type) Apo-Nkkors weigh, respectively, 775 and 1,450 g. FWIW, my 610/9 A-N is in an aluminum barrel and weighs 1,377 g.

Those times were for out in the sun and trying to use a shutter-less lens.-- in the redwoods it is several minutes plus.

Thanks for the info--I think you're right about yours being a brass construction, though in the cosmic scheme of things folks use those plasmats-as-big-as-your-head in-shutter and seem no worse for wear. Otherwise, that's an interesting data point about the relative sizes of the APO-Nikkors, though I've not seen a 600mm listed.

exposed in a Tachihara 810HD triple extension field view camera fitted with an Apo-Nikkor 610mm f9 lens working at f128.

Why f128? So I could give a 2 second exposure via lens cap. Can't do faster with any accuracy.

Excellent, the Nikkor is certainly handling the busy background at that aperture at least.

I use Nikkor 610 f9 APO aluminum

Very sharp light and useful on 11X14

Oooo. Like It!

This platinum-toned kallitype print was shot with the 610 apo-Nikkor at f/32, 1/8 second. I focused on the eyes/nose.

The APO ronar 600mm f9 and APO Nikkor f9 are HUGE. What gives the APO artar some added appeal, at f11, it is smaller and a bit easier to manage than a f9 lens at this focal length.

There are two versions of the APO artar, the original Goerz versions have a brass barrel (like the one pictured) these tend to be heavy. Later versions were made with an aluminium barrel. These are lower weight with the same optical performance and nice round iris. IMO, if taking a lens like this outdoors, the lighter weight aluminium barrel version would be preferred, but far more difficult to find these days.

Lesser known are Boyer APO-Saphir, Repro Claron (not sure they made a 600mm), APO skopar, APO-Germinar (Zeiss Jena) and .. these should be considered as longer than normal focal length lenses.

Schneider made a 610mm f/9 Repro Claron and it fits directly into a Compound V and Compur FS 5 shutter. I know it because I just offer one of this here.
Whats about the Apo Tessar lenses? I have a 300mm one in use for 4x5" and I´am very pleased with it. Lenses are available with uncoated and coated lenses. The earliest versions are made ~1910 and the latest in the 1960th I think.
