Do any of you have samples of images shot in color with non color corrected lenses? I would especially like to see any figure/portrait examples.
Thank you
George

George,
Non-coated does not necessarily mean not corrected for color. I have an uncoated Gundlach Hyperion portrait lens described in the literature as "fully corrected for color".
I've also shot many uncoated lenses with color film, and the results can be very surprising and pleasing, especially using high contrast color transparency. I have an uncoated 180mm Berlin Dagor I particularly like. Keep the glass of an uncoated lens shaded for more contrast.
You do need to be sure the glass is crystal clean (uncoated lenses are generally 60 years old or older); any haze will give you results not desired by either the manufacturer or you, and this also applies to coated lenses. Finally, any result you see on-screen will likely not convey any truly representative information.
Cheers,
Steve
Not LF, but here's a shot from an uncoated Heliar on a Voigtlander Superb TLR. The film is Fuji RMS.
Not a coated lens, but seems well corrected for color and chromatic aberration. Contrast is a bit lower than a modern lens, as expected.
Here are two.
The "cityscape" is a slight crop from a 4x5" slide shot with a 3 1/4" WA Rectilinear of doubtful origin, the little fount was shot with a 15cm Zeiss Doppel-Amatar.
In both cases the reduced contrast was what made it possible to get the exposures - on Fuji Astia.
i wanted to try my 2x3 format Busch Pressman Model C with some chrome film. I cut it down from 4x5...i specifically wanted to see how color and portraits worked with the uncoated Ektar 101mm lens (sounds like you had the same curiousity). the lab was kind enough to deveop this non-standard sheet size, and it worked. film is either astia or provia (i tested both, can't recall which this particular shot was). you can see some flare on the highlights, and this in the shade. also doesn't help that my four year old can't stand still long enough for me to get a film holder in place, so the focus is a bit off. but gives you an idea at least...
shot at f/4.5 i believe.
Un,George, if you're thinking of lenses that aren't achromatic, the short answer is that they aren't suitable for use with color films. Most, if not all, of the relatively modern anachromats are soft focus lenses, use chromatic aberration to gain softness. With color films this causes, I'm told by a friend who has several Boyer Opales, horrible color fringing.Originally Posted by George Kara
Is that what you were asking about? FYI, virtually all modern (certainly post-1920 or so) lenses are pretty to extremely well corrected for color.
Good point, Dan.
Even the old WA Rectilinear consists of two achromatic doublets!
I haven't tried a Periskop (two uncorrected meniscii) with colour film - yet another point on my "things to do" list? I have a few of those too - a Voigtländer W.Z., and a meniscus "Satzobjektiv".
Rippo, Kodak never produced an uncoated Ektar. Your 101 Ektar is coated, but only on the interior surfaces of the lens. This coating was considered too soft to stand up on the outside surfaces. It was soon replaced with a harder coating on all surfaces.
George, I have used a very high quality cemented achromat telephoto lens with color slide film. It is coated with modern material but still has pretty bad fringing on the red end of the spectrum. Not something you would want to shoot a wedding with. A red fringed moose against a snowy background isn't any fun either. There is a huge difference between uncorrected and uncoated. Most lenses I've used that are newer than the '30s will give pretty fair color. Even simple meniscus lenses.
Glenn: i did some googling on the ektar and saw a few references to it being uncoated. thought i had a winner (or..er..loser?). anyway, disregard my pic then. i'll have to wait until i have my homemade lenses up and running in a week or two.
The Verito produces some quite visible color fringing. I've posted a detail showing this as well as a couple of other color images made with the Verito in this thread on APUG--
