121mm Super Angulon

[Dan Kowalsky]

Hello every one, I have a question about the 121mm Super Angulon lens I purchased and has not yet arrived. This lens has an image circle of 290mm @ f22. That is about an 11.6 in ch circle. When I measure diagonally across the 8x10 negative it measures just u nder 12.5 inches. That would leave about 3/4 inch in the corners that will be vi gnetted. If I stop down to f32,f45,or f64 would I be able to cover this entire 8 x10 negative with no movements? This lens would be used as an ultra wide for my Master view 8x10 and as a full coverage for my home made Hobo, also 8x10. Thanks in advance for any comments.

Dan,

I believe the IC is 290 mm@f16 with 100 degree angle of view (black version). You can step down to f32 to cover 8x10 with just a bit movement. Light fall off at the corners, but it should not be a problem for B&W. My concern is that the angle of view is too wide and it covers too much, my points of interest get lost in the whole pic. It's good for grand landscape. I suggest you email Roger Hicks, it's his favorite lens!

I know nothing about the image circle of the lens, but in proctical terms I have done a lot of interior shooting with my 121mm when not much else will do, and I even get a bit of movement, and certainly full coverage without a whole lot of drop off in the corners (b&w only so far)at f/22 and f/32. Stopped down more I even get rise in the occasional vertical tight exterior shot.

Thanks for the spec's Geoffrey. The Gran landscape is one of the reasons for the wide coverage of this lens on the 8x10 format. I also think this would be a great street shooting lens on my Home made HOBO. I assume focus is from 4 feet to infinity at f22 or smaller. Check it out.(www.dankowalsky.com/Equipment.htm)

...Forgot to mention. The lens in the H/M HOBO for now is a Kodak 127 ektar

You got a very cool LFPS! You should get a Linhof wide angle lens focusing track to adding more focusing flexibility to your HoBo.

I did not use it on 8x10 but a friend who just bought the lens from me has made a 8x10 chrome and is happy with the coverage (maybe he will relate his findings?). He even used a little bi t of rise. As often said, Schneider have very high requirements when they put forward the specs for their lenses. Cl osing down to f22-32 should be enough. Beyond, the diffraction will affect the sharpness of your neg and is not recommended. A 121 mm lens on 8x10 is equivalent to a 18 mm for SF!

Hi Dan, I use my HOBO with a 121. It's perfectly fine. No coverage problem Difraction doesn't occur and perspectives are beautifull. 18mn doesn't mean anything in large format. Regards.
