    My 210mm Graphic-Kowa covers (or at least illuminates) 11x14, but without movements. It's extremely sharp on 8x10.

    The one in shutter almost covers 11x14 but clips at the edges even at f/22 or f/32 so contact prints become a problem without cropping.

    I haven't tested the new one yet that's a barrel, I will once it's back from SK Grimes which will be in 6 months because first I need to find a shutter.

    Unfortunately I don't have a way to measure it with high accuracy just now, but FWIW, fiddling with a couple of rulers, my 150 Computar in Copal 1 appears to be a hair longer than 38mm in length. Stopped way down - I use it most commonly at f/45 - it covers 6 1/2 x 8 1/2 crisply with room for movement. I don't recall ever exposing a sheet of 8x10 with it, though.

    I had a GK210 loaned to me for a week, and found that on 8x10 I had a usable IC of about 380mm.
