    Which lens has the 1-inch focal length? And is that the focal length or the back-focus?

    # 6 of 6 Last one for a while

    This one is simple, it has no markings that I can find with a light and a magnifier. Zilch

    It is 6" tall, Hood OD 3.5" 2 elements, cleaned up nicely, no flange

    If the Beck has a 1-inch back focus, there's something wrong with it, probably the wrong elements. It won't cover whole plate or even 4x5 like that.

    But you have some real gems with the other lenses!

    Flange back focus distance


    The 1st lens I described in this thread, PORTRAIT LENS SERIES C. 8 x 10 Fowler & Slater Cleveland, aka https://amedeusphoto.zenfolio.com/bl...ortrait-4-lens

    Need an idea of rear flange to GG distance necessary at infinity, just to make sure I can get my standards close enough

    I need to modify a camera to fit this monster, it is long and heavy needing a very sturdy front standard

    My SC 11X14 Deardorff has limits, maybe my Levy copy camera is better suited
