    I used to have one of these, and my example just barely covered 8x10 with any degree of sharpness. The circle of illumination was fairly wide and lit up an image closer to 10x12, but the corners were quite mushy beyond 8x10.

    I'd wager that's the f/4.8 Acuton, a Plasmat design. The 12-inch f/4.5 is a Tessar, a completely different beast.

    I know! I was looking for (and appreciate) the answer. I found it strange that the seller of the banquet camera was convinced that this lens was normally used on a 7x17.

    Thanks for the confirmation of its unsuitability!
