    I get fuzzy corners with my 45mm Schneider APO with any condenser enlarger. Glass carriers and well aligned, but all four corner are fuzz. Put the lens on a diffusion machine and it works like a champ. I have tried it on 4 condenser machines and three diffusions all set in my darkroom.

    The lens was ready to go in the bin at one point.

    I experience light fall off in the corners when using the 40mm on my 67SC condenser enlarger, but I didn't actually print any pictures using the entire frame, so I don't know if there is a sharpness issue. I suspect I will see the same thing you do if I were to do that, though.

    Since I got the lens specifically to crop down bigger enlargements, I doubt that I will be using the corners of the projected image much. If I need to crop down to the corner of the negative, I will probably just move the negative over so the section I'm printing is more centered in the carrier.

    I kinda wouldn't mind having a diffusion head for that 67SC enlarger, but I do have a diffusion 4x5 enlarger and have found that the 40mm works just fine without a recessed lens board. That was a pleasant surprise.

    Thanks for the reply.
