    Enlarging lens image circle

    Any chance, that anyone knows the image circle of a Schneider-Kreuznach 300mm 5.6 enlarging lens?
    Thanks!

    Which one? Componon, Componon-S, others? Schneiders MTF curves for the 300mm Componon-S are for an image circle of 364.5mm. Of course the usable image circle depends on your print size.

    Depends on distance to paper when in enlarger

    Enlargers vary

    Wall projection with horizontal enlarger can make big prints

    What do you want to know? The size of the negative the lens can be used on or how large you can print with it?

    8x10, as large as you want.

    Sorry, should’ve been more clear.
    I want to use the lens in a 8x10 camera, not in an enlarger.
    It’s a Componon, 300mm, 5.6
