    Rodenstock APO Enlarging Lenses

    I am wondering if I will see a difference between the Rodenstock Rodagon APO 90mm f4 lens when compared to the Schneider Componon S 80mm f4 lens that I have.

    Prints would be 11x14 to 16x20.

    thanks.

    I don't know about the APO Rodagon but the 90 Schneider HM is spectacular. It covers 6x7.

    this is absolutely my favorite medium format enlarging lens, I think it is an amazing piece of glass.
    It beats the hell out of all my 80mm Apo's.
    the coverage is wonderful.

    Yes you will see a difference. Providing you are comparing the 90mm Apo Rodagon N vs any other 90mm. But if you are comparing the old 90mm Apo Rodagon you probably would not see a difference.

    To see what a lens can do you must be enlarging within the optimization range, use a glass carrier and have a properly aligned enlarger.

    I am not sure how old the APO 90mm is but it has the red ring around it.

    David,

    If it is old it is a 90mm APO.

    If it is not old it is a 90mm Apo Rodagon-N.

    That is the way the lenses are marked on the barrel.

    The N is much less common then the non N version. There were no "in between models" The 90mm N is a totally different lens optically and physically.

    The replacement for the old 90mm Apo non-N is the 80mm Apo Rodagon N. It covers 67 wide open. The old 90mm had to be stopped down to cover a full, large size 67 (there are several different actual 67 sizes that vary depending on the camera or back you use). Additionally all Apo N lenses are multicoated,
