    65mm vs. 75mm Super Angulon for Linhof Technar?

    They are both excellent lenses. Choice is how wide. Noy how good.

    65mm vs. 75mm Super Angulon for Linhof Technar?

    Mark: The 65mm SA is generally considered to cover 5x4 only 'in a pinch'. It's really a 6x9cm format lens, and it won't cover 5x4 properly until it's stopped down to at least f/11. Even then, the illumination fall-off in the corners really needs a centre filter to even it up, losing you about another 2/3rds of a stop of precious light. The 75mm SA would be the safer and more versatile option, IMO.

    65mm vs. 75mm Super Angulon for Linhof Technar?

    The image circle of the 65mm Super Angulon @ f22 (the optimal aperture) by Schneider's literature is 170mm which easily covers 45. At f22 on 45 you would have enough coverage with an adjustable camera, for 12mm of rise and 10mm of shift in horizontal position.

    Unless you are looking at an Apo Grandagon 35mm none of the modern wide angles are designed to be used at f11. They are mostly all designed to be used at f22 ( Apo grandagon 45 and 55mm are f16).

    If you need the coverage of a 65mm the 75mm will not be acceptable. Both lenses are more then adequate of covering the 45 maximum image on a Technar. Both will probably benefit from the center filters.

    BTW the 75mm has a 198mm circle at f22 and has 30 and 26mm of movement.

    Schneider uses 153.7mm as the diagonal of a 45 negative.

    Sorry to drag this back up from the dead - Bob, the 65 performs best (sharpness) at f22?

    The 75 is as good a performer as the 65. There is no "best" between them.

    Mark, I used a 65mm in the Sinar Handy. Yes it had some falloff but not a lot and I liked the look. With the handy on a non-shift lensboard, you were using the center of the lens and falloff was more uniform than you would worry about if you shifted the lens board. I remember the Technar (and still search on the bay every once-in-a-while) I don't think they had shifting boards...I now use the lens on a standard linhof board on my 5x7 Technika V. I haven't done a critical test but use it along with a 72mm XL. It looks good. I should mention I use it on 6x17 roll film with a center filter now. When I had the Handy, I didn't use the center filter.

    Which flange focal distance could the Technar accommodate?

    Both lenses (65mm and 75mm) have different flange focal distances:
