I could use some help from the resident gurus. I am trying to calculate how much shift I can use for my lenses. Here is what I know:
Lenses:
80mm APO Digitar with image circle of 80mm @ f11
35mm XL with image circle of 90mm
Sensor Dimension:
P45+ back with portrait sensor dimensions of 49.1mmHx36.8mmW
Maximum shift available:
18mm Left/Right
So my question is what is the furthest left or right shift I can use without any part of the sensor, in portrait mode, extending beyond the image circle? I have the same question for each lens with the sensor in landscape mode.
Is there a formula I can use (that hopefully doesn't involve pi)?
Thanks to any and all who can help,
Bob
