First camera was a dig*, second was an F3.

I think I would verify that infinity focus is accurate first. focus at film plane, then check VF. If they DISAGREE, adjust the focusing ring.
FWIW Practical infinity is around a block away, theoretical is 500 or 1000 times the focal length. top of an antenna/water tower, high building etc.
I'm wondering if it's a problem with the error on the electric camera and shimming of some sort. I understand there are a lot of the Voigtlander and FSU lenses that need to be shimmed to focus properly on those things.
