I happen to have a near mint Symmar 5.6/150, and I've been unable to find any specific info aboutwhether it covers 5x7 or not. Schneider mysteriously says the 135mm Symmar is for 4x5 and the 180mm Symmar is for 5x7, so the 150 seems to fall somewhere in between.

I've found comments by users that their APO-Symmar 150 just and so covers 5x7 with no movements, but no comments from users of the old Symmar like I have on 5x7.

Has anybody used an old Symmar 150 on 5x7?
