Speaking of Dagors, is it normal for them to be a little soft wide open? I have an unnamed goerz lens that I think is a dagor but it is slightly soft wide open. Perhaps it is a trigor instead?
Yes, i have 4 Dagors, all coated and i do find them slightly soft wide open and in addition they have a little glow in the highlights due to less than perfect correction for coma. This is one of the signatures that makes the Dagor so special.
