I'm looking for an inexpensive 90mm lens to shoot on 8x10.
What I'm most interested in is how a lens falls off at the corners, i.e., is the transition to dark corners smooth and gradual or is it a well-defined circle?
I would like to find a lens with a soft, gradual falloff, not one that produces a circular image on 8x10.
With that in mind, I've compiled a shortlist of possible candidates:
Schneider Angulon f6.8
Topcor f5.6
Graflex Optar f6.8 (Wollensak)
Does anyone know the falloff characteristics of any of these lenses?
It would really help me nail down a suitable candidate.
Thanks in advance.
