There seem to be a variety of opinions of this lens. Now that Schneider has ramp ed up production, and prices have fallen, I was interested in comments from thos e using the lens.

I will use it exclusively for 4x5. Is it as sharp as claimed? What about light f alloff on 4x5. Several posters have questioned whether it is worse in this aspec t than say a 90mm f4.5.

I have looked at the graphs on Schneider's web site, and they seem to indicate t hat it has the same falloff with angle as about all of the other lenses, I presu me close to cos^4.

Thanks for sharing your experience since this will be my most used lens.
