Does this lens support AF?
Could you upload a sample full-size pic illustrating the quality of the lens? A brick wall or smth like that?
Just by way of helping, I have a landscape with a printed res chart at centre shot and at edge, at both f4 (I think) and f11. Thats 4 Phase one P45 shots at about 40mb each. I can put them up for you to download.
If you'd like me to do so, perhaps you could PM me.
