By reputation, the very best 35 mm. lenses are said to be sharper
than corresponding medium format lenses because they have to be
(i.e., to get good image quality in the smaller negative). For the
reason given in the first paragraph, I don't know this personally.
It is just something I have read.
But if MF lenses are less sharp than 35 mm. lenses, I wonder if
existing MF lenses will be good enough for a digital sensor? As we
know, some lenses that do well (or okay) in 35 mm. do not perform
so well on APS-C. Will 645D buyers need new lenses?
Jostein made some tests. FA645 35/3.5 is about as sharp as 31/1.8
Ltd. Most of lenses for 645 is of very high optical quality, just a
few are weak - for instance FA 45/2.8, which is actually worse than
FA 45-85/4.5 zoom... So I think majority of P645 lenses will work
very good on big sensor.
