How much sharpness is really achievable?
Since a thread created recently on TP,
(faulty AF, or am I expecting too much?)
I got some emails asking if it is reasonably thinkable to come to a given
degree of sharpness.
Members have read on different occasions that I don't use sharpening
on my pictures but meticulously perform AF-Fine Tune on all of my 16
lenses and 4 bodies — 64 combos in all!
As my work is mainly meant for publishing purpose, sharpness is a very
important prerequisite element. This level of sharpness is my edge over
the tight market competition. Here, like in my hockey coaching, I advo-
cate that winners were willing to do what the losers didn't.
The following example was taken with one of the combos I use for wild-
life: an old pre-VR AF 600 mm ƒ4 (bought here incidentally!) on a D850.
