| p.1 #5 · The world's sharpest lenses |
I don't want to buy into the exact choices, but will note that of the 10:
one is f2,
five are f2.8,
two are f3.5, and
two more at f4.
Slow lenses are the sharpest lenses, this group average f3.1.
So assuming their methodology was not entirely unsound - and I agree with MJ re the lack of 50mm lenses which regularly top photodo summary numbers - aberration correction of fast lenses carries a heavy penalty even at sharpest apertures. That is my experience also.
OK, I will say more - the 3.5/18mm ZF is not within a bull's roar of the CY 2.8/21mm, not even close. Of course I use ZEISS data, I think maybe they have a better handle on such matters than this fanciful rag.
