Have you had a chance to do much side by side testing yet? I've been surprised that the 5N shows better corners even with longer RF lenses, from what I've seen so far, although the difference isn't nearly as drastic as with the really wide lenses.
Hi Douglas--forgot to answer you, sry
I just went and looked over my shots with the nikon 28/2 and the canon 24/2, both SLR.
The shots are into the mountains from 1 to 15 miles. This, as you know, is pretty demanding.
If anything the n5 appears to be slightly better in the corners. I have not tested with RFs directly, but maybe I should.
These are shots around f/4 so that also may be an issue.
If anything the RF wides seem superior to the SLR wides on the n5n. These little skopars are really incredible in the center frame. My 21 blows me away in some of these shots---but not on the edges--however again I am up around f/5.6.
Here is the 35 skopar on the 5n
check out the
upper left corner on the full size.
I'm seeing this on nearly all my wides--but not on the 135, for example.
thats the canon LTM 135/3.5 (
full)
I suspect the borderline of infintiy edge performance is around 40mm---but you may be able to demonstrate differently.
Maybe when you get a chance shoot some of your 28ish glass at 1 mile + and take a look.
