I recently acquired a 1Ds MKIII and paired it with the 16-35 2.8L II. Given that I've heard about vignetting and light fall off in the corners with this lens on a FF body, I thought I'd "max out" the settings to see for myself.
These test shots were taken at 16mm @ f2.8. This of course would be rather extreme, but is this to be expected to the extent as shown in the photos? Granted I will mostly be using this lens for landscape and outdoor shots at f8 - f22, so this would essentially be a non-issue... and when this would occur, I would edit in PP.
Just curious about your thoughts about this lens/body combo when pushed wide open.
Thanks in advance.
