In the center I don't see anything
to sweat about.
While the Sony Zeiss 24-70mm FE has a poor reputation for corner
performance, it's smoking the Nikon prime here.
At f/5.6 the vignetting is present but less pronounced on the Sony
Centers at 5.6
Corners at 5.6
Center crops at f/8

Corners at f/11
The Sony Zeiss 24-70mm f4
FE has similar
performance at 28mm
: Sharp in
the center and
good in the corners at f/4. Then it just doesn't improve while stopping
down. The Nikon 24mm f/2.8 AI certainly shows it's age wide open, yet
is clearly better in the corners, but sightly worse in the center at
f/11. What it loses in the center is a little contrast, easy enough to
fix in post processing. This just goes to confirm what is
much common knowledge, the Sony Zeiss 24-70mm f4 FE was not built for
landscape shooting. Having shot three weddings with it, I can attest to
its prowess for event work.
