Re: 24-70/2.8L II field curvature (is this normal?)
Here is an example I just grabbed from a recent set of landscape photographs where I happened to use this lens.
The basics: Canon EOS 5DsR, Canon EF 24-70mm f/2.8L IS at 50mm, ISO 100, 1/80 second, f/11. All images are 100% resolution crops except the first one showing the entire scene.
Manually focused on subject in roughly the center of the frame. F/11 for sufficient DOF, though with a conscious decision to allow the distant mountains to end up slightly soft. (Crops of that portion of the frame not included.)
Full scene:
Center resolution (very slightly left of absolute center):
Lower right corner:
Center left edge — some branches moved, but look to lower right corner for some that didn\'t:
