Re: 24-70/2.8L II field curvature (is this normal?)


OK, with 24-70mm @24mm. 5DsR. ISO 100. 1/60 second. f/16 (unfortunately increases diffraction blur, but chosen here for DOF). Focus is slightly beyond the center trees in the middle distance.

Full scene:






Near center of frame:






Lower left corner — apologies for low detail area:






Center left edge:






At the extreme wide end of this lens\'s range, it will not equal the 16-35mm f/4L IS at 24mm, but it is fine. (By the way, I have no illusions that this is a great photograph, and it has some technical issues. It is a reject that was handy in my raw file catalog.)
