Consensus on 24-70/2.8 II field curvature at infinity focus?

Name one Canon lens prime or zoom that doesn't have some field curvature (at least below 200mm where my experience lies). The very famous Zeiss 21mm has that gullwing pattern but folks manage to use it for landscapes anyway.

You are confusing "(focus) field curvature" with "distortion".

Where or how did you get this idea? Name me one Canon lens that produces an image exactly as you see it.

You mention gullwing pattern DISTORTION but this thread is about focus field curvature.

Distortion is easily corrected, there is no correction for focus field curvature.

'exactly as you see it' makes no sense whatsoever. Distortion is a deviation from a rectilinear projection, not a deviation from the view of a the human eye.

Plenty of Canon lenses have a much flatter focus field than the 24-70mm f/2.8 II, even the cheap 40mm pancake does.

I could mention IQ, flare and any number of other lens aberrations and properties that could ruin the road to image perfection, but dissing the 24-70 II on field curvature is nitpicking.

What makes no sense is that you dare to suggest that the absolutely middling 40mm pancake would make a better lanscape lens than the 24-70 II on the basis of incrementally flatter field curvature.

The field curvature of the 24-70 II will NOT affect this person's landscapes to the degree that he or you are letting on. Period. I'd like to see samples from your own camera and 24-70 II that proves otherwise.
