Here we compare the 24-70mm f/2.8L II to the three Canon 50mm lenses: the 50/1.2L, 50/1.4, 50/1.8 II.
All three primes (like virtually every 50mm lens out there) have field curvature— and I have tested over a dozen designs; none are free of it. As a result, comparisons are going to reveal more here about how the target was “sliced” by the zone of sharpness of each lens.
For this comparison, I increased my normal sharpening amount to Amount=80 to really bring out the fine details possible. This aggressive level of sharpening is just fine so long as the exposure is full ETTR, as it is here.
