I'm surprised the difference isn't as great as I thought.
Based on results below, it looks like the 2 lenses are almost identical in corners, which is amazing that the 24-105L can stand up to a prime in the corner.
In the centre, the 24-105L is a smidge worse, but it is not a day and night difference.
However, what does stand out more is that the 35L has:
- Better Contrast
- More vivid colours
- More "pop"
- Is so sharp at f/4 it causes the sensor to show moire
- Brighter at any given aperture
By extrapolation, 35L > Zeiss 35
DPP raw conversions
All NR etc. disabled
Camera in same position
Manually focused in Live view, and used Contrast Detect AF, then picked sharpest of each set.
if that was on the 5D2 your 24-105 does pretty well in the corners, maybe 35mm makes all the difference though, i only carefully tested edges 24mm and 28mm, the two i tried looked way way worse than that, especially on my real world shots where the edges and corners were really bad (perhaps the FC of the 24-105 fits very poorly to some of the compositions I shoot)
your 35L blows it away in the center though
i supposed some of it can be in the focusing though, i found that you really need best of at least six attempts to fairly compare, although it sounds like you gave it a few tries, not sure how many
and perhaps the extreme colors mask corner CA and blurring?
