Those images don't look as good as I was expecting after reading http://www.lensrentals.com/blog/2015/02/canon-11-24-f4-l-mtf-tests
Pretty interesting test results, really, from LensRentals.com whose reviews I tend to like over most others. Of particular interest to me were these:
"No, the new Canon 11-24 f/4 L lens doesn't resolve as well as the Canon 24-70 f/2.8 II at f/4 at 24mm. Nothing does, really. But it's decently close to it, and this is actually a good performance."He basically says no other zoom lens on the market can touch the 24-70 f/2.8 II ... but this 11-24 comes close ... which is remarkable, considering it spans a more challenging range to try to excel at. It trumps the highly-regarded 16-35 II on all levels.
Even more interesting, where other super-wides are usually sucky at the very super-wide setting you're paying for, only taming down to acceptable as one zooms-in closer, he says the opposite is true with the new Canon lens:
"If you're like me, you had to look twice to see that there are some definite differences. The lens is actually a tiny bit sharper in the center at 11mm. The outer 1/3 of the image has a tiny bit lower resolution at 11mm compared to 24mm. But the differences are pretty minor and I doubt any amount of pixel peeping could show them to you.
"The truth is the two (extreme) ends are so similar that I redid testing just to make absolutely certain we hadn't messed up. You rarely see a wide zoom where both ends have such similar image quality. I was totally shocked that the lens would have this kind of performance at 11mm.
...
"Canon made the widest full-frame rectilinear lens available, and made it with superb image quality throughout the zoom range."I might add it seems to have miniscule distortion at the ultra-wide end too, compared to other ultra-wides, which is also remarkable. I honestly can't wait for this lens to come out ... this is definitely something worthy of investing in. The truth is, the quality/lifespan of the best lenses FAR outlasts/outweights worrying about camera bodies, which become old news by the time you break them in. It will be a long time before an ultra-wide will touch this lens IMO.
