Roger Cicala of Lens Rentals posted MTF charts and other lab analysis data of the Sigma 14-24mm f2.8 Art lens.
In the conclusion he writes:
I said at the beginning that I expected this lens to be at least as good as the Nikon 14-24mm f/2.8 and better than the Tamron 15-30mm f/2.8. I think it’s pretty apparent that while they are all within hair splitting distance of each other at 14mm, the Sigma is the best at 24mm. Optically, this one is worth the money and the best overall 14-24mm zoom. There are lots of other things that go into choosing a lens, but at these very wide angles, things like autofocus speed are not big points.
That being said, if you’re buying a 14mm lens to be a 14mm prime (and some of you are), then all three of these do very well. Honestly, though, for a little more money you should consider the Sigma 14mm f/1.8 Art if that’s the case. If you’re thinking of matching a 14-24-70mm f/2.8 to collect the whole focal length set, then the Sigma is the best optical choice.
