Comment:

The new #1 in the Ultra Wide Zoom category, easily surpassing the highly regarded Nikon AF-S Nikkor 14-24mm f/2.8G ED. However, while pushing the focal length boundaries at the wide end is commendable, the results are somewhat disappointing. Center performance remains good at 11mm, but corner performance is poor, with very strong vignetting, pronounced LaCA and low resolving power and contrast. Stopping down marginally improves the situation with maximum resolving power being achieved at f/7.3, but corner performance remains unimpressive. Having said that, it is important to remember that other lenses do not go to 11mm at all. The way to look at it is that this is by far the best zoom lens in the 14-24mm range, with the option of occasionaly shooting at 11mm when corner performance is not that important. Highly recommended.
