Sigma takes the prize, currently, with their 8-16 UWA-Z. Others in this category, include the Tokina 11-16, and 11-20, the Tamron 10-24 models, and the other Sigmas, plus all the proprietary ones. Which of these do you think - overall - does the best job on extreme Wide Angle shots? What are the deficits, using them?
Ultrawides are pretty specialized lenses and only a relatively small percentage of photographers are actually successful using them. Lots of anamorphosis, complex distortion, uneven brightness across the frame, etc and a completely unrealistic perspective. I prefer to use a longer lens and simply stitch images for wider views. Most of the deficits come from shooters not fully understanding how to make good images with them.
