Ultrawide Portraits with the Sigma 10-20

This is a hands-on review of the Sigma 10-20 f/4-5.6, an affordable ultrawide lens for crop sensor cameras.

This lens has been around for a couple of years and has already been reviewed in detail in several websites.  If you would like to know how about its sharpness, distortion, chromatic aberration and so forth, check these reviews:

• DPReview including their lens comparison tool.
• Photozone (Canon version here and Nikon version here)
• Thom Hogan

Instead, this review will focus on what it's like to use this lens in the field, particularly for people photos.  In Part 1 of this post, we'll have a look at some of the ways an ultrawide can be used for shots of people.  In Part 2, we'll discuss some characteristics of ultrawides to make better use of them.  In Part 3, we'll talk about the Sigma 10-20.
