When introduced, the Sigma
10-20mm was the widest lens in production for APS-C sized dSLR cameras.
This review is specifically about my copy of the lens, others
experience may differ because Sigma is notorious for poor quality
control. When it comes to action sports, or anything involving people,
a lens this wide is hard to use well. While technically non-distorting,
as is the nature of ultra-wide angels, anything at the edge of the
frame is distorted. The unique view can give a great perspective, if
you can get close enough to your subject. Out of the box the lens comes
with caps, a lens hood and a soft padded bag. Sigma's rear caps are ok,
but the front cap on this lens is antiquated. It is not of the center
pinch variety, you can't attach or remove the cap with the lens hood
on. Build quality is good, better than Nikon's consumer range including
the more expensive 18-200mm VR. Many don't like Sigma's matte black
finish, personally I have no issues with it, finding that like the rest
of the build quality it falls somewhere between Nikon's pro offerings
and kit lenses. This lens zooms in the same direction as a Nikon, which
is nice because not all Sigmas do.

Note how long and skinny the Jefe is due to distortion.

Let's take that distortion a bit further. Ugh. To me this type of
distortion is just unpleasant.

On select occasions, ultra-wide fits the scene. Garrett Brown runs
