One thing is for sure…I enjoy using my wide angle lenses during crits.  Yesterday, I spent most of the day using my Sigma 17-70mm f/2.8-4.5 paired with the Canon 7D.  During the Sugar Land Crit, I pretty much used the Canon 10-22 f/3.5-4.5 with the Canon 40D.  Whole different perspective when looking through an ultra wide lens (10-22mm) and a wide lens (17-70mm).  Here’s one shot from yesterday’s Houston Grand Crit taken at the second right hand turn.

Exif info: Canon 7D, Sigma 17-70mm f/2.8-4.5 @ f/4.0, 1/2500, 17mm, ISO 800, AI Servo Mode.
