I am a working credentialed freelance photo/video journalist in the Los Angeles area.
I recently covered the Protest March and shot it entirely with the Canon T2i, both video and still.
Quite lightweight, easy to use, unobtrusive. Overall quite happy with result.
As posted elsewhere, best results with L lenses.
This was shot primarily with 70-200 2.8 IS version 1, also 10-22 lens.
Images have a slight washed out look, might have benefited from a ND filter, but didn't have one with me.
I have been using camera slr and video cameras for years.
