All three shots below were taken at aperture of F/2.8 (gotta love a fast lens) and handheld off-camera flash was used - also gotta love the on-board master flash controller of the 7D. I also shot some hi-def video (yes, 1920x1080x30 - yikes!), but there's no easy way to upload/view that via the web, plus it's nothing great ... although the clarify is quite impressive given the low light. Processed via CS4/ACR and click on the images to see the full-res versions - the Canon 7D did quite well IMHO.
