Michael Rogers member since: 12/2/2003	Rating: 4 out of 5 Got this Lens the Sigma 800mm December of last year. I mainly use the lens for SurfPhotography. So I've been shooting a shutter speed at 1000, ISO 400, in the Tv mode with a Canon 10d. With a Wimberly head its a breeze to pan, with a "three-way pan head" it's a nigthmare. Image Quality is quite sharp with a more than tolerable depth of field. You can fill your frame with your subject from a long ways off. I like getting the expressions of my wave riders faces. I give it an eight because of the f5.6 stop makes it to slow after sundown....It would be perfect at f4...hahahah 2/8/2004 3:26:56 AM
