I took the Canon EOS 5D Mark II on a ride in the redwoods to see if I could shoot some action with it without flash. Although it was too dark to get really sharp photos, I'm pretty pleased with how this came out. I wouldn't have tried shooting at ISO 3200 with any other camera I've tested. It would be cool to do a redwoods mtb shootout with the 5D Mk II and the Nikon D700 to see what they both can do.
