When I shot Sebring this year (Porsche wins!), most of the glass was black. 90% of my friends that also shoot for mags. use Nikon. My friends that were all Canon a few years ago are still smarting over that little lens mounting system trick that Canon pulled. I love the fact that a 30 yr. old Nikkor 50mm 1.2 will still work on my new bodies. Call me crazy, but when a friend sent in his very well used D200 in for service, Nikon totally went over the camera and sent him a bill for $0.00. Would the boys over at Canon do that?
