The Nikon to EOS adapters are all over Ebay and are cheap but the unknown is if the 7D will have a smaller mirror box that the 5D MKII because it is a much smaller sensor. If the area in the mirror box is significantly smaller, I don't know if Nikon lenses would physically fit into the body of this camera. Perhaps someone else knows? My Canon experience is limited to my 5D MKII, all of my cropped sensor cameras are Nikons.
