There is a product on Adorama for mounting Nikon lenses to a Canon EOS body: http://www.adorama.com/NVEOSNK.html Has anyone tried this? Is this safe? Is there another product you can recommend that does the same thing? I assume I won't have autofocus or auto aperture, but that's okay because I shoot on full manual anyway. I use a Canon EOS Rebel XTi (the one you guys helped me pick out! ), if it makes any difference.
