Do you guys think a Nikon Micro-Nikkor - Macro lens - 105 mm - f/2.8 G ED-IF AF-S VR - Nikon F, would fit on a Canon Digital Rebel XTi 10.1MP DSLR? I know that the lens is EXPENSIVE, but I dont plan on buying it YET, I have to save up the money first, but This is a lens I would LOVE to have. But I dont want a Nikon! OR do you guys know of any Cannon DSLR lens's similar to the Nikon Micro, around the same price or cheaper??
