What are the lens links for Canon's SLR?

Answer:

All the cards are the same, only the sub-Canon interface, Nikon bayonet, which is generally other brand lens, do the time, will speak, but absolutely no Nikon original lens, is the Canon bayonet, just like you go Unicom, China Telecom charge mobile phone calls, obviously want to hit people places.
For non-full-size machine, only EF lens, but not the whole frame can be used in two kinds of lenses (only the full-frame lens used in non-full-time lens when the actual focal length to wind 1.6 this coefficient). Such as: EF17-40MM This full-size lens used in your 60D on the actual focal length is 27.2-64 mm, the equivalent of wide-angle shrink! )
