This lens mount adapter allows Nikon F (F, non-AI, AI, AIS, AF, AFD) Mount Lens to fit on Canon EOS camera body. Although the lens will fit physically, automatic diaphragm, auto-focusing, or any other functions will not operate correctly while using this adapter. In this case "stop-down mode" will need to be used when metering since the lens does not have the ability to have its aperture controlled by the camera body. You can shoot with manual mode or aperture priority mode with EOS body. Infinity focusing is guaranteed. The Nikon F to Canon EOS version 2 lens mount adaptor has a rear push button style lens release lock and tighter contruction tolerances.\n\nCompatible Cameras (not limited to the list, as long as the body takes a Canon EF lens)\nCanon EOS 1D, 1Ds, Mark II, III, 5D, 5D Mark II, 10D, 20D, 30D, 40D, 50D, Digital Rebel XT, XTi, XS, XSi 300D, 350D, 400D, 450D
