This adapter is not compatible with Canon Full Frame Cameras or the 650D, 700D. Although the lens will fit physically, automatic diaphragm, auto-focusing, or any other functions will not operate correctly when using this adapter. This is because the lens does not have the ability to have its aperture controlled by the camera body. You can shoot in manual mode or aperture priority mode. For this AF adapter, it does not enable autofocus; it only provides a focus confirmation beep during manual focusing.
