For some ring adapters, you may need to enable 'shoot without lens' to use MF lenses. 2. Some lenses can be mounted, but exercise caution with adjustable lenses. 3. While the lens fits physically, automatic diaphragm, autofocus, or other functions will not operate correctly with this adapter. In this case, 'stop-down mode' must be used when metering, as the lens lacks the ability to have its aperture controlled by the camera body. You can shoot in manual mode or aperture priority mode. **Package Content:** 1 x Adapter Ring (other accessories shown are not included).
