Advice to use:
1. With some ring adapters,you have to Turn on 'shoot without lens' to use MF lenses with it.
2. Some Lens can mount, but be careful with retractable lenses whose have protruding rear elements that can come into contact with the mirror of full frame DSLR cameras and damage the camera.This has nothing to do with the design of this adapter. It is a recognised feature of certain lenses and cannot be overcome simply by using a different adapter.
3. 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.
6. For some "AF" adapter, it is didn't mean you can use Auto focus, it only have an indication (bee sound) when you manual focal length actually.
