One ring adapter with retail package

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
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
