Notice:

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.
"AF Confirm" doesn't means you can use Auto Focus function, it means that it will automatically occur a "beep" sound as an indication while you using MF.
