This is a manual adapter, so lens functions that rely on electronic communication with the camera body (autofocus, AE metering, image stabilization, etc.) will be disrupted.

Set your exposure manually or meter using your camera's Aperture Priority (stop-down) mode.

If your lens does not have a manual aperture control ring, it will stop down to its smallest f/stop by default.
