Attention: Light reflections can also occur with some EOS RF lenses. In this case, the LED is located in the lens and light reflections can occur with long exposure times and / or dark lighting conditions. If EF lenses are used with an adapter on an EOS R camera, there is no problem.
Note: The automatic sensor cleaning function is lost with all cameras. After the conversion, the sensor can be cleaned as usual dry with compressed air or wet with all preparations.
Attention: With the conversion, the sensor cleaning function is lost and *MUST NOT* be switched on again. If Sensor Cleaning is set as a startup action it can cause the camera to fail starting up. I turn it off in the menu, but cannot hide this option. Please be aware that this can irreversibly damage the camera if sensor cleaning is set as a startup action.
