    Canon EOS R
    EF to RF Adapter

    My camera will be working fine then the touch screen will stop functioning and I cannot preview my images. I have tried turning the camera off and on, removing the lens (and adapter), and taking out the battery. Then the next time I go out to shoot everything works perfectly. I have had the contacts cleaned and bought a new EF adapter, but last night the problem occurred while using my RF lens.

    It's frustrating to not know if I will be able to change my focus point or see what I have shot.

    You may want to call Canon customer support, if the screen is cutting in and out of working it sounds like an electrical issue and may need them to service it.
