Does anyone have experience with the Canon EF 400mm f/5.6 adapted to the R5 (or R6, R6ii, etc)? If so, what has been your experience? For the price it seems like pretty good bang for the buck if you don't mind using the adaptor.

    Excellent Beginner's Camera, and a Very Good Enthusiasts Camera
    The R50 is a fine entry level/beginner/casual stills camera. It is not a pro level camera, but would be fine for hiking, street, family photos...
