Something is wrong with the lens, your camera, or your settings. You might want to call and talk to someone at Canon before ditching what should be a wonderful lens.
Point taken about calling Canon Support. Will give that a try today before deciding to return the lens. I will say that when i gave up I swapped out the lens for my rf 24-70mm and that worked just fine right from the start.
Anyhow, thanks for the advice and as I said will call canon today.
