Ensure the lens firmware is up-to-date if applicable. Clean the lens contacts on both the lens and the camera body. Try shooting in better lighting conditions or select a clear contrast point for the AF system.

Check that the lens is fully seated on the mount. Clean the electronic contacts on both the lens and camera body with a dry, lint-free cloth. Try updating your camera's firmware.

Ensure the lens is properly focused. For optimal sharpness, especially at the edges, try stopping down the aperture to f5.6 or f8. Clean the lens elements.
