    Assuming that you have tested other lenses:

    Start with a clean white kleenex (not the kind with lotion, of course) and wipe all of the contacts again, changing the surface of the tissue frequently.

    Follow this with a new pencil and its red eraser. Yes, a red eraser is significant. Wipe all contacts again with the eraser, making sure that any possible eraser dust does not get inside the lens. Don't be either too aggressive or too timid.

    If you continue to have issues, try slightly backing off the lens mount rotation, to see if a contact pin has shifted.

    If you continue having problems after all of this then it may be time to have the lens serviced, unless it's the Canon EF 50mm, f1.8. If it's that lens it's probably best to just replace the lens.

    you can replace it (if it's not the STM version) but first try the eraser scrub
