    Default Thread lock on lens screws?

    Hello all, haven't been here for a while

    The bayonet collar on my 14-35 lens keeps working loose, one of the screws has lost some grip which is allowing its neighbours to work loose too. Is it safe to use thread lock on them?

    TIA,
    Thomas

    Yes Thomas, but use the grade that is the least aggressive, and sparingly. If it's Locktight brand it would be the Blue!
    you might also want to check the screws on the tripod mounts of the E-3 and 5 as they are also known to work loose over time when used on tripods
