  • HELP! Sticking lens hood

    It is becoming increasingly difficult to turn the lens hood on my ZD 12-60 SWD into and out of the 'locked' position. I've carefully cleaned the hood and the lens where these parts interact - but to no avail. There doesn't appear to be any distortion of the plastic in these areas.

    Please can anyone recommend whether there is any kind of lubricant that improve this situation which will not cause any chemical or other damage?

    Thanks in anticipation.

    You probably want a dry silicone lubricant, applied by first spraying onto a tissue then carefully wiping onto the hood's bayonet. Plenty available through Fleabay.

      The best solution for sticking lens hoods IMHO is graphite, ie. soft pencil "lead".

      Hope this helps.

        I would go with Stephen; graphite can be abrasive and dusty and can leave black marks on your hands.

          That's my method & it works quite well (& long lasting).

          Also, it is wise to deal with this ASAP as I have heard of the front being sheered off the 12-60 lens because of this. Mind you, the person it happened to must have been a little less than gentle in the process.

            I've used dry silicone spray as Stephen describes for years on my lens hood bayonets and the zoom barrels of all my lenses. It works a treat and I don't wish for anything better. I'd be prepared to bet that Olympus use a silicone treatment during assembly of their lenses - new lenses have the characteristic silky/slippery feel of silicone treated surfaces.

              I've read that facial oils transferred to the interfacing parts can alleviate the situation.

                Thanks to everyone for the advice - I'll get some dry silicone spray.

                  Don't forget to wipe the zoom barrel with a treated tissue. It will prevent sticking and damage to the rubber seal. It brings the zoom action back to new.

                  The water repellent properties of silicone also prevents capillary action allowing water to creep past the seal.

                    Jim,
                    Thanks. I've applied some dry silicone spray on a tissue and the lens hood locking/unlocking is now greatly improved.

                    In the process I found that the problem area wasn't the 'pegs' etc. on the bayonet - but actually on the inboard circular face of the lens hood where it butts up against the lens.
