  • SOLVED 300mm F4 Tripod Mount Screw Hole question

    Anyone else with this lens -

    Looking at the tripod mount on my 300mm F4, there is a screw hole on the base plate with no screw in it next to the rectangular recess. I wondered if this is for a detent screw to stop it sliding off a tripod mount or if a screw fell out of it at some point. Does anyone have a screw in there? I know some arca QR plates come with these odd holes for pins / screws etc so maybe something to do with that...but sometimes I find screws fall out of my Olympus gear with usage over time!

    Mine doesn't have anything in there either.
    I also guess it's to add a small cap head to stop it sliding out of some particular Arca type clamp with a slot/groove in it

        I believe it is for an anti rotation pin that is a throw back to when big cameras were carried on tripods and they could come loose. Also to stop rotation on the tripod with rapid panning.

            That hole is to attach the lens to a strap, carrying the camera/lens "sling style".

            Note: some heavy lenses e.g. the 300 F/2.8 have several holes in the tripod foot, which allow to attach a plate e.g. Arca-Swiss or attach a sling style strap. In addition to these holes they also have a pair of eyelets, meant to attach the lens to a strap that you would carry over the shoulder.

            The 300 F/4 does not have these eyelets implying you would have to attach the strap to the eyelets on the camera body, it works but a sling style strap is safer, is more comfortable to wear and offers better operational ergonomy. What I mean is you can have the camera/lens hanging rotated and pointing in the direction you prefer. This way you minimize the time from spotting a subject to having the camera turned on, viewfinder brought to eye and being ready to shoot. Quite often shaving a second or two makes the difference between a great shot and failure.

            Let me know if anything is unclear.

            Cheers Tord
