    Default 1.4 x Tele problems

    Notice twice it has failed to lock to the lens, I add it to the body first then to the lens, twice as I moved the camera I noticed luckily it rotated and wasn't locked to the lens, anyone had similar and did you lubricate the pin? it can be locked by operating the slider button back and forth, but I do not want to miss it one time.

    Never had that problem, but I always mount a teleconverter to the lens first and ensure it's locked.
    Please don't ask about my kit, it's embarrassing!

    Yes I realise that is the correct way of doing it or the camera can sense what's on it incorrectly, but I often do it in the field and like to get the camera sealed up first, as the 500 and tele is a bit wieldy to mount to the camera. its the pin in the converter that is the problem, so fitting it to the lens first would make no difference to the problem.

    It does help in the sense that having locked it, I always give a quick twist as a double check.
    I take the view that lens security is more of an issue than the potential of a bit of dust, but completely accept that a 500mm is more than a little unwieldy. ;)
    If you do decide to lubricate the pin, go easy, and I would probably use graphite to do it.
