    I have a Nikon-m43 adapter which is very firmly stuck to a Sigma zoom lens with Nikon mount. Or, in other words, I am unable to remove that adapter from the lens.

    The adapter is a Big_is Nikon AI F Lens to Micro 4/3 M4/3 Panasonic G5 GF1 GH1 Mount Adapter ( and the lens is a very old Sigma 100-300 AF/APO (pictures at - I am not the one selling, just linking for the good photos of the lens).

    I am looking for any and all suggesting on how to remove the adapter from the lens.

    Many thanks!

    /me blushes in shame.

    Google has come to the rescue, as always - but this time only on the second attempt:

    The magic is to look at this strange button / screw that stick out of the mount. And instead of playing the screw / unscrew game, it needs to be used as a lever and pushed away from the camera side towards the front of the lens.

    This then unlocks the pin and Life Is Good Again.
