I have one of these unbranded types (see here: Canon EOS EF lens To Micro 4/3 m43 Adapter 4 GF1 GH1 G1 | eBay (http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=190472137871) )

and I cannot for the life of me remove it from the lens it is attached to. There's what appears (see pic at link above) a worthless pin that sticks our from the side of the adapter, but it seems to do nothing.

Any help would be appreciated!

If it works like the two I have, you should be able to move the pin down (toward the camera) to release the adapter so that you can turn it, thus allowing you to remove it from the lens.

Kevin, thanks. I kept trying to push it in, to no avail! I couldn't believe how simple it was after I read your post. Thanks again!

Ahhhh Jeff..... you weren't the only one to make that mistake..... :-)

I had considered taking some channel locks and getting medieval on it, but common sense prevailed. I had read on some sites months ago of guys cutting them off.

Chip you tried out your Fisheye yet? I put mine on this evening, it is pretty cool.
