Hello, this is my first post here. When I am googeling about lenses most of the time I end up here. 
I just received a nice Biometar 80/2.8 and wanted to try it out with my P6 to 4/3 adapter. That adapter is now on my CZ Sonnar 180/2.8.
The problem is I can't get it off.
I don't want to put to much force on it. Is there a thing I forgot or should know about?
Any ideas?
Thank you, Michiel |

Make sure you're twisting the retainer ring the right way. Lookin from the FRONT of the lens, the ring needs to turn counter clock-wise. It was probably tightened too far the other direction. You just need to use a lot of force. Good luck

I am still not sure. When I take of the lensmount cap from the Biometar I have to turn it counterclockwise when i look at the lensmount side.
Should I do not the same to take of the adapter?
Thanks for your quick replys |

So the quick answer is that the threads are reversed. Turn opposite direction than is intuitive.

Michiel, As rawhead said, when the mount end of the adapter is facing you, the locking ring has to turn clockwise to unlock. When the front element of the lens is facing you the ring is turned anticlockwise to unlock. It sometimes takes a lot of force.

Thanks a lot, now I know for sure. At first the info was a little confusing.
I have to go to my studio and use a tool (in cloth) to get it loose.
Me, always opening every jampot for the ladys 
The thing is really glued on it right now.
Now I have to wait till saturday. No time.
I will post some pics with the lens, if I ever get it of.
Merci, Michiel |

These adaptors seem to almost friction-weld themselves on if they're tightened just that little bit too much. It will come off - try a rag soaked in hot water and squeezed dry.

try to use an oil filter wrench, you can get it at most hardware stores.
Note: get one that is using a rubber band.

Looks like a cheap Chinese-made adapter as it is very similar in looks to my (now discarded due to low quality) P6->m42-adapters.
I had similar problems and then realized, that I was turning the ring to the wrong direction. Looking from the side of the adapter one should turn clockwise, ie. the opposite direction to what feels intuitive.

I got one (but left it in China) from a hardware store. Most important is to get one with a rubber belt.

Thank you all, I got it loose.
Finally did it with a grip I use to tighten pieces of glewed wood together.
Must have tighten it further and further because I forgot it turns the opposite derection.
One of these days I will post some pics with my won Biometar as a reward (I hope )for your help.

Great news! OK, now's the time to put a mark on the knurled locking ring in line with red dot, so you can see which way it needs to be turned
