Olympus T2 Adapter ring stuck on my Sony Alpha — how can I get it unstuck?

Question

Edited. I bought a Samyang 500mm Mirror lens off ebay so that i could try and expirement with tele photos before i decided to buy really expensive lenses..

I got the lens with a T2 Adapter (Olympus) Written on it [Edit-This ring is about 3mm to small for the Sony Alpha and the flanges are shorter- so it slips past the locking mechanism and 'gets stuck' in the void..]

which i screwed on to this side of the Lens [Edit- Cheaper than other.. but a bit of practice and get nice photos.. for the price ;) ]

[Edit - I was doomed from the start.. The auction is misleading in its words and meant you can buy an adapter but they make it sound as if one fits all- or the correct one is included- buts its not.fine print]

As usual I aligned the red dot the the Alphas red dot- put it in and screwed clockwise.. a bit unusual at first as it rotated about 1/4 around.. and my other lenses only twist and lock quickly..

I did not make anything off it and started experimenting and taking photos all looks OK.

Then when i try to unlock the lens anti-clock wise.. I realised there is play- that its not actually locked in properly... and there is about 1/2cm play either way on rotation and I cannot remove the adapter :( The actual lens screws of the apter ring but the ring stays in :( I press the release button and nothing- it wont turn any further.. I tried slight force and nothing. wiggling it up down-.. it stuck - but loose.

Can anybody advise how to remove the damn ring.. is there a a release inside the barrel somewhere? can i unscrew something to get to the mechanism.. I know the mirror need to be untouched and work in a dust free environment.

Surely i am not the only plonker that has done this.. I actually ordered the correct adpater now.. but the original sale description says this

Answer

Well, in the link you posted the Pentax forum, the guy mounted the lens back on the camera for extra grip and slowly applied force and it eventually came off - so there's that option...but...

The safest option is going to be to take it to local place or send your camera in to have it removed. If you damage the mount while trying remove it yourself through force you could end up spending quite a bit of money.
