The joy and pain of a wide angle adapter

So I got hold of a Schneider / Century Optics Fisheye Adapter for my Z1 camera. I've used it on a few shoots so far and it's been great. Yesterday however I managed to put the thing on wrongly. You have to match yellow dots - and I matched the wrong ones and I don't know my own strength and the result is I now have a permanent adapter fixed to my camera. I'm hoping somebody somewhere can fix it. Fingers crossed.


UPDATE: Alan at PEC on Dean Street and Debbie managed to get the thing off. Thank you. ! was abusing the thing and not putting it on properly. I have learnt my lesson. I hope.
