Hello,

Apparently I was not paying attention the last time I mounted the lens on the adapter and got it mounted in an offset position. Now I can't remove it from the adapter. Any tips on separating the two, hopefully without damage?

I have the Fotga adapter which may be a similar design... Mine has one tiny screw on the rear and several on the front... Removing the rear wouldn't help much, unless you want to drill the front screws out from the rear. Should be harmless to the lens.

You could also try some oil, but you might have to disassemble the lens and clean it after.

I see the one small rear screw that is on the side of the adapter's rear M4/3 flange. The mount's screws are inaccessible. The screws I see inside the rear cavity belong to the Minolta lens. I peaked in with a flashlight and did not find any other releases other than the one sticking out on the side on the adapter.

Heat sometimes works in situations like these. Put the lens in a freezer bag, or cut the neck off a child’s balloon and put the lens in, adapter side down. Using hot water and a suitably sized receptacle, put the lens (in it’s cover) in, making sure just the adapter is covered by the hot water.
If the expansion caused by the heat is enough, you may be in luck. May not work at first try.

When looking into the rear of the adapter, push the release button on the adapter.
You should be able to see the piece that moves when pushing the button.
Maybe you could use a small screwdriver the pry the locking tab out of its stuck position.

I got it off by exerting more outward pull out as I rotated it and it came out. I checked the alignment and remounted and removed without issue. On looking inside I noticed where the lens flanges and the adapters tension springs were in different positions. It seems that the adapter can be mounted in the wrong orientation but I'm not about to test that theory. I'm going to paint a marker on the side as the only orientation indicator is a tiny red dot on the lens facing side that I would not notice if not paying enough attention or see in dim lighting.

Thank you all for your prompt and helpful tips.
