Found that little camera. I stopped using it when I got my OMD E-M1, it was my first M4/3 camera, I upgraded to an E-PL7 when I found out it had focus peaking (which the E-PM2 does not) and a tilting screen. It was my backup until I got the E-M1 at this point, between the E-PL7 and E-M1, I just did not use it because of the issues mentioned before. It also had a bit of oil or something on the sensor and I just did not bother with the cleanup.
However, since I am on an old camera kick recently and this makes me go out and walk (the experience of using a different camera each time), I found it, spent 15 minutes cleaning that sensor with a swab and sensor cleaning fluid, found a small lens (Panasonic 12-32mm which I have not used since I got the much better, but much bigger G X 12-35mm 2.8) and took it out.
It seems that the sensor cleanup worked as expected, so that's good. I think the only camera like it I have used recently is my Nikon 1 J4 (which is also a low-usage camera for me because of the same issues, no EVF, no tilting screen, no focus peaking). The Nikon might be a bit smaller and focusing is a bit faster, the Olympus has slightly better image quality I think and I think that muscle memory helps, despite the fact that both are lacking in command dials, I am much faster moving around the Olympus and I have a lot of lenses to choose from.
Treating it as a fun, small, cheap point and shoot with an AF lens is really the way to use it, so I will put it back in rotation in that capacity, Probably limit it to the Panny 12-32, Panny 14mm 2.5, Oly 17mm 1.8 and Panny 20mm 1.7 - as they seem to match it well in size.
