I got my CE 3! It's quite nice as far as I can tell from a first inspection but you really can't have it all - the asa only goes up to 200. I see now that the CE 2 goes up to 3200. I didn't even think to check.
Also thanks guys for pointing out there are good and bad adaptors, I didn't know and unfortunately had the bad type. I have a knockoff pentax one with the key on the way so basically if I can use my m42 lenses on me ME Super with no focus range issues I don't even need the Chinon, though I'll probably keep it cause no doubt, the way this story has played so far, I'll run into more compatibility issues down the line. ;D
