I dunno, I currently own the M50/1.7 and have had both on my camera (Ricoh XR7) back in the day. The M50/1.7 is almost twice the length (31mm vs. 18mm) and while the M40/2.8 has both aperture and focus rings, both are a pain to use in the field due to the cramped real estate. The M50/1.7 OTOH, is a nice handling lens. I don't know much about they Chinon except that it is supposed to be slightly larger than the Pentax according to a photo.net post from a couple of years back (

In a few short words, except for making a pocketable combo on the MX and other small bodies such as the Super Program, I saw no incentive to ownership at the time...too tiny. That being said, if I had an MX, I might well look for the pancake just for the kick of it since the lens is a part of representative kit for the camera.
