"The OM40 was released in 1985. It was called OM-PC in some markets.

It has a modified, rubberised body, and is more rugged than the OM 10/20/30, yet cheaper than the OM-2SP. Like the OM-2SP, it has a program mode, an aperture priority automatic mode and a manual mode."

This is about all I know about this camera. It comes from an estate. (Search "camera wiki Olympus om pc" for more info) I put fresh batteries in the camera body and the film advances, the shutter cocks and operates with the shutter release. I also put batteries in the removable power winder (it says "Winder 2" on the top plate) and it also seems to function properly in both single frame mode and in continuous mode at at what seems to be two frames-per-second.

I've only tested it for basic function and cannot make guarantees about metering accuracy, shutter speed timing or any other function. The rubberized exterior shows aging that is typical of many 80's/90's vintage SLRs, with a kind of "chalky" appearance. (See photos.) I know Canon's, Nikon's, Hasselblads, and Mamiya's pretty well but don't know much about Olympuses (Olympi?) although I liked their design and they had an interesting range of lenses when I was learning photography in the '80's

I'm leaving in the camera body batteries I used for testing, but the Winder AA's are not included.

I'll answer any questions if I can. As is, no returns.
