It was made in the 80s and was one of Olympus's amateur cameras (single-digit numbered OM cameras are the pro cameras, like the OM-1, OM-4T, etc.). I had one for a while. I never really used the Program mode, which was its main selling point, and it ate batteries. A number of Olympus cameras had battery-drain issues. The OM-2SP and the original OM-4 did too. One thing that was neat about the OM-PC was it had a primitive form of evaluative metering that Olympus called ESP. There's a switch to turn it on and off on the side of the lens mount housing. It actually worked pretty well!
