Pentax MX - 35mm Camera

Pentax MX vintage camera with extra lens. Bought several years ago, used once and worked well, and no issues with developed photos. *Edit: I tested this morning and the shutter does stick at the lower shutter speeds.

The Pentax MX was a 35 mm single-lens reflex camera produced by Asahi Optical Co, later Pentax of Japan between 1976 and 1985. It was Pentax's flagship professional SLR until the introduction of the Pentax LX. Internally, the MX is essentially a smaller, lighter version of the Pentax KX, and otherwise has little in common with the rest of the Pentax M-series. However, the MX was designed as the mechanical twin sister of the remarkably successful entry-level Pentax ME.
The MX was solidly built, and featured a fully mechanical construction, including a mechanical shutter of the horizontal cloth type. Only the light metering system was dependent on batteries. The MX is all manual: it does not feature autofocus or autoexposure modes such as aperture-priority, shutter-speed priority, or full program.
