Mamiya's M42 SLR — the MSX 1000, TTL averaging metering, mechanical shutter, 1974.
The Mamiya MSX 1000 was a 35mm film SLR made by Mamiya on the M42 screw lens mount. It was the higher model in Mamiya's mid-1970s MSX line, offering a faster top shutter speed than the MSX 500. The MSX series ran alongside the DSX series with a simpler metering setup, and the MSX 1000 was aimed at general and student users wanting a capable, affordable M42 camera.
It is a 35mm single-lens-reflex camera on the M42 screw mount, accepting the extensive range of M42 lenses from many manufacturers. The horizontal-travel cloth focal-plane shutter is mechanically timed and reaches a faster maximum speed than the 500. Metering is TTL averaging with match-needle exposure setting, without the DSX line's spot pattern. Because the shutter is mechanical, the camera fires without a battery, which is used only to power the meter.
This body suits general, student and beginner use and travel where a durable, simple manual SLR is wanted. The M42 mount opens up a wide, affordable lens selection, and the averaging match-needle meter makes exposure setting approachable. Its mechanical shutter and straightforward controls make it a reliable camera for those who prefer to work with minimal electronics.
When buying used, check the mechanical shutter at all speeds for accuracy and capping. Test the meter and confirm the battery type, remembering that meters of this period were frequently built for mercury cells and may read differently on substitutes. Inspect foam light seals and mirror-damper foam for perishing, look for prism haze in the finder, and test film advance and rewind. The shutter fires with a dead meter battery, though the meter needs power; verify M42 lenses thread and stop down correctly.
