Ricoh's 1989 AF zoom compact — 38-76mm f/3.5-6.7, infrared AF, DX coding, 2CR5 power; aka Shotmaster Zoom.
The Ricoh RZ-750 is an autofocus zoom compact for 35mm film introduced in 1989, an early entry in Ricoh's RZ zoom series. It was also marketed under other names in some regions, including Shotmaster Zoom and TF-900 Zoom, and a Date version with a quartz databack was common. It should not be confused with the twin-lens Ricoh TF-900 or the later RZ-800.
It carries a 38-76mm f/3.5-6.7 zoom of 7 elements in 6 groups, focused by active infrared autofocus from 0.68m to infinity. The programmed electronic shutter spans 3 seconds to 1/500, exposure is fully automatic, and DX coding reads ISO 64-3200 film. A built-in flash offers red-eye reduction and a night mode, there is an electronic self-timer, and film handling is fully motorised. Power comes from a single 2CR5 lithium battery, with the body at roughly 140 x 74 x 59mm and 365g.
As a chunky early zoom compact it suits shooters who want a simple all-automatic film camera with a bit of framing flexibility, the 76mm end being handy for casual portraits. It is bulkier and slower-lensed than 1990s Espio-class rivals, which keeps prices friendly.
These are fully battery-dependent, and the 2CR5 cell is pricier than AAs, so confirm the camera powers up, zooms and fires before buying. Test the flash charge and red-eye lamp, listen to the motor wind, and check the databack on Date versions if you care about it. Film-door seals and a clean AF window round out the checks.
