Pentax's c.1991 power-zoom compact — 35-70mm f/3.5-6.7, infrared AF, red-eye mode; IQZoom 70-R in the US
The Pentax Zoom 70-R is a 35mm autofocus zoom compact from around 1991, sold in North America as the Pentax IQZoom 70-R. The R in the name refers to its red-eye reduction function, then a selling point. It sat in Pentax's Zoom/IQZoom range of advanced flash-and-zoom compacts that preceded the Espio branding.
The lens is a Pentax 35-70mm f/3.5-6.7 power zoom with seven elements in six groups, offering both continuous and stepped zooming. Active infrared autofocus covers 1m to infinity, with a macro range of 0.6-1m. Programmed auto exposure runs from about 1/5 to 1/250 second plus a bulb mode of roughly 1/2 to 8 seconds, reading DX-coded film from ISO 50 to 1600. A zooming albada-frame viewfinder tracks the lens, and extras include +1.5 EV backlight compensation, multiple exposure capability and the red-eye reduction flash mode.
The stepped zoom, bulb setting, exposure compensation and multi-exposure function give it more creative reach than most early-1990s point-and-shoots, making it a good pick for travel and everyday film shooting where a single do-it-all compact is wanted. The slow f/6.7 tele end leans on the flash indoors.
The camera is battery-dependent and will not fire without power, so confirm it switches on and the power zoom runs the full 35-70mm range without stalling. Test that the flash charges and the red-eye mode engages, check the film door and its seals close cleanly, and run a rewind cycle to confirm the motor transport. Inspect the battery chamber for corrosion from old lithium cells.
