Olympus's dual-lens 35mm AF compact — the Infinity Twin, two focal lengths, program AE, 1988.
The Olympus Infinity Twin was a 35mm autofocus compact camera by Olympus, introduced in 1988 as a dual-focal-length point-and-shoot. It was closely related to the Olympus AF-1 Twin sold in other markets, and it extended the weather-resistant Infinity/AF line by offering two switchable lens focal lengths in one body rather than a zoom.
It is a full-frame 35mm autofocus camera exposing standard 24x36mm images, not half-frame. Instead of a zoom it provides two fixed focal lengths, a wide and a longer setting, selected by the user, with active autofocus and programmed automatic exposure reading DX-coded film speed. A built-in flash is fitted, the body is designed to resist splashes, and the camera is battery-dependent with no manual exposure mode. The optical finder adjusts framing for the two focal lengths.
The two-lens design offers a choice between a wide view and a tighter one without carrying extra equipment, which suits travel and general photography where framing flexibility is useful. Automatic focus and exposure keep it simple to operate, and the sealed body handles outdoor use. It suits a photographer who wants more framing options than a single-lens compact but prefers point-and-shoot ease.
When buying, check the battery compartment and contacts for corrosion, as leakage is a frequent problem in AF compacts of this era; there is no selenium meter to fail. Confirm both focal-length settings switch and focus correctly, that the flash fires and recycles, and that the autofocus locks. Inspect both lens positions for haze and fungus, test the film-door light seals, and verify the frame counter and film transport operate.
