Olympus's dual-lens 35mm AF compact — the AF-1 Twin, two focal lengths, splash-resistant, 1988.
The Olympus AF-1 Twin was a 35mm autofocus compact camera by Olympus, released in 1988 as a dual-focal-length point-and-shoot in the weather-resistant AF/Infinity line. It was the equivalent of the Infinity Twin sold under a different name in some markets, and it developed the original splash-resistant AF-1 by adding a second lens focal length.
It is a full-frame 35mm autofocus camera exposing standard 24x36mm images, not half-frame. Rather than a zoom it offers two fixed focal lengths, a wide and a longer view, switched by the user, with active autofocus and programmed automatic exposure reading DX-coded film speed. A built-in flash is fitted, the body resists splashes, and the camera is battery-dependent with no manual exposure mode. The finder reframes for the selected focal length.
The two-lens arrangement gives a choice of framing without extra gear, suiting travel, general and street photography where flexibility helps. Automatic focus and exposure keep operation simple, and the sealed body copes with outdoor conditions. It suits a photographer who wants more than a single-lens compact but values point-and-shoot ease over manual settings.
When buying, inspect the battery compartment and contacts for corrosion, since leakage is a common fault in these AF compacts, and note there is no selenium cell to fail. Confirm both focal-length positions switch and focus correctly, that the flash fires and recycles, and that autofocus locks. Check both lens settings for haze and fungus, test the film-door light seals, and verify the frame counter and film transport work.
