The Canon AF35M (sold as the Sure Shot or Autoboy in some countries) is a classic 35mm film point-and-shoot with a a superb 38mm f2.8 lens. Here's how it's described in the Canon Museum:
This was the world’s first Lens-Shutter 35mm autofocus camera at the time. It used a triangulation system with a near-infrared emitting diode (IRED).
The active AF system had the IRED emit a near-infrared beam so its reflection was received by a pin photo diode.
When the shutter button is pressed halfway, the IRED emits a near-infrared beam on the subject. The beam reflected by the subject was received by the pin photo diode. A triangulation was thereby created in the same way as with an optical coincidence rangefinder. The lens draw is adjusted automatically to match the subject distance for focusing. The near-infrared beam also enabled focusing under low-light conditions, making the camera a hit product. The name “Autoboy” became synonymous with AF compact cameras.
This camera requires two AA batteries (not included)
Condition notes This camera was film tested and it produced sharp, correctly exposed negatives. The aesthetic condition of the camera is also good (see photos). The included original case shows some wear (see photo).
Lens: Canon Lens 38mm f 1 2.8. Construction: 4 elements in 3 groups.
Focusing Mechanism: ACTIVE autofocus system.
Shooting Distance Range: 0.9m (3 ft.) to infinity (“).
Filter Thread Diameter: 48mm.
Shutter: Programmed EE shutter. Also serves as diaphragm blades.
Viewfinder: Bright frame finder with parallax correction frame for close focusing. 0.5X magnification. 85% vertical and horizontal coverage of actual picture area. Information includes: Picture frame |1m-“), parallax correction frame (0.9m —1m), autofocus spot, zone-focus scale and index (to check autofocus), camera shake warning/battery check lamp.
