The Canon AL-1 was a new type of manual focusing SLR. It had a through-the-lens focusing aid, that means the same type of distance CCD sensor as later used by autofocus SLRs. The camera was introduced in 1982 by Canon. In 1984 the camera was marketed as "official product" of the Olympic Games in Los Angeles.
As a modern SLR it also has exposure aids: Shutter speed and aperture setting aided by match-needle instrument of TTL meter, or shutter speed controlled automatically by the meter. The instrument is visible through the pentaprism finder, as are the focusing control LEDs. The green LED between two red LEDs indicates correct focusing of the middle of the image.
