Canon AL-1

[1][2] Its main feature was the "Quick Focus" focus-assist system[3] that was aimed at those who had trouble focusing through the viewfinder—either novices, or those with poor eyesight—and was intended to head off competition from the first full-autofocus cameras from other manufacturers, such as the Pentax ME F. As a lower-end camera, the AL-1 did not offer a long list of features.

The AL-1 provides focus-confirmation, aperture-priority autoexposure (controlled by a through-the-lens silicon photocell), manual shutter speeds from 1/15 to 1/1000 of a second, and a 10 second self-timer.

An ISO hotshoe, A-series power winder connections, and cable-release socket provide an acceptable level of compatibility with accessories.

The QF focus-assist system uses traditional phase detection linear CCD arrays in the base of the camera.

Due to the camera's lack of features, it was never overly popular and so it would be 1985 before Canon expanded on the concept, even though its competitors raced ahead.
