Besides the shutter speed-priority AE and aperture-priority AE modes, it featured the first fully automatic program AE mode, preset aperture-priority AE, and Speedlite AE mode.

The viewfinder information was also easy to read with a 7-segment red LED readout. The control settings were displayed at the same time which made it very useful.

Besides Power Winder A, developed at the same time as the AE-1, accessories for the A-1 included the compact Motor Drive MA which attained a maximum shooting speed of 5 fps. This Motor Drive had a convenient vertical-grip shutter button. Also, there was the Speedlite 199A which had bounce flash capability.The A-1's body had a fine black finish.
