The A-1 was the top-of-the-line A-series camera. (The AE-1 was the first in this series.) It was a sophisticated electronic camera with all-digital control. 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 the 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.
