Pentax Super A
Pentax introduced the Super A (or Super Program in North America) in 1983. It was accompanied by a new line of Pentax-A K mount lenses, whose "A" lock on the aperture ring permitted the body to set the f/stop for programmed and shutter-priority autoexposure.
The Super A offered a wide shutter speed range of 15 to 1/2000 seconds, and accepted an external winder. Shutter speeds were selected electronically by using rocker buttons on the top panel, a method adopted from the ME Super.
The Super A was followed in 1984 by the related Program A/Program Plus—a less expensive model, which omitted the Super A's top LCD and 1/2000 second shutter speed.
