The α mount (or Minolta AF mount or A-mount) was introduced with Minolta's first popular fully automatic autofocus single lens reflex camera Minolta 7000. It is a bayonet lens mount with three main components: The bayonet, the set of electrical contacts, and a rear engagement to couple the camera's lens focusing motor drive with the lens's focusing mechanics. The introduction of the Minolta 7000 in 1985 was a historical step to fully automatic SLR systems for the mass market.
There were some main product generations. The first were the original AF camera body series and the i-series bodies. These were followed by the xi-series bodies which could use the xi-lenses with internal zoom motor drive. The suceeding camera models tolerated the xi-lenses but didn't support their zoom motor. The last generation of analog SLR bodies supported lenses with own internal focusing motor drive (SAM micro motor lenses or SSM ultrasonic silent motor lenses).
The G-lenses became Minolta's series of superior camera optics. The series was continued by Sony when the Japanese electronics giant took over Konica Minolta's SLR development and production assets. Zeiss supported Sony by creating further top-quality α lenses, the ZA-lens edition. In its first 4 years the Sony α system was just a continuation of Konica Minolta's DSLR concept. For the following 4 years 2010 - 2014 it was modified by replacing the DSLR concept by Sony's own SLT concept. But probably the system's second bayonet, the E-bayonet introduced in 2010 for the Sony NEX series of handsome mirrorless digital system cameras and for professional Sony camcorders, will replace the original α mount completely except on the available A-mount/E-mount adapters.
