α mount system or Alpha mount system may refer to:
The Minolta A-mount camera system was a line of photographic equipment from Minolta. The system used a lens mount called A-mount, with a flange focal distance 44.50 mm. The new mount was larger than the older SR-mount making old manual lenses incompatible with the new system. The mount is now used by Sony, who bought the SLR camera division from Konica Minolta, Konica and Minolta having merged a few years before.

Sony α100 (DSLR-A100) is the first digital single-lens reflex camera (DSLR) marketed by Sony. It is successor to previous Konica Minolta DSLR models through Sony's purchase of the Konica Minolta camera division. The α100 retains similar body design and claimed improvements on Konica Minolta's Anti-Shake sensor shifting image stabilization feature, renamed Super SteadyShot. It uses a 10.2 megapixels APS-C size CCD sensor. Another notable feature inherited from Konica Minolta is Eyestart, which provides for automatic autofocus activation by detecting the presence of the photographer's eye on the viewfinder, thus quickening camera response.
