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. The Minolta A-mount system was at first marketed as Maxxum in North America and α (Alpha) in Japan and the rest of Asia. In Europe early Minolta A-mount cameras were initially identified by a 4 digit number followed by AF. The name Dynax was introduced later with the "i" cameras, the second generation of Minolta A-mount camera. It was originally based around a selection of three 35 mm single-lens reflex (SLR) bodies, the 5000, 7000 and 9000. The system also included an extensive range of auto-focus lenses, flashes, a motor drive and other accessories. Compatible equipment was made by a number of third parties. In the following years, many different cameras and accessories were added to the range. The last film-based AF SLRs produced by Minolta were the Maxxum 50 (aka Dynax 30 and Dynax 40) and the Maxxum 70 (aka Dynax 60 and α-70). The Dynax/Maxxum/α branding was also used on two Konica Minolta digital SLRs, prior to the acquisition by Sony (7D, 5D).〔Nakamura, Karen, ( News: Recent top-five camera sales in Japan ), photoethnography.com.

''(Note Dynax digital camera name).''〕 When Sony acquired Konica Minolta's camera technologies in 2006 they chose the "α" brand name (already in use by Minolta in Asia) for their new "Sony α" digital SLR system. The Dynax/Maxxum/α lens mount (which was retained from the old cameras) is now officially known as the "α mount system". ==First generation== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Minolta A-mount system」の詳細全文を読む スポンサード リンク
