(詳細はMinolta and Konica Minolta released the following lenses for Minolta A-mount cameras between 1985 and 2006. While most auto-focus lens designs were new developments, some optical constructions were derived from Minolta SR-mount lenses (as indicated). When Sony took over the system in 2006, 18 lenses were reintroduced as Sony A-mount lenses. Of those, most lenses are optically, mechanically and electrically identical to their Minolta predecessors and differ only in their outer appearance, however, three have seen subtle changes in the optics and electro-mechanics. All Minolta and Konica Minolta A-mount lenses are compatible with Sony A-mount cameras. Up into the mid 1990s, A-mount lenses for the North American market (where the A-mount camera bodies were labelled ''Maxxum'') were engraved ''Maxxum AF'' rather than just ''AF'' (as was used in the rest of the world, including in those regions otherwise using the ''Dynax'' and ''α'' labels for the cameras). Although some buyers associated either the ''Maxxum AF'' or the ''AF'' designation with a higher quality, both types of lenses were built to exactly the same specifications and quality standards in the factory, and were only used to improve trackability and dry out the gray market. They differed only in their name plate and part numbers ( ????-1?? for ''AF'', ????-6?? for ''Maxxum AF''). A similar scheme had been used by Minolta in the 1960s and 1970s with their ''Rokkor'' and ''Rokkor-X'' SR-mount lens designations. The ''Maxxum AF'' lenses introduced in 1985 originally used a "crossed XX" font, which was soon dropped by Minolta after a trademark lawsuit with Exxon.List of lenses: ==See also== * List of Konica Minolta A-mount lenses * List of Sony A-mount lenses * List of Minolta A-mount cameras * List of Konica Minolta A-mount cameras * List of Sony A-mount cameras * List of Minolta V-mount lenses * List of Minolta SR-mount lenses 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「List of Minolta A-mount lenses」の詳細全文を読む スポンサード リンク
