The Minolta Maxxum Autofocus Lens System is one of the world’s most complete lens systems, covering every kind of lens from wide-angle, telephoto, and wide-range zooms to large-aperture, reflex, and soft-focus types. Only Minolta Maxxum AF lenses are expressly made to link perfectly with your Minolta Maxxum AF SLR. Every Maxxum AF lens locks into your Minolta camera to form an integrated unit that allows focus and exposure data to flow from the lens’ read-only memory (ROM) integrated circuit to the camera’s central processing unit. Each Maxxum AF lens is a product of Minolta’s advanced computer-assisted optical design. Minolta is one of the few camera makers to insist on making its own optical glass.
The Minolta AF 50mm F/1.7 lens turned in a good performance. The good points are: compact, lightweight, low distortion, quick focusing, low color fringing, and is often found on eBay for just over a hundred bucks for a good copy, (original version), mine is a restyled version, but they’re the same optically according to the specs. The not-so-good points are; very soft corners with a wide aperture, and a sticky focus ring, neither one is a deal killer for the price.
The Minolta AF 50mm f/1.7 is a very good lens but it is slightly inferior compared to its cousins over at Canon or Nikon.
