Minolta AF lenses where named Maxxum AF lenses in the USA. They all were made for Minolta's autofocus SLR system for 35mm film which was launched in 1985 with the Minolta 7000 which was the first autofocus system camera for the mass market and gave Minolta an advantage in the camera market for several years.

In 2003 Minolta launched the first SAM/SSM-type lenses which have an internal autofocus motor drive instead of being focused by the camera's AF motor. SSM is the silent variant. The Sony α system took over the two conceptions, moving lens production more and more towards SAM/SSM lenses.
New were the following:
- Minolta AF 300mm f/4 Apo G (D) SSM
- Minolta AF 28-100mm f/3.5-5.6 (D)
- Minolta AF 70-200mm f/2.8 Apo G (D) SSM
- Konica Minolta AF 17-35mm f/2.8-4 (D)
- Konica Minolta AF 28-75mm f/2.8 (D)
- Konica Minolta AF 11-18mm f/4.5-5.6 DT
- Konica Minolta AF 18-70mm f/3.5-5.6 DT
- Konica Minolta AF 18-200mm f/3.5-6.3 DT
The last camera of that series was the Sony Alpha DSLR-A100 of 2006. Some call it "the last Minolta". From then the whole system was continued as digital camera system, as Sony α system, i.e. its DSLR and SLT cameras. Sony's system comprises beside common Sony lenses two high-end lens lines, the Sony G lenses and the Zeiss lenses.
