Sony α system
The Sony α system is a camera system which comprises two different autofocus lens mounts.

When Sony took over the DSLR development of Konica Minolta in 2006 it decided to use the Japanese system name α ("alpha") of Minolta's AF mount cameras and lenses since the new Sony DSLRs had the same autofocus lens mount (image of the mount, see Minolta Dynax 9).
In 2010 Sony introduced the Sony α NEX compact digital still cameras for interchangeable autofocus lenses, supplied with the new Sony E-mount which they share with Sony's flagship NEX camcorders. The Sony α NEX Camera Mount Adapter's first version allows mounting most Sony α system lenses but not most of the old Minolta α system lenses: it only accepts α lenses with internal autofocus motor-drive. The second version even allows to use most old Minolta AF lenses in autofocus mode.
The Sony α33/α55 "SLT" cameras (single lens translucent cameras) proved that the old Minolta AF mount is also good for smart non-DSLR digital system cameras. But some of the old lenses once designed for the Minolta AF mount won't work with the SLTs, especially not with lenses made by Sigma.

The NEX cameras proved that compact digital system cameras with APS-size image sensor are no bad idea.

Sony continued Konica Minolta's tradition of marking its high-value autofocus lenses as G lenses, except the lenses constructed by Zeiss.
The α lenses can be used on the old Konica Minolta DSLR bodies.
