When Sony took over the system in 2006, 12 lenses were rebranded as Sony A-mount lenses and launched alongside 6 new designs and 2 teleconverters. Lenses were branded as "Konica Minolta" starting in August 2003 following the merger of the two companies. With the introduction of the Maxxum/Alpha 7 and its support for distance-encoded HS(D) flashes in 2001, Minolta began releasing its AF lenses with three additional contacts (eight total) to support the Advance Distance Integration (ADI) functionality, which reports the focus distance back to the camera body. Some of the original lenses were re-released with updated cosmetics and are known as "New" or "Restyled" versions minor optical updates such as coatings and aperture shape were sometimes included. Later lenses changed the grip style and added a rubber coating to the focus ring. Initially, the lenses were equipped with narrow ribbed manual focus rings in hard plastic near the front zoom lenses had a diagonally-ribbed rubber grip.
