The Sony Alpha DSLR-A100 is the initial Sony-branded DSLR release after cooperation between Konica Minolta and Sony which began in autumn 2005. In winter 2005/2006 Konica Minolta decided to hand over all its assets related to DSLR technology to Sony.

The Alpha A-100 is Sony's first product in the modern SLR segment. It is the successor of the Konica Minolta Dynax 5D which had a similar antishake system introduced to DSLRs in Konica Minolta's 7D (initially introduced in Minolta's DiMage A1 "bridge" digital camera). The digital capture sensor is placed on the antishake-mechanism. The camera doesn't need special antishake lenses because shake-compensating movements are done by the sensor. All lenses for Minolta's 35mm autofocus SLRs can be used on the Sony camera body - the lens mount is Minolta's 1985 A-mount/Alpha-mount bayonet. A dust removing system helps to keep the sensor clean.
