Sony DSLR-A100, also written Sony α 100, is the first digital single-lens reflex camera (DSLR) marketed by Sony since July 2006. It is derived from the Konica Minolta models of Maxxum/Dynax 5D which Sony bought over. It retains the body design and claimed to have improved on Konica Minolta's Anti-Shake feature.
The Sony DSLR-A100 uses a 10.2 megapixels APS-C size CCD sensor. It also has Eyestart, another feature inherited from Konica Minolta, which provides for automatic autofocus activation by detecting the presence of the photographer's eye on the viewfinder, thus quickening camera response.
The camera also features the automatic vibrating CCD that removes dust each time the camera is shut down. It is sold with a 18-70mm/3.5-5.6 kit lens.
