Range of digital SLR cameras manufactured by Sony. They are the successors to the Konica Minolta company that left the digital camera business, selling it to Sony in 2006.

Sony KDL65HX729 opts for the trademark to use the Alpha lens mount type of the same name used by Minolta.

Except for the A900 and A850, these cameras using APS-C format with a factor of the focal length of 1.5 x. Lenses are compatible with its predecessors Minolta autofocus, as well as targeting other brands, such as Tokina, Tamron, Sigma, etc., designed for this mount.

Like the 35mm film cameras, digital SLR cameras are divided into two separate components: the camera body itself, and the target. The latter is an interchangeable device independent of the camera, designed to fill a need the user's scope or coverage angle, or special requirements such as distortion (fisheye) or changing the focus plane (tilt-shift) among others. The target contains, in general, a mechanism for the regulation of light (diaphragm) and a focusing mechanism. The body of the camera contains a mirror, located 45 ° to the plane of the image, whose function is to deflect the rays onto a translucent screen (focusing screen) mate to visualize and focus the image. Usually the light is reflected back to a pentaprism situated above the focusing screen, whose function is to divert the image to the observer and straighten it, since the projected target of upside. At the time of the shot, the mirror flips up and opens the shutter mechanism, to let the light rays directly into the capture device, which is an image sensor in the case of a digital camera.
