Translucent Mirror Technology

Sony Translucent Mirror Technology

revolutionizes interchangeable-lens

photography by enabling simultaneous

focusing and image capturing on a

full-time basis. Unlike competing cameras

that swing a mirror to either direct light

toward the AF sensor or the image

sensor–one at a time, the a77 continuously

directs light to both sensors simultaneously

via a stationary translucent mirror. This

breakthrough enables leading continuous

shooting speed, accelerated full-time

continuous phase-detection autofocusing—

even while shooting HD movies–and

smooth uninterrupted live-viewing on the

finder and rear monitor during single shot,

continuous and movie shooting. Quite

simply, Translucent Mirror Technology

significantly improves overall performance

and leaves the competition behind.

sensor as of August 2011.

Notes:

Continuous shooting speed may be slower depending on

shooting conditions. In Continuous Priority AE Mode, the

aperture is fixed at F3.5 or the maximum aperture of the

lens, whichever is smaller. Continuous shooting speed

( fps ) lowers when high ISO NR function is On.
