Approximately 0.05 second minimum release time lag
Accelerated shutter response lets you
capture decisive moments with confidence.
An innovative electronic front curtain
shutter in the image sensor slashes shutter
releasetimelagtoaclass-leading0.05

and vibration than a mechanical front

12 fps continuous shooting
(
in Continuous Advance Priority AE mode
)
Every second, you can capture up to 12
images with clarity and precision at full 24.3
megapixel resolution. Moreover, you can
enjoy the expressive power and flexibility
of interchangeable lenses without slowing
down performance. As with full-time
autofocusing, this extraordinary response
is made possible by innovative Sony
Translucent Mirror Technology.

Full-time Continuous AF
Accelerated full-time continuous phase-
detection autofocusing keeps your subject
sharply focused at all times. Even at
maximum continuous shooting speed and
during live-view movie shooting—thanks to
revolutionary Translucent Mirror Technology—
you can clearly capture sports action
and fleeting facial expressions without
resorting to manual focusing. The supreme
speed and precision of phase-detection
autofocusing is faster and more precise than
thecontrast-detectionAFsystemsemployed
bycompetingcameras.Itletsyoueffortlessly
capture dramatic moments in all types of
situations with professional-looking results.
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.
