internal components to rise, as can high ambient
temperatures. Increased internal temperatures can result
in recording times shorter than the estimates shown.

Large image sensor
Cinema-like creative expression is yours
to enjoy thanks to large APS HD CMOS
sensor. This expanded sensor area enables
beautiful background defocusing effects for
a cinematic sense of depth and drama. It
also contributes to extremely high recording
sensitivity that empowers you to effectively
shoot in very dim lighting. Furthermore, when
teamed with manual focus, the sensor lets
you take full advantage of P/A/S/M modes
to manually adjust exposure and achieve
desired brightness and dynamism.
24p cinematic expression
Hollywood films are traditionally
captured at 24 fps, creating a subtle
but unmistakable look that movie lovers
everywhere associate with the cinema.
Simply by capturing your movies at the
same frame rate, in the progressive 24p
format, you can recreate this look and
endow your movies with an added sense
of quality and drama.
Heightened creative potential
You can use Creative Styles and
Picture Effect to exaggerate the mood
or completely transform the look of
your movies. For example, Toy Camera
creates a rough, amateurish look while
Posterization makes a bold statement with
high contrast and vivid colors*.
Interchangeable lens freedom
Interchangeable lenses greatly expand
your moviemaking freedom. Like a
Hollywood director, you can creatively
use whatever lens most effectively brings
out the moment. Whether fisheye, super
wide-angle, telephoto, macro, fixed focal
length or zoom lens, the
a
77 lets you
take advantage of almost any
a
system
A-mount lens ever produced. And because
you can enjoy the benefits of high-speed,
high-precision, phase-detection AF with
virtually all of these lenses, you can
exercise your cinematic creativity without
worrying about difficult focusing problems.
Full manual movie shooting
Full manual operation gives you the
freedom and power to realize your
creative vision. Using manual focus and
P/A/S/M modes (Program, Aperture
Priority, Shutter Priority and Manual), you
can flexibly adjust background blur and
manually control exposure to achieve
desired brightness and dynamism. On-
screen prompts provide assistance to
make full manual operation quick, easy
and comfortable.
Audio noise reduction
Exceptional movie quality is complemented
by outstanding audio quality with minimal
noise. This audio recording quality is made
possible by a high-performance stereo
microphone on the mirror housing and
advanced noise reduction that effectively
suppresses AF lens drive noise via newly
developed NR algorithm.
One-touch movie access
With one press of the Movie button, the
a
77
is ready to roll. The camera immediately
enters movie recording mode regardless of
whether you were shooting photographs
continuously, in single-frame
mode or not at all. It’s the quick
and easy way to capture every
moviemaking opportunity.
Quick AF Full HD Movie
Most interchangeable lens cameras
employ standard contrast-detection
autofocusing when shooting movies. But
the
a
77 delivers the superior speed and
precision of full-time continuous phase-
detection autofocusing, even during
HD movie shooting at 60p—thanks to
the breakthrough advantages of Sony
Translucent Mirror Technology. This newly
enhanced Quick AF Full HD Movie feature
also makes a big difference when focusing
on fast-moving subjects. You can shoot
movies and enjoy wider-ranging creative
possibilities than ever before.
AVCHD™ Ver. 2.0 (Progressive) Full HD
60p movies—a world first

For the ultimate in smooth movie
playback, you can capture Full HD
movies at 60 fps using the new AVCHD
Ver. 2.0 (Progressive) format. This
powerful capability is made possible by
the large APS HD CMOS sensor, which
captures beautiful 1920 x 1080 pixel
movie footage at an accelerated rate:
The same resolution and rate as HDTV
broadcasts

. Moreover, Translucent Mirror
Technology enables Full-time Continuous
AF during movie creation for fast, high-
precision focusing and precise tracking
of moving subjects.
