An abundance of smart, versatile features
Auto white balance
1200-zone Evaluative Metering
High-precision metering ensures balanced
exposures in wide-ranging lighting
conditions. This precision is made possible
by the extremely high resolution of an
advanced evaluative metering sensor with
1200 zones. The sensor accurately meters the
light and color of image data transmitted
directly from the image sensor and can
also recognize wide-ranging subjects and
shooting situations. The amazing density
of this 1200-zone meter contributes to both
highly precise metering and accurate
subject recognition. The Fn (Function) button
lets you choose between Multi segment,
Center weighted and Spot metering modes.
Exposure mode
Selecting an exposure mode is as
simple as rotating a dial. Conveniently
located on top of the a77, the clearly
labeled mode dial provides quick and
direct access to Program Auto, Aperture
priority, Shutter-speed priority and
Manual exposure modes, as well as a
fully-automatic Auto mode and 8 Scene
Selection modes (Portrait, Sports Action,
Macro, Landscape, Sunset, Night Scene,
Hand-held Twilight and Night Portrait) that
apply optimized AF, drive mode, exposure,
brightness, contrast and other settings
appropriate to each type of scene.
Face Detection and Face
Registration
Capture people beautifully with the a77,
thanks to advanced Face Detection
technology that instantly detects up
to eight faces and optimizes shooting
parameters to ensure accurate focus
and skin tones even when recording
movies. Smile Shutter
™ technology can
automatically release the shutter when
subjects smile and offers three sensitivity
levels as well as a smile level indicator
that is displayed when the mode is
active. A Face Registration function also
lets you register up to eight specific
individuals so the camera prioritizes them
when detecting faces. This feature not
only works together with Smile Shutter
and Face Detection, but also supports
Tracking Focus.
Exposure compensation and
bracketing
Getting the exposure just right is
easy with the a77. You can use
Exposure Compensation to increase or
decrease the exposure in 1/3 or 1/2
stop increments between -5 and +5
EV. Or use Auto Exposure Bracketing
(AEB) to automatically record three
or five images at different exposure
values (standard, higher and lower
exposure values), compare the results
and choose the best one. AEB lets you
choose whether to vary the exposure
values by 0.3 or 0.7 EV. Both Exposure
Compensation and AEB clearly display
results on the screen for easy checking
and help ensure that at least one of
your shots is expertly exposed.
AUTO+ (Auto Advanced) mode
This highly convenient mode adjusts
camera settings automatically. So you
can simply point, shoot and let the
camera handle everything else. The
AUTO+ mode automatically analyzes
shooting conditions and intelligently
adjusts everything from aperture and
shutter speed to ISO sensitivity and white
balance on the fly. When you shoot fast
moving subjects, Continuous Advance
Priority AE automatically activates to keep
pace. When scenes are high in contrast
but lack detail in shadows or highlights,
Auto HDR automatically kicks in to bring
out more of the details. Activated settings
and features are also displayed on
screen so you can see what features are
best suited to each
kind of scene. With
the a77, it’s easy to
take advantage of
leading-edge Sony
digital technology.
Two-axis White Balance
In addition to automatic white balance
and a full range of white balance
presets, the a77 provides a two-axis
White Balance mode for even finer white
balance adjustment. This mode lets you
adjust white balance in the amber-blue
and green-magenta directions to achieve
more true-to-life color under almost any
kind of light source.
