Dramatically improved BIONZ
®
image processing engine
Sony’s lightning-fast BIONZ processor
employs powerful algorithms to generate
beautiful images from RAW data
captured by the Exmor CMOS image
sensor. Fully optimized to match the
characteristics of the sensor, it delivers
extremely accurate color and rich
tonal gradations throughout the entire
dynamic range. Even during ultra-high-
speed continuous shooting and Full HD movie shooting, it effortlessly handles
the vast information generated by the
24.3 megapixel CMOS sensor as well as
other intensive tasks such as advanced
digital compositing. Moreover, RAW image
noise reduction complements dual noise
reduction in the sensor to deliver images
of superb quality with extremely low noise.
New 24.3 megapixel Exmor™ APS HD CMOS sensor
Stunning images brimming with detail are
yours at an astounding 24.3 megapixel
resolution, thanks to Sony’s new proprietary
Exmor APS HD CMOS sensor. This ultra-
high resolution is complemented by an
extra-large sensor size that raises sensitivity
in low-light conditions and strengthens
background defocusing effects. So you can add depth and drama to virtually
any scene. Dual noise reduction also
significantly reduces noise during analog
and digital signal conversion to ensure
smooth, crystal-clear reproduction even in
low-light conditions.
ISO 6400 ISO 1600 ISO 12800
Breathtaking image quality in any lighting
* SAL1650, SAL1855, SAL55200-2 and SAL18250.
Firmware updates are planned to expand the
number of supported lenses.
70-400mm F4-5.6 G SSM (SAL70400G), 1/15 sec., F5.6, ISO 200, Manual white balance (3700K)
High sensitivity with ISO 100–16000
(expandable to ISO 50)
Master virtually any lighting conditions with
extremely high ISO sensitivity and wide-
ranging settings from 50 (expanded) to
16000—a range of eight 1/3 steps. Capture
the mood of a candlelit wedding ceremony
with a high sensitivity setting; the flow of
a river with a low sensitivity setting and
slow shutter speed; or athletes competing
indoors with a high sensitivity setting and
high shutter speed—all with extremely high quality and low noise courtesy of Sony’s
ultra-sensitive Exmor APS HD CMOS sensor
and advanced BIONZ image processor.
In regular shooting conditions, you can
take full advantage of an Auto ISO mode
that automatically chooses the optimal
ISO setting between ISO 100 and 1600 or
between any available range you choose
to customize (from 100 to 12800) for
creative results.
SteadyShot INSIDE™
image stabilization
Advanced image stabilization lets you
enjoy handheld shooting with minimal
camera-shake blur. Since SteadyShot
INSIDE utilizes a sensor-shift image stabilizer
within the camera itself. It provides effective
image stabilization for any A-mount system
lens from wide-angle to telephoto. It also
lets you capture sharp images at shutter
speeds up to 2.5 to 4.5 steps slower than
otherwise possible without a tripod or
flash, as well as take advantage of vastly
increased photo opportunities.
New lens shading and aberration
compensation
To ensure optimal shooting results,
the
a
77 automatically compensates for
the shading and aberration characteristics
of the particular lens you mount. This
includes vignetting (peripheral shading),
lateral chromatic aberration and optical
distortion, which can each be manually
activated or deactivated as desired.
Embedded data within the camera on
supported A-mount lenses* ensures
optimal compensation every time.
