Digital Single Lens Reflex Camera
The rugged Sony®
α
850 DSLR features a 35mm full frame 24.6 megapixel Exmor™
CMOS image sensor and SteadyShot INSIDE™ body-integrated image stabilization
for a full frame DSLR. In addition, Dual BIONZ™ imaging processors allow
continuous shooting up to 3 fps with superb image quality and ultra-low noise.
35mm full frame 24.6MP Exmor™
CMOS image sensor
The A850 features a 35mm full frame
Exmor™ CMOS image sensor that is
approximately 2.35x larger than the
APS-C sized sensors found in many DSLR
cameras. The result is a larger capture
area, improved wide angle
performance, and tighter depth of field
control. In addition, its 24.6MP
resolution maximizes the resolving
power of your existing lenses and
delivers sharper, higher contrast photos.
SteadyShot INSIDE™
in
-camera image
stabilization:
Building on years of expertise, Sony has
developed the world’s first body-
integrated image stabilization solution
for a full frame DSLR . The SteadyShot
INSIDE™ in-camera image stabilizer
actually shifts the image sensor to
compensate for camera shake without
sacrificing image quality. The
compensation effect is equal to as
many as four shutter speed steps, giving
you more creative freedom when
shooting in low light. And, because it is
integrated into the camera body,
SteadyShot INSIDE technology works
with all compatible α
system lenses.
Dual BIONZ
™
processors for up to fast
3fps performance:
The
α
harnesses the power of Dual
BIONZ™ image processing engines to
deliver true
-to-life images with ultra-low
noise and continuous shooting at up to
3 fps.
Ultra bright, 98% coverage glass
pentaprism viewfinder
A large, ultra bright glass pentaprism
viewfinder provides you with amazing
clarity and high optical performance
for tighter focus control. In addition, it
offers viewfinder magnification of 0.74x,
allowing you to see an image nearer to
its actual size, as well as 98% field
coverage for detailed framing work.
Intelligent Preview Function
The Intelligent Preview function allows
you to see the effects of manual
adjustments to exposure value, shutter
speed, aperture, Dynamic Range
Optimizer and White Balance before
you take the shot, so you can determine
the optimum settings before you take
the shot, instead of losing time to trial-
and-
error.

The
α850 provides direct HDMI™
output
to your BRAVIA® HDTV and other
compatible HDTV screens, so you can
view and share photos in breathtaking
clarity and detail Additionally, PhotoTV
HD capable BRAVIA HDTVs will
automatically optimize display
settings, such as sharpness, gradation,
and color to display your images in a
way that more closely matches the
natural look of printed photographs
Precise and fast 9
-point AF system w/ 10
point assist
A high-performance autofocus system
uses 9 focus points (center dual
-
cross
type) and 10 assist points to deliver fast
and precise focusing.
Rugged magnesium alloy shell
The body of the A900 is entirely covered
in a die-cast magnesium alloy shell,
providing a rugged feel and
surprisingly lightweight.
Moisture/dust
-
resistant design
Sealed viewfinder optics and rubber
gasket surrounds on all buttons, dials,
and switches help resist the entry of dust
and moisture into the camera, and
allow for safe use in a wide range of
environments.
Anti
-
Dust Technology
Changing lenses in a DSLR can allow
dust to enter the camera
-- so to help
keep the CMOS imager cleaner for
better pictures, the Sony
® α
; (
alpha)
DSLR-A900 utilizes both static-
free anti
-
dust coating on the imager's filter and
anti-dust vibration that automatically
shakes the sensor to dislodge dust each
time the camera is shut off.
Battery Performance
A supplied InfoLITHIUM® lithium-ion
battery provides long-lasting
performance, allowing you to capture
approximately 880 images on a single
charge
.
Durable Shutter Design
The shutter mechanism in the A900 is
designed to achieve shutter speeds up
to 1/8000 seconds and proven for
100,000 cycle operation.
Dual Card Slots
The A900 features a dual card slots and
accepts both CompactFlash® and
Memory Stick Duo™ Media (sold
separately).

lighting conditions.
Dynamic Range Optimizer
To recover details in dark or bright
areas of the image, the A900 provides
multiple levels of Dynamic Range
Optimization: Standard mode, to
improve shadow detail using standard
gamma curves; Advanced Auto mode,
allowing you to select any of 5 DRO
correction levels, or DRO Advanced
Bracketing, which automatically takes
three shots at different DRO levels with a
single shutter press.

-Chip Column A/D Conversion
Analog-to-digital signal conversion is
performed by the full frame Exmor™
CMOS image sensor.
Dual Noise Reduction Processing
In addition to digitizing analog
signals, the full frame Exmor™ CMOS
image sensor also performs both
analog and digital noise reduction.
This on-chip dual noise reduction
process aids in the high speed transfer
of noiseless digital signals.
F2.8 Sensor
The autofocus system in the
α850
features a highly accurate F2.8 sensor
for improved focus precision when
using lenses faster than F2.8.
