DSLR-A850

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.

3.0” Xtra Fine™  LCD (921K pixels) 

Review your images in stunning detail 
on the 3.0” Xtra Fine™  LCD display 
(921k pixels). With photo-quality 

resolution of 270ppi (pixels per inch), 
you can identify any necessary focus or 

exposure corrections at the time of 
capture, rather than discovering them 

when you transfer your images to your 
PC.

PhotoTV HD viewing w/ HDMI™  output 

The 

α

850 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).

40-Segment Multi-Pattern Metering

A 40-segment multi-pattern metering 

system provides superior exposure 

control accuracy in a wide range of 
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.

On-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 

α

850 

features a highly accurate F2.8 sensor 
for improved focus precision when 
using lenses faster than F2.8.

Updated Image Data Converter SR3

Updated Image Data Converter SR3 
software improves your workflow with 
faster RAW file processing and 
improved image correction.
