Images of singular beauty,
from a sensor like no other |
|
Only a company with Sony's long
experience in semiconductor and microprocessor manufacturing could
have developed the α900's remarkable new
24.6-megapixel* 35mm full-frame Exmor CMOS sensor. Designed
specifically to take advantage of the superb resolving power of
high-precision αseries lenses, its high
pixel count and large size assure enhanced image detail and a wider
dynamic range that enables colors and subtle tonal gradations to be
captured just as the human eye perceives them.

24.6-megapixel Exmor™ CMOS
35mm full-frame imaging |
|
The α900's
image sensor is designed from the ground up for 35mm full-frame
imaging, and is produced using proprietary Sony planarization
technologies to ensure an ultra-flat surface across the entire imaging
area. Instead of a single analog/digital converter, the sensor uses
over 6000 on-chip column-parallel analog/digital converters to convert
analog signals to noise-resistant digital signals at the earliest
possible stage. In addition, noise reduction is applied both before
and after analog/digital conversion to ensure cleaner signal output.
The result is not only higher image quality, but also blazingly fast
sensor response.

Dual BIONZ™ image
processing for truly lifelike and natural color |
|
Image processing gets a big boost in
speed and power from new dual BIONZ image processing engines on the
α900. As a result, even the massive amount
of image data captured by the 24.6-megapixel Exmor CMOS sensor can be
processed instantly, assuring you of quick shooting response and truly
natural, what-you-see-is-what-you-get color and tonal gradation. In
addition, the dual BIONZ engines apply advanced noise reduction
algorithms twice — once prior to RAW data conversion and again during
image processing — to ensure an absolute minimum of noise in final
image data.

Faster, more powerful
SteadyShot® INSIDE |
|
To match the larger size and higher
image quality specifications of the new 35mm full-frame Exmor CMOS
sensor, the α900 features a SteadyShot
INSIDE image stabilization system that is 1.5x more powerful, and 1.3x
faster, than previous systems. Enabling you to enjoy handheld shooting
at shutter speeds up to 4 steps slower than would otherwise be
possible,* the body-mounted SteadyShot INSIDE system works with all
compatible α system lenses — including macro and wide-angle lenses —
and doesn't cause the image degradation that can occur with lens-based
optical stabilization systems.

|
* Stabilization effect varies according
to lens and shooting conditions.
