A breakthrough in digital imaging realism
for ultra-fine detail and truly natural color
Images of singular beauty,
from a sensor like no other
Only a company like Sony, with extended
experience in semiconductor and
microprocessor manufacturing, could
have developed the 900’s
remarkable new 24.6-megapixel
1
35mm full-frame Exmor ™ CMOS
sensor. Designed specifically to take
advantage of the superb power of the
high-precision series 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 DSLR A900 camera 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 on the 900 gets
a big boost in speed and power from
new Dual BIONZ image processing
engines. As a result, the 900’s 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 user
selectable 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.

otherwise be possible.

body-mounted SteadyShot INSIDE
system works with all compatible
system lenses — including macro
and wide-angle lenses — and doesn’t
cause the image degradation that
can occur with lens-based optical
stabilization systems.

To match the larger size and higher
image quality specifications of the
)new 35mm full-frame Exmor CMOS
sensor, the 900 features a
SteadyShot INSIDE image stabilization
system that is 1.5x more powerful and
1.3x faster than our previous systems.
