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.

The

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.
