24.3 megapixel 35mm full-frame Exmor CMOS sensor
The new 24.3 megapixel 35mm full-frame Exmor CMOS sensor delivers
beautiful, finely detailed images from corner to corner with a wide
dynamic range and low noise. Thanks to innovations that only Sony—one
of the world’s leading image sensor developers—could achieve, the sensor
is 1.5x more sensitive and 2x more effective at eliminating random noise
than the acclaimed
a
900. This wide and high ISO sensitivity combines with
extremely low noise to make the
a
99 a brilliant performer in dim lighting.
Photographers and cinematographers will also welcome the gorgeous
bokeh and full compatibility with full-frame wide-angle lenses.
Light concentration technology
Sony compressed the height of circuitry within the image sensor via newly developed
proprietary processing technology to dramatically increase the amount of light
collected by each pixel. This vastly improved light-gathering efficiency results in
significantly higher sensor sensitivity, much lower noise, an impressive signal-to-noise
ratio and outstanding image quality in virtually all shooting conditions.

technology
By taking full advantage of optimized
image sensor circuitry, Sony significantly
increased the size of the photo diode
at every pixel. These larger photo diode
dimensions more than doubled the
sensor’s dynamic range in comparison
with the
a
900—a major breakthrough
in performance that delivers smoother,
richer image gradation. The larger
dimensions also improved the signal-
to-noise ratio by further increasing
sensitivity and lowering noise.
