Full-frame DSLR with Translucent Mirror Technology and Dual AF system
The successor to Sony's flagship α900 DSLR, the α99 camera features a brand new 24.3 MP full-frame image sensor, a unique dual phase-detect AF system and a host of other innovative technologies that work together to deliver the best image and full HD video quality in the history of Sony's acclaimed line of α cameras.
"The new α99 camera is the ultimate combination of Sony's expertise and rich history of image sensor production coupled with our truly innovative approach to camera design" said Mike Kahn, director of the alpha interchangeable lens camera division at Sony. "It redefines what can be accomplished with a full frame DSLR camera."
New Levels of Imaging Performance and Response
The flagship α99 model combines its new 24.3 effective megapixel Exmor® CMOS sensor with a highly advanced BIONZ image processing engine, delivering unprecedented levels of performance in both still and video shooting.
The full frame sensor is enhanced by a newly-developed separate multi-segment optional low-pass filter, increasing its resolving power. Assisted by an all-new front-end LSI, the BIONZ engine can process massive amounts of image signal data from the sensor at very high speeds. Together with a powerful new area-specific noise reduction (NR) algorithm, it allows to the camera to achieve 14-bit RAW output, rich gradation and low noise.
The evolved BIONZ processor also gives the α99 model a maximum sensitivity range (in expanded sensitivity mode) as wide as ISO50 – 25600 – a range of nine stops. Its unprecedented processing power enables the camera to shoot a burst of images at up to six frames per second at full resolution or up to 10 fps in Tele-zoom high speed shooting mode.
The new α99 digital camera features a unique dual AF system, a world's first for digital cameras. This camera's main focusing system – a 19-point AF system with 11 cross sensors - is complemented by a 102-point focal plane phase-detection AF sensor overlaying the main image sensor. Harnessing the power of Translucent Mirror Technology, light is passed to both phase-detection AF sensors simultaneously and continually, measuring subject distance and position more completely than other cameras. This unique Dual AF System permits ultra-fast, accurate autofocusing that maintains tracking focus even if a subject temporarily leaves the frame.
