• A newly developed 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 α900. This wide and high ISO sensitivity combines with extremely low noise to make the α99 a brilliant performer in dim lighting.

• Highly advanced BIONZ image processing engine
  With the help of a newly developed high-speed front-end LSI, the BIONZ imaging engine processes the massive volume of image signals from the full-frame Exmor CMOS Sensor at an extremely high speed while realizing 14-bit RAW output, rich gradation and low noise, thanks in part to a new area-specific noise reduction (NR) system powered by a newly developed algorithm. These core features also realize high sensitivity and a wide sensitivity range of ISO 50* to 25600 that covers a maximum range of 9 stops.

  * An expanded sensitivity setting.

• Dual AF System (19 + 102 points)
  Dual AF System is the world’s first* AF system to employ two phase detection sensors. By maximizing the strengths of both sensors, it vastly improves subject tracking performance as well as focusing precision. The 19-point (11 cross-point) phase detection AF sensor mounted above the translucent mirror provides high-precision focusing performance and depth detection, while the 102-point focal plane phase detection AF sensor overlaying the image sensor offers the advantages of wider depth and width (object plane) coverage. Together, these sensors deliver a new level of AF performance and functionality.

  * The world’s first AF system in a 35mm full-frame interchangeable lens digital camera to feature two phase detection sensors as of September 12th, 2012, according to Sony’s internal survey..
