Translucent Mirror Technology
Sony Translucent Mirror Technology revolutionized interchangeable lens cameras by replacing the swinging mirror of SLRs with a stationary translucent mirror that continuously directs light to the AF sensor and image sensor. This innovation enables both full-time phase detection AF and full-time live view through the viewfinder and rear LCD monitor during single shot, continuous and movie shooting.-
Expressive 35mm Full-Frame Moviemaking
Create highly expressive movies with professional-quality bokeh, a stunning sense of depth and extremely low noise even in dark environments. This exceptional performance is made possible by the potent combination of a 35mm full-size sensor, lens interchangeability, ISO 100-6400 sensitivity and various advances from professional Sony movie production equipment.
Capture it all with the 24.3MP effective 35mm full-frame sensor, 14-bit RAW output and a normal sensor range of ISO 100-32000. Add a sophisticated balance of high-resolving power, gradation, and low noise and you're in for a shuttering experience.
Never Stop Shooting
Quickly change settings with just your right hand while still shooting photos. With Quick Navi Pro, you can immediately access all camera parameter settings so you don't miss the action.
Low Light? No Problem.
With sensitivity selectable up to ISO 25600, the a99 handles incredible low-light shooting without a flash (recommended for still subjects). That means it can capture up to six images in a fraction of a second. Combining the data from all six, it creates a single image with a reduction in noise equivalent to two additional steps of ISO sensitivity.
Dual AF for Singular Moments
The world's first Dual Phase Detect AF system perfectly captures decisive moments with precision. The 19-point (11 cross-point) phase detection AF sensor provides high-precision focusing performance and depth detection, while the 102-point focal plane phase detection AF sensor offers the advantages of wider depth and width (object plane) coverage. Together, these sensors deliver a new level of AF performance and functionality.
Keep Your Eye on the Viewfinder
The Tru-Finder™ OLED electronic viewfinder has 2359K dots for amazing resolution and high contrast ratio for incredible depth. OLED reduces motion blur to a bare minimum. You can also see the results of camera adjustments in real time.
Every Lens Tells a Story
Wide angle, zoom, macro and more—having the right lens for the shot is a crucial part of expressing yourself through photography. With a wide variety of available A-mount lenses designed specifically for your a99 DSLR camera, you can choose the perfect piece of glass for every composition and shoot with greater freedom and creative control.

Dual Slot for Freer Control of Data
Experience more freedom to do things your way with dual media slots. One slot supports Memory Sticks and SD memory cards, while the other is fully dedicated to SD cards. This dual slot system allows for simultaneous recording for backup purposes (with recordings sorted RAW/JPEG file type or still/movie data) as well as copying between media. Moreover it allows movie recording to two media cards simultaneously.
The a99 is the world's lightest 35mm full-frame interchangeable lens digital camera. Weighing in at only 740 grams thanks to features like Translucent Mirror Technology and high-rigidity magnesium alloy panels, that translates to agile and flexible shooting despite full-frame specification—all while helping you lighten your load.
Fast Continuous Shooting Speeds
Highly responsive continuous shooting at approximately 6 frames per second (fps) is made possible by Translucent Mirror Technology and an enhanced Tracking Focus function offering more advanced acquisition and tracking performance. You can also raise the continuous shooting speed to approximately 10fps by entering Tele-zoom High Speed Shooting mode.
