B&H Photo Video is pleased to share with the Photography community the launch of the Sony SLT-A99 Full-Frame DSLR camera, designed to meet the needs of ardent photographers who demand outstanding performance and reliability, and unparalleled levels of control, speed, and accuracy.

The SLT-A99 Digital Camera from Sony is a 35mm full frame digital camera body equipped with Sony's translucent mirror technology. This enables it to shoot without the delay of a reflex mirror, and its Dual Autofocus System to continuously monitor and alter its focus in real time. Recording on a 24.3MP resolution Exmore CMOS sensor, the A99 has great image quality and low-light sensitivity, while using the speed of the translucent mirror and BIONZ Image Processor to record images at 6fps in continuous shooting mode.

This sensor allows for an ISO range of 100 to 25600 while area-specific noise reduction allows one to shoot at the higher end of that sensitivity range.

Utilizing Sony's Translucent Mirror technology, the autofocus system continuously monitors the image and can alter the autofocus in real time. Two phase contrast sensors, a 19-point sensor above the translucent mirror and a 102-point focal plane phase detection sensor, work in tandem to greatly improve subject tracking performance and increase autofocus precision.

For increased clarity and resistance to reflections, the rear 3.0" LCD features Sony's TruBlack technology. It has a 1,228k dot resolution for sharp, vivid imagery when reviewing images, or when framing them using Live View. It is also able to tilt up to 180° vertically and can rotate up to 270° horizontally.

The large 14-bit data generated by the full-frame sensor is easily handled by the enhanced BIONZ image processor, to deliver fast speeds and performance. This provides significantly reduced write times, while the increased power afforded by the processor allows for increased noise reduction throughout the entire dynamic range of the sensor.

Using sensor-shift image stabilization, Sony's SteadyShot technology takes place inside the camera rather than in the lenses. This means that every image captured, no matter the lens that was used, has image stabilization applied. By reducing camera shake within the camera one can achieve shake reduction of up to 2.5 to 4.5 stops, so the shutter speed will not need to be set as low as it would without the stabilization.

Depending on the Sony lenses, the camera will also detect and compensate for its particular aberrations and degradations in image quality. Shading or vignetting caused by the lens will be corrected, and aberrations like lens distortion or chromatic aberration will be compensated for.

The noise reduction system used by the Sony A99 applies optimized settings to specific parts of the images based on patterns including edges, textures and gradients. It processes these areas using the best and most appropriate settings to optimize image quality, and reduce noise. This is all in addition to the conventional noise reduction techniques employed by the camera, and helps to produce images with low noise throughout its wide ISO range.

The unique Multi Control Dial on the front of the camera allows one to adjust photo, video or audio settings without producing audible clicks or vibrations that may be heard while recording. Full HD 1080p video is supported with this camera and makes use of the high-speed Translucent Mirror technology for continuous autofocus, even while using Live View to monitor your shooting. The 24p frame rate allows one to create movies with a more cinematic feel, and for even greater control ISO sensitivity, P/A/S/M manual shooting modes.

Dual Autofocus System Utilizing the Translucent Mirror technology, the autofocus system is able to continuously monitor the image frame and alter the autofocus quickly and responsively. Two phase contrast sensors, a 19-point sensor above the translucent mirror and a 102-point focal plane phase detection sensor, work together to deliver greatly improved subject tracking performance and increased precision.

Full HD Video Recording Full HD 1080p recording is supported with this camera and also makes use of the high-speed Translucent Mirror Technology for continuous autofocus, even while using Live View to monitor your shooting. The AVCHD format is used and allows recording of 60 frames per second (60p) for outstanding clarity and motion detail. Additionally, the 24p frame rate is supported allowing one to create movies with a more cinematic feel. For even greater control over video recording, P/A/S/M manual shooting modes, selection of ISO from 100 to 6400.

The enhanced BIONZ image processor easily handles the large 14-bit data generated by the full-frame sensor to deliver fast speeds and performance. It offers significantly reduced write times. The increased power afforded by this processor allows increased noise reduction and richly detailed gradations throughout the entire dynamic range.

Full-frame images can be captured at 6fps with the dual AF system. When using the Tele-zoom High Speed Shooting mode, up to 10fps can be recorded while magnifying the center of your image by 1.46x. This cropping limits your image resolution somewhat and brings your subject closer for tighter compositions.

Two-Axis White Balance Enabling finer white balance adjustment than auto white balance is capable of, you can adjust white balance using amber to blue and green to magenta spectrums in order to achieve more true-to-life color using almost any kind of light source.

Auto Portrait Framing Auto Portrait Framing automatically creates compositions revolving around your portrait subjects and artfully crops your image based on the rule of thirds, where your portrait is located within the frame, exposure on your subject, and the direction he or she is looking. Face Detection, Smile Shutter, and Face Recognition modes are used in conjunction with Auto Portrait Framing for creating the best portraiture possible in a highly efficient manner.
