Sony Alpha SLT-A57 16.1 MP Exmor APS HD CMOS Sensor DSLR Camera With 18-55mm lens
12 fps tele-zoom high-speed shooting
Every second, you can capture up to 12 dynamic close-ups of subjects in motion. Tele-zoom Continuous Advance Priority AE magnifies the center of the action 1.4x to bring subjects closer at a clear 8-megapixel resolution. You can also team Smart Zoom with 2x magnification for super zoomed shots (4MP, S size). The a57 also supports 10 fps continuous shooting at the camera’s highest resolution (16.1 megapixels)4.
The renowned precision of Sony’s 15-point AF system, previously reserved for higher grade models, ensures fast and accurate TTL phasedetection autofocusing wherever and whenever you shoot. Even when capturing moving subjects in dim lighting, the three vertically aligned cross sensors deliver accurate and reliable tracking. You can choose any of four AF area modes (Wide, Zone, Spot or Local) depending on your needs.
High sensitivity (ISO 100-16000)
The large Exmor APS HD CMOS sensor provides an extremely wide sensitivity range of 7 1/3 steps. You can use AUTO ISO (100-3200) for outstanding results in most lighting conditions or manually raise sensitivity up to ISO 16000 when lighting is low. Even at high sensitivity settings, the a57 captures every detail with natural tonal gradations and extremely low noise. This makes the a57 perfect for shooting indoor athletes at high shutter speeds without a tripod or reproducing the mood of candlelit rooms without supplemental lighting.
Full-time Continuous AF
Even at maximum continuous shooting speed and during live-view movie shooting, accelerated full-time continuous phase-detection autofocusing keeps your subject in sharp focus without the slightest delay. This remarkable AF performance, made possible by Translucent Mirror Technology, lets you effortlessly capture dramatic moments and expressions in all types of situations with professional-looking results.
Release time lag
When you press the shutter button, the a57 responds in 0.05 second — a blazing speed that rivals professional cameras. Made possible by an innovative electronic front curtain shutter, this accelerated response lets you capture decisive moments with utmost confidence. The electronic front curtain shutter also produces less shutter noise and vibration than a mechanical front curtain shutter (which can be activated if desired through the MENU).
Enhanced Object Tracking
Newly improved Object Tracking utilizes powerful predictive focusing algorithms, 15 AF points in a wide focus area, blazing-fast BIONZ image processing and Sony’s original subject recognition technologies to track subjects with speed and precision. When your subject is a person, it automatically switches between face detection tracking and object tracking, depending on whether your subject is facing the camera.
AVCHD Ver. 2.0 (Progressive) Full HD 60p (50p)2 movies
Create movies of amazing clarity that play extra smoothly by recording them at Full HD resolution (1920 x 1080 pixels) in the AVCHD Ver. 2.0 (Progressive) format — at the extremely high frame rate of 60 (50)2 fps. You can easily download the movies to your computer for editing and recording to Blu-ray media, which is highly compatible with the AVCHD Ver. 2.0 (Progressive) codec. Sony’s lightning fast Exmor APS HD CMOS sensor and Full-time Continuous AF ensure flawless capture even at accelerated 60 (50)2 fp.
