The secret to Sony performance

Translucent Mirror Technology simultaneously directs light to the image sensor and AF sensor on a full-time basis to realize full-time live view shooting and accelerated full-time continuous phase-detection autofocusing even during HD

movie shooting. It’s the cornerstone of Sony

interchangeable-lens camera technology.

70-300mm F4.5-5.6 G SSM (SAL70300G), Continuous Advance Priority AE, 1/500 sec., F4.5, ISO 1600

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 57 also supports up to 10 fps continuous shooting at the camera’s highest resolution (16.1 megapixels)*.

* Continuous shooting speed may be slower depending on shooting conditions. In Continuous Priority AE and Tele-zoom Continuous Priority AE modes, the

aper ture is fi xed at F3.5 or the maximum ape rture of the lens, whichever is smaller. Continuous shooting spe ed (fps) lowers when high ISO NR f unction is on.

15-point AF system with 3 cross sensors

The renowned precision of Sony’s

15-point AF system, previously reserved for higher grade models, ensures fast and accurate TTL phase-detection 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.

Three cross sensors contribute to outstanding tracking precision

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 57 captures every detail with natural tonal gradations and extremely low noise. This makes the

57 perfect for shooting indoor athletes at high shutter speeds without a tripod or reproducing the mood of candlelit rooms without supplemental lighting.

Even in dimly lit environments, you can capture moving subjects clearly by using a high-sensitivity setting and fast shutter speed.

Full-time Continuous AF

Even at maximum continuous shooting speed and during live-view movie shooting, accelerated full-time continuous phase-detection auto-focusing 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.

Class-leading release time lag

When you press the shutter button, the 57 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.
