Accelerated response on a full-time basis Translucent Mirror Technology Sony Translucent Mirror Technology revolutionizes interchangeable-lens photography by enabling simultaneous focusing and image capturing on a full-time basis. Unlike competing cameras that swing a mirror to either direct light toward the AF sensor or the image sensor-one at a time, the a77 continuously directs light to both sensors simultaneously via a stationary translucent mirror.This breakthrough enables leading continuous shooting speed, accelerated full-time continuous phase-detection autofocusing- even while shooting HD movies-and smooth uninterrupted live-viewing on the finder and rear monitor during single shot, continuous and movie shooting. Quite simply, Translucent Mirror Technology significantly improves overall performance and leaves the competition behind. Cross sensors AF sensors Full-time Continuous AF Accelerated full-time continuous phasedetection autofocusing keeps your subject sharply focused at all times. Even at maximum continuous shooting speed and during live-view movie shooting-thanks to revolutionary Translucent Mirror Technology- you can clearly capture sports action and fleeting facial expressions without resorting to manual focusing. The supreme speed and precision of phase-detection autofocusing is faster and more precise than the contrast-detection AF systems employed by competing cameras. It lets you effortlessly capture dramatic moments in all types of situations with professional-looking results. 12 fps continuous shooting (in Continuous Advance Priority AE mode) The world's highest continuous shooting speed* gives you a decisive advantage when capturing sports action and fleeting facial expressions. Every second, you can capture up to 12 images with clarity and precision at full 24.3 megapixel resolution. Moreover, you can enjoy the expressive power and flexibility of interchangeable lenses without slowing down performance. As with full-time autofocusing, this extraordinary response is made possible by innovative Sony Translucent Mirror Technology. * Among interchangeable-lens cameras with an APS-C sensor as of August 2011. Notes: Continuous shooting speed may be slower depending on shooting conditions. In Continuous Priority AE Mode, the aperture is fixed at F3.5 or the maximum aperture of the lens, whichever is smaller. Continuous shooting speed (fps) lowers when high ISO NR function is On. Approximately 0.05 second minimum release time lag Accelerated shutter response lets you capture decisive moments with confidence. An innovative electronic front curtain shutter in the image sensor slashes shutter release time lag to a class-leading 0.05 second* and produces less shutter noise and vibration than a mechanical front curtain shutter. If desired, a mechanical front curtain shutter can be activated through the MENU. * Speed may vary depending on shooting conditions and memory card in use. 10 70-400mm F4-5.6 G SSM (SAL70400G), Continuous Advance Priority AE, 1/4000 sec., F5.6, ISO 1250, Auto white balance 19-point AF system with 11 cross sensors The new phase-detection autofocusing system spreads 19 AF sensors over a wide AF area to increase your framing freedom and keep moving subjects in focus. It includes 11 cross sensors that deliver more accurate and reliable tracking than sensors with only vertical or horizontal detection can achieve. Additionally, this new AF system improves autofocusing performance in low light conditions to ensure precision focusing wherever and whenever you shoot. Depending on your needs, you can select one of four AF area modes: Wide (all 19 sensors), Spot (central sensor), Local (any selected sensor), or Zone (right, center, or left zone). Four AF modes are also selectable from the focus mode dial: AF-A (Auto), AF-C (Continuous), AF-S (Single shot) and Manual. In addition to AF (Auto Focus), the camera also provides DMF (Direct Manual Focus) and Manual focus modes. Object Tracking Focus Various advances come together in the a77 to enable swift, accurate tracking of fast-moving subjects. Once you designate your subject on the viewfinder or rear LCD, Tracking Focus utilizes powerful predictive focusing algorithms and Sony's original subject recognition technologies to track your subject's every move with speed and precision.This performance is supported by blazing-fast BIONZ® image processing and 19 autofocusing points that are spread over a wide area to better keep moving subjects in focus. Easy operation even during manual focusing The camera quickly and comfortably meets your needs during both auto and manual focusing. Prompt switching between autofocusing and manual focusing is as simple as pressing the AF/MF button. Manual focusing is aided by a Focus Magnifier function that provides up to 11.7x magnification of the image at the press of a button, and Direct Manual Focus (DMF) settings are selectable during autofocusing. An AF Micro Adjustment function also allows minute manual adjustment of focusing distance, along with registration of up to 30 sets of lens adjustment settings. 11
