Sony Alpha SLT-A77 system camera : Sony extends the appeal of its Translucent Mirror camera range with a new A-mount camera model appealing to advanced amateur photographers and serious photo enthusiasts. Latest refinements in Translucent Mirror Technology by Sony make the Sony SLT-A77 the quickest, most responsive interchangeable lens camera in its class. Revised ergonomics on the Sony A77 include a comfortably contoured new grip design and tactile new button layout for ‘eyes off’ operation while viewing via the high-resolution XGA OLED Tru-Finder. A long-awaited successor to the acclaimed A700 DSLR, the Sony A77 adds further refinements in performance and ruggedized construction to handle gruelling photo assignments with ease.
Sony A77 camera body
A natural successor to the enthusiast-oriented A700 DSLR, the Sony A77 adds double control dials for intuitive fingertip operation and a separate top-mounted LCD data display. The durable Sony A77 body features magnesium alloy panels for strength and lightness. Key controls are sealed against the effects of dust and moisture, complementing similar levels of protection offered by the new Sony SAL1650 lens, VG-C77AM Vertical Grip and HVL-F43AM flash unit. Underlining the camera’s rugged credentials, a new shutter unit is tested to 150,000 cycles and supports an ultra-fast minimum 1/8000 sec shutter speed (1/250 sec flash sync). On-board GPS allows automatic geotagging of photos and video clips with location data.
Sony Alpha 77 system camera
The new Sony Alpha 77 system camera boasts the world’s fastest continuous AF shooting performance, capturing a burst of full-resolution images at 12 frames per second with full-time phase-detection autofocus. Precision AF tracking of moving subjects is crisper and more responsive than ever, thanks to a newly-developed 19-point autofocus system with 11 cross sensors. Tracking Focus on the Sony A77 maintains accurate focus lock on a designated moving subject, even if the target’s momentarily obscured by the motion of another object. Razor-sharp responses are reinforced further by a new electronic front shutter curtain that achieves a pro-class minimum release time lag of approx. 0.050 seconds.
Image quality of the Sony A77
The Sony A77 features a newly-developed Exmor APS HD CMOS sensor with 24.3 megapixel resolution. The sensor of the Sony A77 is teamed with the latest revision of Sony’s BIONZ image processing engine that handles huge amounts of high speed data from the camera sensor. This unique combination of sensor and BIONZ processor delivers unprecedented shooting responses, plus flawless image quality with ultra-low noise when shooting still images or Full HD video. A broad sensitivity range of ISO 100-16000 is expandable down to ISO 50. At highest sensitivity, the Sony Alpha 77 can freeze rapid sporting action with very quick shutter speeds, or capture atmospheric low-noise shots without flash. Low ISO settings are ideal when teamed with a long exposure for creating expressive shots of moving water.
Sony Alpha 77 LCD display
Still photos and video can be composed and reviewed on the adjustable-angle 7.5 cm (3.0") Xtra Fine LCD that offers high resolution (921k dot) and TruBlack technology for superb detail and contrast. As an extra refinement, the Sony A77 introduces the world’s first 3-way adjustable screen that tilts and pivots freely for effortless framing at any angle.
Sony A77 electronic viewfinder
The Sony Alpha 77 showcases the world’s first XGA OLED Tru-Finder. With an unprecedented 2359k dot (XGA) resolution, this precision electronic viewfinder offers a bright, detail-packed, high contrast image with 100% frame coverage that is 10 times higher than conventional electronic viewfinders and provides a wide field of view to rival pro-grade optical viewfinders. Detailed shooting information is displayed with a choice of five display modes. The effects of adjusting exposure, white balance and other settings are previewed in the Tru-Finder in real time. Fine focus tweaks can also be confirmed via a zoomed-in portion of the image.
Sony A77 video recording in Full HD
The Sony Alpha 77 brings further refinements to the acclaimed Quick AF Full HD Video shooting as already featured on previous Translucent Mirror Technology from Sony. Phase Detection maintains accurate focus during video shooting of portrait subjects, even when they’re moving. In another, first for consumer-oriented APS-C cameras, Full HD video is now supported at 50p (progressive) frame rates, reflecting recent enhancements to the AVCHD (Ver. 2.0) format. 25p shooting is also available for beautifully ‘filmic’ video footage. Creative video options are extended further by the addition of manual focusing and P/A/S/M exposure modes familiar to still photographers.
Sony DT 16-50mm F2.8 SSM zoom lens
The growing range of compatible A-mount lenses for the Sony A77 now includes the quiet, bright Sony DT 16-50mm F2.8 SSM standard zoom with 16mm wide angle coverage that’s ideal for portrait and everyday shooting. The high performance lens of the Sony A77 features a dust- and moisture-resistant design, and offers a zoom range of approximately 3x range at constant maximum aperture F2.8. Optical performance is assured by two aspherical elements and three ED glass elements to minimize aberration at all focal lengths. An internal SSM (Super Sonic wave Motor) drive assures fast, quiet autofocus.
Sony A77 - VG-C77AM Vertical Grip
Available as an option, the dust- and moisture-resistant Sony VG-C77AM Vertical Grip assures comfortable handling in vertical shooting positions. It can house up to two NP-FM500H InfoLITHIUM batteries, doubling shooting stamina to approx. 1060 shots (via LCD monitor)/940 shots (via Tru-Finder) when using Memory Stick PRO Duo media.
Sony A77 - HVL-F43AM external flash
The compact yet versatile Sony HVL-F43AM external flash is optimised for superb results with all A-mount cameras with a powerful output of GN43, Quick Shift Bounce adjustment, wireless ratio control and dust/moisture resistant design. This is complemented by other new A-mount system accessories that include a back pack, soft carrying cases, LCD protectors and eyepiece cups.
