Sony also gave the A77 their 2nd generation Translucent Mirror Technology system. It allows the camera to focus with the speed and accuracy of Phase Detection AF and shoot simultaneously. The camera also boasts Sony's upgraded BIONZ image processor. The processor performs many functions, including efficiently transferring shot data to the chip in your memory card. It also reduces visual noise, and ensures that functions such as 6-image layering and 2D/3D Sweep Panorama work smoothly, and with the necessary speed.
More than a still camera, the SLT-A77 also captures high-quality 1920 x 1080p AVCHD video at 60p or 24p. HD movies can also be captured with full manual control. That means the entire mode dial is at your disposal: Program, Shutter Priority, Aperture Priority, and Manual. Live View, Full-Time Live View (in LCD or EVF) are also available for use as is Full-Time Phase Detection AF. What the DSLR also offers, above and beyond most less-sophisticated cameras, is a viewfinder, the way all your heroes used to shoot. The A77's OLED viewfinder gets your eye off the LCD screen and into the right situation for capturing successful images. Like all viewfinders, this one keeps distractions and glare at bay. But what the OLED viewfinder does that's above and beyond the pack includes a reduction of motion blur on the Tru-Finder screen. The OLED features 2359K dots of resolution and a high contrast ratio. It also allows you to see the results of camera adjustments in real time with true-to-life color and detail.
This one tilts and swivels for everything from hard-to-get shots to successful reviewing of footage in harsh lighting conditions. How about self-portraits? When it's not in use, the screen folds flat to the camera for safe storage and traveling.
First, the camera supports burst shooting up to 12 frames per second at full resolution; that's great news for sports photographers. Then there's the 16,000 ISO sensitivity and the 1200-zone exposure metering. The metering function reads directly from the camera's main image sensor and offers the choice of Multi, Center, and Spot metering.
As for more proprietary shooting features, the camera has a load of those too! Getting into the menu functions you'll find options such as 19-point Auto Focus, Object Tracking AF, and 6-image layering just to start. Dig a little deeper and Handheld Twilight mode and Multi-Frame NR are there to help you capture excellent low-light images.
You'll also find extras such as built-in GPS. The integrated GPS receiver records the location and time of every shot you take, allowing you to view them later on a map with compatible computer and Internet applications. This feature is also great for those into 'geo-tagging'. Eleven Picture Effects modes also give you another way to express yourself with options like Pop Color, Retro Photo, Toy Camera, and more. Old standards like face detection and Sony's Smile Shutter technology are there for your use as well.
Like any good DSLR worth its salt, Sony gave the SLT-A77 a built-in flash for capturing low-light shots with ease. That same flash can also trigger an optional wireless flash. The camera also has an integrated hot shoe for attaching various external flashes and flash accessories (sold separately).
2nd Generation Translucent Mirror Design
Other DSLRs can shoot. Or they can focus with the speed and precision of Phase Detection AF. They cannot do both at once. Sony changes all that with the award-winning Translucent Mirror Technology system. It directs light to both the image sensor and the Phase Detection AF sensor simultaneously 24.3Mp Resolution
You get incredible detail and gorgeous enlargements thanks to an APS-C sensor with 24.3 megapixels
Up to 12 Frames Per Second Continuous
The translucent mirror makes it far easier to capture the decisive soccer kick or your baby at her absolute cutest. Shoots up to 12 frames per second at full-resolution 24.3 megapixels with continuous auto focus (AE locked after first frame). This is the world's fastest shooting speed for interchangeable lens APS-C cameras, as of August, 2011
OLED Viewfinder
There's never been anything quite like the Tru-Finder OLED electronic viewfinder. For size, speed and brightness even after sunset, this is a gem. It begins with 2359K dots for amazing resolution and high contrast ratio for incredible depth. OLED reduces motion blur to a bare minimum. You can also see the results of camera adjustments in real time with superb color and detail
HD Movies at 60p, 60i, or 24p
Capture spectacular HD Movies. This is the world's first DSLR to offer a choice of super-smooth 60p, standard 60i or cinematic 24p, all at Full HD 1920 x 1080 resolution. AVCHD Progressive codec delivers stunning picture quality. MP4 codec offers smaller files for easier upload to the web
HD Movies with Full Manual Control
Now you don't need to surrender control when you shoot HD movies. Enjoy the full expressive potential of Program, Shutter Priority, Aperture Priority or Manual (P/A/S/M) control in HD movie mode
Full-Time Phase Detection AF
You get fast, accurate auto focus in every mode-even HD Movie and Live View-thanks to Sony's exclusive Translucent Mirror Technology. While Contrast Detection Auto Focus often hunts for correct focus, Phase Detection AF knows exactly where correct focus is, and goes straight for it
Full-Time Live View in LCD or EVF
You can use both the LCD monitor and OLED Electronic Viewfinder for composing shots in Live View. Both provide a what-you-see-is-what-you-get preview of white balance, focus, depth of field, exposure and 100% framing accuracy, plus informative on-screen displays
Short Release Time Lag
Helps ensure that the image you want is the image you get. Once auto focus occurs, release time lag is the delay between fully pressing the shutter release and when the camera actually starts taking the picture. Long lag makes it harder to capture fast-moving objects. The Sony A65 boasts a short DSLR release time lag at only 0.05 seconds
Rugged, Magnesium Alloy Body
The SLT-A77 is built for the real world with a magnesium alloy body that combines high strength with light weight. Ports, doors and controls are also weather-resistant for smooth operation under adverse conditions
Object Tracking AF
