On August 24 2011, Sony announced the α77 and α65 cameras
featuring a newly developed Exmor APS HD CMOS sensor with 24.3 Megapixels, as well as the world's first XGA OLED Tru-Finder viewfinder. These cameras come with Translucent Mirror Technology which make them the fastest, most responsive interchangeable lens cameras in their class. The α77 features a 19-points AF system, enthusiast form factor with ample controls and customization, large 3.0-inch 921K flip and rotate LCD, 12 fps burst rate, and a cutting edge OLED EVF with 2,359,296 dots of resolution, magnification of approximately 1.09x, and 100% frame coverage. It also comes with built-in GPS, 1080P (60fps and 24fps) HD video, and the weather sealed exterior.
The α65 features nearly all of the features from α77, including the sensor, the HD video, the LCD (minus the rotation), the GPS, the EVF, but without weather sealing, controls is simplified, body is smaller, and has a slower max shutter speed (1/4000 vs 1/8000). The burst rate is also lowered from 12 fps down to 10 fps. Sony also announces the new DT 16-50mm F2.8 SSM standard zoom with 16mm wide angle coverage that's ideal for both portrait and everyday shooting. The lens features a dust- and moisture-resistant design, and offers a zoom range of approximately 3x range at constant wide F2.8 aperture. It comes with aspherical glass and three ED (Extra Low Dispersion) lens elements to minimize aberration at all focal lengths, as well as an internal Super Sonic wave Motor (SSM) drive enables fast, quiet autofocus. There is also an optional dust- and moisture-resistant VG-C77AM Vertical Grip for α77, housing up to two NP-FM500H InfoLITHIUM batteries. The α77 will be available in a kit with the new SAL1650 f2.8 lens for about $2000, and offered as body-only for about $1400. The SAL1650 lens will also be sold separately for about $700. The α65 will be available in a kit with a standard 18-55mm lens (SAL1855) for about $1000, and offered as body-only for about $900. Here's the summary of review of the Alpha SLT-A77 by ePhotoZine, giving the camera a rating of 4.5 out of 5:
"There is some barrel distortion at the wide end which can be fixed by switching on distortion correction in the camera. There is very little pincushion distortion at the telephoto end meaning that switching on distortion correction made very little difference to the image. Purple fringing and chromatic aberrations can be seen in the photo of the trees. The lens appears to be very resistant to flare helping keep images contrasty and sharp. ISO Noise Performance: The A77 allows the ISO to be set from ISO50 which gives slightly lower noise at than ISO100. Noise is low at ISO100 to ISO400 with colour, detail and noise control appearing very good. At ISO800 noise becomes more noticeable as it starts to creep into images. At ISO1600 chroma noise starts to become more visible. At ISO3200 / ISO6400 noise continues to increase with ISO3200 producing usable results. It's at ISO6400 and above that you will need to pay closer attention to noise and whether further processing will be required as detail is lost, particularly in darker areas.
The Sony Alpha A77 is an enjoyable camera to use that is capable of producing some excellent photos, with great colour, detail and extremely solid exposure performance. Reds are extremely vibrant and colourful and the camera produces excellent JPEG output straight from the camera, even on default settings. Noise control is very good with low noise right up to high ISO settings. The cameras also offer continuous focus when using the video mode. The camera is also extremely quick in use, with the camera simply not getting in the way of you achieving the shot. The A77 body only is £1099, this puts it in direct competition with the 18 megapixel Canon EOS 7D. The A65 body only is £699 making the A77 £400 more expensive than the A65. Both cameras have high speed shooting and focusing with a 24.3 megapixel sensor. They both feature a new OLED EVF that is excellent - although in extremely contrasty situations an optical viewfinder may be preferred. Looking at the recently introduced competition there are a few things missing from the A77 that you would see on a higher end camera, such as dual card slots, ethernet socket and Wi-Fi support, although this can be solved by using an Eye-Fi card and other cameras with these features tend to cost double the price (at least). However, considering the price and bucket full of other features such as GPS and high speed specifications built in to the camera, the Sony Alpha A77 represents excellent value for money."

"The most unusual capability of the Sony A77's video mode is enabled by its translucent mirror. The Sony A77 can continue to use phase detection autofocusing during movie recording, allowing swift adjustments to focus as your subject moves. Since standard Alpha-mount lenses are used, this focusing action is accompanied by significant levels of autofocus driv..." More »

"Coming from a Nikon DSLR background, I did not know what to expect from the newly released Sony SLT-A77 camera. Its impressive performance characteristics, high resolution and bundled features were the reason why I decided to give Sony a try. After several months of using the camera in various environments, I am happy to say that I am very impressed by this..." More »

"The new Sony SLT (single-lens translucent) cameras use a fixed translucent or "pellicle" mirror that lets most of the light coming through the lens go straight to the sensor, while also continuously bouncing a little of the light up to an ultrafast phase-detect autofocus sensor. The SLT design does mean a little less light reaches the imaging sens..." More »

"The SLT-A77 builds on the foundations laid by the SLT-A33 and A55. If there were any doubts that a camera with a fixed semi translucent mirror and continuous live view could outperform traditional SLRs then Sony has laid them to rest with the A65 and A77. Some features are pivotal, not least of which is the ultra-high reolution OLED EVF. Sure footed and ver..." More »
