Sony takes its interchangeable lens offerings in yet another direction with the sony a55. Instead of being mirrorless, the new digital cameras employ a “translucent mirror,” more commonly known as a pellicle mirror. The sony a55 advanced translucent mirror remains fixed in place during operation, allowing most of the light to reach the imaging sensor, while a small percentage is reflected to a dedicated autofocus sensor. It’s what this high technology allows that’s so exciting: real-time, phase-detect autofocus while firing off up to ten 16.2 megapixel images per second in the sony a55.
Another from Sony is the DSLR-A550. This also offers a fast processing for faster response on data-intensive 14.2-megapixel images. Sony Alpha DSLR-A550 has made with more responsive Live View so you will definitely not miss any special moment. This Sony Alpha DSLR-A550 DSLR camera’s Quick Auto Focus Live View helps you solve your problems regarding slow focusing or the blacking out on the LCD before focus. You can also achieve finer and detailed photos through the Manual Focus Check Live View. The temporary 7x and 14x zoom views allow you to focus on very fine detail. On the other hand, the 1x view shows 100 percent framing in the LCD. Sony Alpha DSLR-A550 also features the face detection technology for you to get the appropriate focus, exposure, and white balance. This technology automatically finds the focus on the subject’s face in order to get the center. Sony Alpha DSLR-A550 also ensures that you can capture pictures with all smiles because it has a smile shutter technology that automatically fires the shutter as your subject smiles. Sony Alpha DSLR-A550 has an articulating 3.0 inch LCD monitor with 921k dot composition that helps you capture photos at any angle whether high or low-angle shots. The LCD can be tilted by 90 degrees up or down and features Sony’s Clear Photo LCD display technology. This Sony Alpha DSLR-A550 camera can also be used for capturing in a sports event because it can continuously shoot for up to 7 frames per second in speed priority mode.

Since the translucent mirror of sony a55 only reflects enough light to provide for the autofocus sensor, not an optical viewfinder as most pellicle designs permit, Sony has adopted full-time live view in the sony a55. In place of the optical viewfinder from a traditional SLR, the SLT cameras have an electronic viewfinder with 1,152,000 dot resolution. The sony a55 EVF LCD is time-multiplexed. The sony a55 shows each color in sequence at every pixel location, rather than the separate, adjacent color dots of most electronic viewfinders. This makes it harder to distinguish individual pixels.

Here is a summary of sony a55 review from a satisfied customer:
Handles difficult photo conditions with ease
The a55 makes it easy to shoot great photos in very challenging lighting conditions. The Auto-HDR (digh dynamic range) takes 3 photos and combines them perfectly into one photo, so that very bright sky and darker landscape both are exposed properly in the final photo. The camera also uses a similar process for doing low light situations (where subject movement would cause a blur if no flash was used). These are in-camera processing features that only Sony is offering at this point. The continuous auto-focus during video is also a first for inter-changeable lens cameras. Overall, it’s a great photographic tool.
The sony a55 camera also sport a wide-aspect 3-inch LCD with 921,600-dot resolution. Taking full advantage of the camera’s full-time live view shooting, the super-slim LCD tilts 180 degrees vertically, and swivels 270 degrees for easy viewing from most any angle. The sony a55 also include TruBlack technology borrowed from Sony’s picture frames. Several hot features were brought over from Sony’s NEX and Cyber-shot digital cameras, including Sweep Panorama, 3D Sweep Panorama, Auto High-Dynamic Range, and Handheld Twilight modes, each of which strategically combine and align several images into one seamless shot.

It’s pretty impressive stuff.

This allows both still images and movies to be automatically tagged with information about the location at which they were recorded.
