The Sony Alpha SLT-A55 (sibling to the Sony Alpha SLT-A33) is not technically a DSLR camera, however, its Single Lens Translucent (SLT) technology puts it into the same class of cameras. It has a full-time fast phase-detection AF which works in still image mode and movie shooting mode. It is built around a 16.2MP sensor that supports full HD video recording and ISO sensitivity up to 12,800. A notable feature of this camera is its integrated GPS sensor for location-tagging of still images. The Alpha SLT-A55 boasts two major improvements over the Alpha SLT-A33, namely: a 16.2 megapixel Exmor APS HD CMOS sensor (the SLT-A33 sports a 14.2 megapixel sensor) and the ability to shoot at 10 frames per second (the SLT-A33 shoots at 7 frames per second). Otherwise, the two cameras sport the same features, including Sony's Translucent Mirror Technology and Anti-Dust technology.
The Alpha SLT-A55's 16.2 megapixel Exmor APS HD CMOS sensor allows it to capture both high quality images and high definition (1080/60i) video, boasting approximately 4,000 column-parallel analog-to-digital converters. Its Translucent Mirror Technology allows light to pass to both the SLT-A55's image sensor and Phase Detection AF sensor for simultaneous focus and 10 frame per second continuous shooting. Additionally, the Alpha SLT-A55's Anti-Dust technology utilizes a static-free coating on the sensor's low-pass filter as well as vibration which automatically dislodges dust from the sensor for consistently clear images.
