|Sony SLT (single lens translucent) Alpha A55 is a hybrid, compact-like camera that is capable of providing full-time DSLR-style phase-detection autofocus by incorporating a fixed translucent mirror designed to redirect a portion of the captured light to the autofocus sensor. With the use of this translucent mirror, the A55 is able to shoot 1080p HD videos with full-time AF and Phase-Detection.
A55 features 16.2 megapixels which is Sony's highest-resolution APS-C format sensor yet. This 16.2-megapixel Exmor APS HD CMOS sensor is combined with Sony's BIONZ image processing unit which simultaneously upgrades the video and image quality. The captured 1920 x 1080p HD movies are recorded in AVCHD format in 59.94i video (60i) frame rate (sensor output: 29.97fps). Videos can likewise be shot in QuickTime Motion JPEG at 1440x1080 resolution in 29.97p or 25p and in 640x480 resolution at 29.94fps. For low-light photography, A55 offers ISO sensitivities from 100 up to 12800. Shooting images with ISO 25600 is likewise possible with the A55 but only in multi-shot NR mode (JPEG).
Sony’s A55 comes with a Tilt/Swivel 3-inch 921K dot TruBlack™ LCD screen (180°) that enables you to shoot low-angle movies with ease. With this LCD screen, you can view menus and liveview images even under a bright sunlight as it has a special resin layer that helps surpass reflections. Sony α SLT A55 features a newly developed 15-point AF array that gets 30% of the light which is being transmitted by the semi-translucent mirror that increases continuous shooting to 10fps. A55 is equipped with a built-in Super SteadyShot in-camera image stabilization that enables you to shoot blurred-free handheld images allowing up to four stops advantage. It likewise features a built-in GPS receiver that allows you to Geotag your photos. This GPS receiver has the capacity to record geo-location data which can be used with those geotagged data with Google Earth and Google Maps. Among the amazing features packed with the A55 are Auto HDR & Sweep Panorama features. The camera measures 124.4 x 92 x 84.7mm (W/H/D) and weighs approximately 15.27 oz.
