The new Sony Alpha A55 and A33 have as great novelty the Traslucent Mirror that consists of a semitransparent glass next to the fixed mirror that distributes the light between the sensor itself and the phase detection AF system, increasing the shooting speed and the focus.
Unlike conventional DSLRs, the translucent mirror technology in these new cameras uses a fixed translucent mirror that divides the optical path between the main image sensor and a phase detection autofocus sensor.
The Alpha A55 comes with a 16.2 megapixel APS-C CMOS sensor and bursts at up to 10 frames per second (35 in JPEG and 20 in RAW). While the Alpha A33 has a 14.2 megapixel sensor and offers bursts of up to 7 shots per second.
Both models offer a range of ISO 100 to 12,8000, high definition video recording (AVCHD 1,080i) at 30 images per second, 1.15 megapixel electronic viewfinder, 3-inch articulating LCD screen and 921,000 pixels and have a system 15 point focus.
For its part, the most advanced model, the Alpha A55 includes a GPS receiver to geolocate photos and use this information in applications such as iPhoto.
