Sony A33 and A55 - differences

The Sony A55 is an interchangeable lens camera that uses Translucent Mirror Technology to offer high-speed shooting and a smaller body size. Compared to a conventional DSLR camera, Translucent Mirror Technology utilises a fixed, translucent mirror that splits the optical pathway between the main image sensor and a separate phase-detection autofocus sensor, and offers a simplified mechanical design that enables the camera to be smaller. The In many ways the Sony A55 is very similar to the company's more conventional mid-range DSLR lineup, with models such as the A looking almost identical from an external point of view. The A55 is very different internally, though, dispensing with an optical viewfinder in favour of an electronic version, and using a fixed semi-translucent mirror instead of the moving non-translucent mirror of a DSLR. The translucency of the A55's mirror means that enough light can pass through it to the sensor to allow it to remain fixed in place at all times, with the ability to reflect some of the light onto a phase-detection auto-focus array that sits in the top of the A55 body.

Where the A55 truly excels is with its super-fast shooting capability. Whereas most cameras at this level are capable of shooting a few frames per second, their autofocus systems tend not to be able to predict focus or track moving subjects. In addition, it also has the ability to continuously re-focus for impressive accuracy. The AF system offers a point array with three cross-type sensors towards the centre for more accurate use in both portrait and landscape orientations. Many up-to-date websites and programs can utilise the data intelligently in a number of ways too. Once the image is framed and the focus set a full shutter press will flip the mirror upwards and out of the way before the shutter itself fires to expose the image sensor for the time period the shutter is set at for the final image capture. The back of the camera also offers a standard d-pad arrangement for menu navigation purposes, with a variety of one-touch buttons dotted about elsewhere to control movie, exposure compensation, exposure lock, D-Range Optimiser and depth-of-field preview.
