About Sony A57
In an age of camera inflation, the Sony A57 is a solid, middle-of-the-road camera, ideal for enthusiastic amateur photographers who want a reasonably priced camera that will produce high-quality images without requiring too much technical expertise.
The external appearance of the Sony A57 is similar to that of a DSLR, such as the costly A65, but it is actually an interchangeable lens camera. It offers 16.1 megapixel shots with 18-55 millimetre zoom, including continuous autofocus using 15-point phase-detection and three cross systems. It is also designed for quality burst shooting, at 12fps. As a result, the A57 is ideal for photographers looking for effective multi-shot functionality. This is especially useful for shooting sport, wildlife or hyper, bouncy children. The combined functions of the A57 guarantee that you can easily take a series of shots that, thanks to autofocus capability, will produce sharp and clear images.
Of course, for many casual photographers, size is an important consideration. You don?t want to have to drag a large, heavy camera around on your holiday. The advantage of Sony?s translucent mirror technology is that it operates on a simpler design than the traditional DSLR. As a result the A57, measuring 132.1 X 97.5 X 80.7 millimetres and weighing 539 grams, is smaller and lighter than many other models.
Camera shake is a common problem among amateur photographers and sometimes the only solution is to buy a specialist lens. Sony outstrips its competitors on this front by incorporating sensor shift image stabilisation into its entire range.
