Ten frames per second with continuously active AF is no mean feat, especially in a camera costing £700. Whether it is worth the loss of the optical viewfinder is another matter

Images: Canon EOS 550D, Pentax K-r

Sony has effectively introduced a new type of camera and as a result the direct competition is not clear. In fact, only the Canon EOS-1D Mark IV can match the Alpha 55’s 10fps, and it is only in the continuous JPEG file burst where the Canon camera outshines the Sony model. However, the Mark IV is aimed at the professional-level user.

While many features put the Alpha 55 up there with higher-level cameras, its build and size align it with more entry-level or even micro-system cameras such as the Panasonic Lumix DMC-GH2. In reality, it falls somewhere between the two, such as a high entry-level, or low-end enthusiast level, model. With this in mind, the Pentax K-r, with its respectable 6fps shooting rate, and the Canon EOS 550D are currently the closest competition.

The Alpha 55 has a particularly strong video mode and features, but image quality is slightly better in the Canon model.
