Verdict

The Sony Alpha DSLR-A550 is a mid-range camera featuring a 14.2-megapixel APS-C Exmor CMOS sensor, a 9-point autofocus system, and an ISO range of 200–12,800. Key characteristics include a unique dual Live View system consisting of a fast phase-detect secondary sensor mode and a high-accuracy manual focus check mode on the main sensor, alongside a tilting 3.0-inch LCD screen with 921k-dot resolution. Its main pros are the effective SteadyShot INSIDE sensor-shift image stabilisation that works with any lens, a fast continuous drive speed of up to 5 fps (reaching 7 fps in Speed Priority mode), and an outstanding battery life of up to 950 shots per charge when using the optical viewfinder. However, the camera has some notable cons, including a complete lack of any video recording capabilities, over-processed default JPEG outputs that lack subtlety, and an optical viewfinder that is relatively small and tight for spectacle wearers.
