Verdict

The Sony Alpha A550 is a mid-range DSLR featuring a 14.2-megapixel APS-C CMOS sensor and a high-resolution 3.0-inch 921k-dot tilting LCD screen. Key characteristics include a dual live view system with dedicated phase-detect autofocus, a fast burst rate of up to 7 fps in Speed Priority mode, and built-in SteadyShot INSIDE image stabilization that works with the included Sony DT 18-55mm f/3.5-5.6 SAM kit lens. Main pros include its class-leading live view autofocus speed, excellent high ISO performance for its era, and effective in-body stabilization. However, it lacks video recording capabilities, features a relatively small optical viewfinder with 95% coverage, and has been noted for having limited customization options and inconsistent JPEG color accuracy.
