Sony APS-C DSLR with in-body stabilisation, quick AF live view, and 5fps burst shooting.
The Sony A550 is a 14.2-megapixel APS-C DSLR from Sony's A-mount system, featuring a unique quick AF live view system that maintained fast phase-detection autofocus during live view shooting. This was a genuine innovation at a time when most DSLRs switched to slow contrast-detection AF when using the rear screen.
The camera shoots at 5 frames per second in continuous mode with reliable autofocus tracking, making it capable for action photography. The sensor delivers good image quality with reasonable high-ISO performance for its 2009 generation. In-body image stabilisation works with any A-mount lens, a significant advantage over competing Canon and Nikon systems.
Build quality is solid consumer-grade with a comfortable grip, clear rear LCD, and intuitive menu system. The camera accepts the full range of Sony and Minolta A-mount lenses, providing access to an extensive optical ecosystem. The tilt screen was a useful feature for low-angle and waist-level shooting compositions.
On the used market, the Sony A550 offers very affordable entry into the Sony A-mount system with in-body stabilisation. For beginners wanting to explore photography with a capable DSLR, or A-mount users needing a backup body, it delivers solid performance at prices that make it essentially risk-free to try.
