The DSLR-A900 is Sony's full-frame flagship and a true photographer's camera. It offers a great viewfinder, in-body image stabilization and, at the time of its launch, at 24.6 MP the highest nominal resolution of its class. The camera is capable of stunning results at up to ISO 400 (and is fine at ISO 800-1600 as long as you're not printing posters), and it is incredibly fast and responsive in use.
