There's nothing like the Sony Alpha a7... well except the higher megapixel a7R and the new film-loving Alpha a7S. Beyond that trio of tightly knit siblings, there are no other full frame sensor, DSLR-style cameras on the market that are nearly this small and light. The a7 is the natural upward evolution of the Sony NEX APS-C interchangeable lens cameras, and the a7 has grown up Alpha menus, plenty of dials and controls and of course, that big 24MP full frame sensor. This mirrorless camera offers continuous autofocus for 1080p video recording, Sony's fast new BIONZ X processor, excellent image and video quality and a quality weather sealed body for $1,700 ($2,000 with kit 28-70mm lens). Is your big DSLR weighing you down or are you ready to move up from a Sony NEX camera? If so, check out our in-depth review pronto.
