DSLRs tend to have longer refresh cycles than oh, we don't know, phones with RAZR in the name, but every shooter must eventually go to heaven nonetheless. About a year and a half after introducing the Alpha A55 translucent mirror camera, Sony's putting that model out to pasture to make way for its replacement, the Alpha A57. This time around, Sony's bumped the ISO to 16000 and boosted the continuous shooting rate from 10 frames per second to 12. It's also rolling out some improvements to the 15-point autofocus system, including enhanced object-tracking and quick AF in Full HD movie mode. Like the A55 before it, the A57 packs a 16-megapixel APS HD CMOS sensor, though this guy records 1920 x 1080 video at 60p, 60i and 24p/25p. It also packs the relatively new Bionz imaging engine introduced with Sony's fall 2011 models. Also on board: effects like Auto Portrait Framing (it is what it sounds like) and Clear Image Zoom, which promises an effective two-fold increase in focal length. Design-wise, the A57 takes some cues from the A65 , and sports a tilting, 921,600-dot LCD. It'll start at $699 for the body only when it goes on sale next month, though it will also be offered as a $799 kit with an 18-55mm lens. Until then, we've got official press shots below and the PR just past the break.
