"the new OLED viewfinder and 20 megapixel resolution and handy Lock-on Autofocus mode are improvements, which makes the much cheaper Sony A58 a real bargain.
Just like the rest of the SLT family, the Sony A58 turns conventional design on its head to provide what is in many ways a better user experience than traditional DSLRs can achieve, at a very competitive price point that Canon and Nikon must surely be worried about. The A58's excellent OLED electronic viewfinder offers enough enough resolution and real-time feedback to take on a more conventionaloptical viewfinder, while the translucent mirror and EVF combination provides fast auto-focus for both stills and video and 100% scene coverage, although the burst shooting mode is disappointingly slower and more limited in buffer size and file format than previous SLT cameras."
Lots of new goodies in this one: A new 20 Megapixel sensor, a Oled SVGA (800x600) EVF, lock-on focus feature, and some 'Auto Object Framing' mode, but no built-in GPS, something that was available on the older A55. The A58 well replace both the A57 and A37 cameras, and will come with a new kit lens, the video friendly DT 18-55mm F3.5-5.6 SAM II. Availability is set for April 2013 in Europe, TBA for the rest of the world.
