Sony intros Alpha DSLR concepts, 'ultra-compact' interchangeable lens model included

PMA is just kicking off in earnest down in Anaheim, and it looks like Sony has arrived in a big way. Looking to make a splash in a DSLR world dominated by Canon and Nikon, the outfit has brought a few of its best and brightest concepts to SoCal. Up first is an ultra-compact "interchangeable lens" concept, which is no doubt Sony's attempt to get in on the fledgling Micro Four Thirds game before it blows up big. Few details on the device are available, but we'll be doing our best to pry whatever specifications we can from the booth representatives in short order. Moving on, there's a conceptual model of the Alpha A700 replacement, complete with an Exmor APS HD CMOS sensor that promises full AVCHD video capabilities. There's also a prototype of a Super Telephoto Lens (500mm F4 G) as well as a prototype Distagon T 24mm F2 ZA SSM, which ought to make wide angle junkies drool profusely. The company's also dishing out a raft of accessories, including underwater housing devices, HD lenses and output cables, tripods / accessory packs and a Compact PictureStation photo printing kiosk. Stay tuned for some hands-on action from the show floor.
