Sony's announcement of the three Alpha line cameras just came today -- but we're already seeing plenty of them. Pocket Lint's got a fairly extensive hands-on with the Alpha 500, which boasts an Exmor CMOS 12.3-megapixel sensor, an ISO range of up to 12,800, with a four frames per second continuous shooting. It also packs an HDR shooting mode, and an HDMI output. The Alpha 500 will be out in October, and it will run you $750. There's one more shot after the break -- hit the read link for the full set.
