PMA 2007: Sony opened their PMA show with a press launch for two new Alpha DSLR prototypes and a selection of lenses. Details about the new DSLRs are sketchy to say the least. On display behind glass was a high-end prosumer model, apparently more advanced than the current A100 DSLR, and a professional level camera, with a pentaprism that looks like it came straight from a Pentax medium format camera. The Sony spokesperson was unclear about which model would be released first, but confirmed that one of them will definitely be released before the end of 2007. Also on show were 8 lenses (again mockups rather than production products) covering a wide range of focal lengths. These are all new Sony designs and not rebadged versions of old Konica Minolta lenses. I’ve posted 9 photos after the jump.
