This is the Sony α Alpha SLT-A77:
It features the latest Translucent Mirror technology from Sony, and has an articulating rear LCD preview screen.
If you intend to do tethered shooting with the A77, you might want to wait a bit until Sony officially releases a firmware update to enable tethering on the A77. This is a slightly disappointing piece of news as the older A700 had this feature.
I find that the A77 doesn’t do high ISO very well.
Reviews
Popular Photography: “Sony has, once again, radically changed the world of DSLRs with its A77. Plus, it has done so without compromises in the shooting experience or in image quality. The A77 now reigns supreme over APS-C format DSLRs. Neither Canon’s EOS 7D nor Nikon’s D300s can match the A77’s AF speed or resolution. While the Canon 7D does beat the A77 in its noise performance and holds more resolution at the highest ISOs, the A77 ultimately beats it for the overall package, including the video-shooting experience and the versatility of the articulated LCD.”
