Sony unveiled the Sony Alpha SLT-A57K 16.1 MP Exmor DSLR HD Video Camera with a CMOS Sensor, Translucent Mirror Technology, 3D Sweep Panorama and 18-55mm Zoom Lens. The midrange d-SLR features a 16-megapixel, APS-C-sized sensor and is positioned to compete with Canon's EOS Rebel T3i and the Nikon's D5100. It can be pre-ordered on amazon already, for a price of $699.
Sony has announced the SLT-A57, a replacement for the original A55 fixed-mirror, electronic viewfinder DSLR. The A57 still features a 16MP sensor and LCD viewfinder but incorporates them into essentially the same body as the more expensive A65. Use of the latest Bionz processor means the A57 offers a wider-than-ever selection of photographic features and image processing modes. There's also an optional HVL-LE1 video-lighting LED panel.

Sadly, neither the Atomos Ninja 10-Bit Uncompressed to Apple ProRes Field Recorder nor the Black Magic HyperDeck Shuttle Raw Video HDMI Recorder supports 50frames and 60frames in Full-HD (1080p), so we are limited to the internal recordings on the camera. The Sony Alpha SLT-A57 supports AVCHD 2, so the video output should be decent. We are looking forward to example videos and will keep you posted on updates.
