Sony will be taking on Nikon and Canon with one behemoth of a camera, the mirror-less 24.3 megapixel A77. Rumored to be priced at just $1000, the new camera will feature a 19 point AF sensor, up to 16000 ISO sensitivity, 12 fps shooting, 1080p video, 1/5000 shutter speed, OLED viewfinder, and a battery life good enough for just over 500 shots.
