Sony's newly announced a7S is shaping up to be a video behemoth. Yes, this video really impressed me. With its light weight and quality sensor, if they hit the right price point Sony could have the camera I would be tempted to leave Canon for. "Features newly developed, wide dynamic range sensor with awe-inspiring sensitivity. Joining the acclaimed α7 and α7R family of the world's smallest full-frame interchangeable lens cameras, Sony's new α7S model puts extraordinary sensitivity, low noise and spectacular 4K video quality into the hands of professional photographers and videographers."
