With Panasonic announcing a professional video camera (AG-AF100) this weekend at the NAB (National Association of Broadcasters) convention that uses a large sensor (4/3), the window for the DSLR video craze has begun to close. It was only a matter of time before the big video players made their move to protect themselves, and Panasonic is just the first of many such announcements we'll see in the coming year. So, the DSLR makers can up the ante and really turn on the burner of video features to try to stay ahead and piss us still photographers off completely, or they can get back to what they used to do: innovate in still photography.
