No, just different. If you turn AF on in the D7000 during video it will do this. You obviously have the option of doing it manually and avoid the buzzing. With the 7D it doesn't AF in video, your option is to hit the AF-ON button when you go out of focus or focus manually. When you hit the button it really brightens the screen and becomes distracting. Just as distracting as the buzzing sound. Just shows the tech is not there yet but really only the "mom and pop" shooters will care. They are the ones who will use this feature all the time.
