This is an interesting lens. There is no optical image stabilization, and the lens extends when zooming, but it's sharp, lower weight than you would expect (not much more than some 24-105mm F4), and the price is decent at $1500. If you're shooting on a tripod this would be a great lens for video, as long as you're using autofocus. Manual focus is disappointing on this lens and the largest strike against it.
