I've been interested in this type of lens too. Does the old rule of using a tripod if the shutter speed is longer than the inverse of the lens length still apply (200mm = 1/200 sec = fastest to handhold?) Or does the fact that the lens is physically shorter than the old prime long lenses were change the equation. I realize image stabiliztion will help regardless, just want to know how the lens zoom affects shutter speed on these newer lenses. Thanks!
