Besides the fact that it's quite a "fumbling" the objective, should get a clean zoom during video, the lens is not available in either of the focus still on the light output, a figure miracle. In addition, the autofocus is not very accurate, ie, the lens focuses on a video zoom by! The processing of the lens is great and very easy, but unfortunately it does not keep what it promises. Each push of a compact camera without interchangeable lens (eg HX100V or FZ150) is faster, more accurate autofocus and in particular easier to use. Too bad, I was really looking forward to the lens.
