This is an excellent lens not only for video but for stills photography too. I think this is the heaviest lens in the Panasonic arsenal but it's not too heavy on the G series which I use for this lens. I don't like it on the GF1 where it really becomes front heavy. OIS works well also allowing you to make images at low shutter speeds.
