I want to start doing some videos on my E-PM1. Would it be a better idea to use the Panny 14-45 instead of the Olympus 14-42? Both seems to focus fast and silent but as I understand it, the Olympus' IBIS doesn't work during video mode. What other lens would be a good choice for videos that's around the same (read: cheap) price range as the kit lens? I'll most likely use C-AF unless there is a lens out there with a very precise manual focusing ring.
