Proving how serious they are about the Lumix GH1 as a video camera, here's Panasonic's new Micro Four Thirds camera with the optional accessory mic. I also found out the 14-140mm "HD" zoom lens was developed to silent so as not to interfere with the video sound recording. They said it took quite a while to get the lens so that it was quiet enough to use while shooting video. That's also part of the reason the lens is a 10x zoom - so that it will cover 90% of the needs of most people shooting video. Most people won't ever need to use another lens while shooting video with the GH1.
