I tried this, on a Manfrotto 3221W tripod with 3130 head, tilting the camera 90 degrees down to view the floor underneath. Very interesting! The image has a small, roughly circular motion which suggests to me the optical stabilizer assembly may be swinging loose. I tilted up to shoot horizontally at the same zoom setting and got a rock solid image. In both cases, image stabilization was off.
I will guess that Panasonic did not test this camera pointing straight down. I suspect the optical stabilizer (which has to move quickly when in use) sits on some pivoting element that is braced when off and the camera is held normally, but has some freedom to twist when pointed straight down.
You may have to resort to using a mirror at 45 degrees to shoot vertically. If you use a good quality, clean front-surface mirror, the image quality will not be affected. Obviously it would have been better if that wasn't necessary. By the way I think there are 45 deg. mirrors available to thread on to DSLRs & video cameras, sold as "spy lenses" to shoot sideways from where the camera seems to be pointed.http://photojojo.com/store/awesomene...aphy-spy-lens/
