Vimeo member Ragnar tackles the DIY suction cup camera mount for his GH2. There are much cheaper suction cup mounts, first posted here: http://cheesycam.com/diy-double-and-quad-suction-camera-car-mounts/, but Ragnar decided to go with a slightly more expensive Suction mount with articulation so that it can mount on not-so-completely flat surfaces such as hoods, windows, and other car panels. I'm sure we all don't believe in specs, but the one he's chosen states that it's rated for 132 lbs, so even if it's half true, that's more than suffice for a small GH2. So far it looks like he's fairly comfortable with the setup, trusting it to about 50mph (with a backup safety strap attached of course). For GoPro owners, this inexpensive setup should have no issues with the mini lightweight camera.
