Test footage shot on my 5D Mark II, 15mm 2.8 Fisheye with a $25 DIY top handle mounted on the hotshoe (see picture in the right column). Overall it wasn't bad for the first try, but the whole setup is really light, so the lack of inertia creates some unnecessary camera shake.
I'm going to work on it some more then post a tutorial on how to build one.
Thanks to the skaters/guinea pigs for the day. In order of appearance: Will Flores, Roman, Austin Lewis and Jeet.
