For what a Canon tripod ring costs, your going to have a decent payment toward a good tripod head.


Arca-Swiss makes an L Bracket for what your talking about, but then I think your looking for cheap options. It is $248.99.


Without a good tripod ring or L bracket, it will be tough to get a good stable head. I bought the Acra Swiss Z1 before I went to Yellowstone this year, it worked great, but to do what you are talking about was difficult with it. The ball would tilt enough to change orientation but it wasn't to smooth this way, it took allot of playing. I have a Gitzo head that will invert to any angle, I bought it for macro work but for me I didn't think it was stable enough.


Have you thought about this though, even if you get the tripod ring on a 35mm your are going to be very close to your ball and pod. Will there be enough room to invert the camera without it hitting something.


I would think any good L bracket that can attach to your camera on one side and the plate on the other would work. This is the cheapest option I could find just now on B&H
