I have 2 z8's. The first one has a SmallRig L which is fine and designed for use with the video outs, but is not very rigid, even in the collapsed form when in vertical mount. The small rig allows the same adjustments but instead the registration pin is movable. This allows for a single piece of metal to be the entire L bracket. It is the most rigid L bracket I have used since I moved to digital. It is also significantly smaller and lighter than the SmallRig, plus it still has a QD port like the SmallRig. I never would have purchased the SmallRig had this been on the market at the time.
