This Three-Axis Hot-Shoe Bubble Level from Vello mounts on the hot shoe of standard 35mm SLR cameras. It allows you to quickly and precisely align the camera on three planes, for maximum accuracy in mounting your camera in relation to horizon lines or other straight-line elements.
Since it doesn't have any way to lock itself down in the camera hot shoe, the wiggle room makes it very inaccurate.
This level is totally dependent on the cameras hotshoe. If the hotshoe is not level and most are not, this level doesn't work. I tired it on my Mamiya 645 pro tl which has the hotshoe on the left side of the camera body. Because the manufacturer never intended for the hotshoe to be used as a level, it would not work with this or any other level.
