Z-Bands are compatible with the Z-Finder Pro and V2. They are not compatible with the Z-Finder Jr. The Z-Bands are elastic rubber bands to help hold the Z-finder in place. The Z-bands must be used with a standard Z-Finder mount. They are an added security measure but cannot be used alone to hold the Z-Finder on the camera. The Z-Bands stretch around your camera and fit into the small ball sockets in the corners of your Z-Finder body.
Please contact firstname.lastname@example.org if you need Z-Bands for the Canon C100 Mk I
The Z-Bands will not work with the Canon 7D due to the specific shape and curvature of the camera.
