C100 Z-Bands are elastic bands that help support your
C100 Z-Finder. The C100 Z-Bands attach to your camera via a screw hole on the film panel included on the left side of the camera and then clip into two ball sockets on the Z-Finder itself. These Z-Bands add tension and support to the mount so the LCD screen and viewfinder can be set at any angle. Without the use of the Z-Bands, the hinge on the LCD screen cannot support the viewfinder (in any tilted up positions). C100 Z-Bands are compatible with the C100 Z-Finder only. They are not compatible with the DSLR Z-Finders or the Blackmagic Z-Finder.
