The EVF Mount Bracket for C100's attaches to the top handle of the C100 and C100 Mark II camera via a 1/4" 20 screw. There are two 1/4" 20 screw holes alternating with two 3/8" 16 screw holes (positioned 1/2" apart) along the top of the bracket for easy accessory mounting. It positions a rod port at the front of the top handle for mounting the Axis Mini or any 15mm rod accessory. It also slides into the open coldshoe on the C100 camera handle for extra security. An additional coldshoe mount is built into the bracket for your accessories. This bracket is compatible with the C100 and the C100 Mk II. Does not work with C100 Z-Finder.
