The Eyepiece leveler is a key component of the Master Cinema Series Studio Cam bundle. It allows the EVF to remain relatively level while tilting the camera up and down when mounted to a tripod. The leveler attaches to our standard EVF knuckle via the quick release bracket and allows you to telescope the EVF in and out to obtain the best position for use. The base bracket attaches to O'Connor tripod heads threaded for leveler use. Leveler includes tripod head and EVF bracket of choice. Designed to work with the Master Cinema Series EVF knuckle and camera cages.
