The Elements EVF Mounting System provides a secure mounting interface on all Elements top bracket while providing 4" of vertical adjustment and 6" of telescoping adjustment along the viewfinder axis. In addition to the linear adjustment, it also provides a rugged clutch that allows the viewfinder to be tilted to almost any angle. It will stay where you put it regardless of shooting environment.
All adjustments including clutch drag are easily adjusted on-the-fly without tools. Although the EVF clutch itself can be used with any camera system that can accept the 19mm tube clamp, because this is a Bomn Interface kit, it includes the additional Bomb Interface. The same clutch, with the addition of an interface, can be used with other EVFs.
