The Rycote 042902 InVision Video (1/4 Adapter) holds microphones with diameters from 19-25mm, while protecting against camera motor noise and vibrations. The InVision Video uses the patented Lyre Suspension webs with a molded grip design to prevent your mic from slipping or twisting. For ease in finding the right mounting position, the InVision Video rotates freely 360deg. on a slotted 4" (100mm) mounting bar. The cradle can slide freely on this slotted bar to keep your mic out of the shot.
