During stunts which can damage a lens, the Schneider 5" Round Optical Flat Clear Glass Filter protects expensive front elements and other filters while providing the truest image, free of unwanted color shifts.
May be left on at all times to protect your valuable lens
Made from Schneider's clear optical glass, these filters minimize or eliminate the need for laboratory color correction caused by filter variations
Both the front and rear surfaces of these solid-glass (non-laminated) filters receive Schneider's hard anti-reflective (AR) coating, which measurably improves light transmission
