High-quality gray filter with haptic feedback mechanism. Control the shutter speed in most lighting conditions. Ideally suited for filmmaking. The preset stop range prevents the possibility of cross-polarization. No vignetting up to a focal length of 16 mm. The haptic feedback mechanism ensures precise handling. Built-in filter protection with water and dust-tight sealing. ND filters extend exposure time. A neutral density filter (ND filter) or gray filter blocks a portion of the incoming light. With a gray filter, you can significantly extend the exposure time, achieving effects like blurred water or preventing overexposure in bright sunlight with an open aperture.
