The K&F Concept Square Ultra Slim filter is a square ND64 filter for camera lenses, with a thickness of 2.3 mm and Japanese optical glass. It reduces exposure by 6 stops, preventing overly bright, washed-out images and allowing longer exposure times to capture motion.
The 20-layer multilayer coating, with a metal alloy on both sides of the clear glass, delivers neutral image performance without color shifts or infrared contamination and reduces reflections and ghosting. The filter is scratch-resistant and repels water, oil, and dust.
