About this product
The B + W 40.5mm Master 803M ND 0.9 3-Stop MRC Nano Neutral Density Filter is a precision optical filter designed for photographers and videographers to control light intake without altering color balance. Crafted from high-quality, finely ground glass with a seven-layer multi-coating on each side, it reduces light by three stops while minimizing reflections, glare, and maintaining image contrast. This allows for creative long exposures in bright conditions, producing smooth motion effects like flowing water or empty streets. The filter's durable construction resists dirt and water, ensuring easy cleaning and consistent performance across digital and analog cameras. It supports selective focus techniques by enabling wider apertures in bright environments, ideal for portraiture and cinematic video work. Not suitable for direct solar viewing due to UV/IR transmission.
