The Polaroid Optics 40.5mm Neutral Density Filter (ND 0.6) is a professional-grade filter designed to enhance your photography experience. It darkens images to prevent a washed-out look, providing you with ultimate control over exposure, shutter speed, and color integrity. This filter allows for wider aperture settings, keeping your subject in focus even in complex lighting conditions. It provides powerful light filtration, reducing ISO by 1/8 and offering +2 stops of neutral density per shot. Ideal for outdoor photography, it prevents overexposure and ensures optimal focus and depth-of-field control for wide landscapes. The filter has a minimal effect on optical quality, allowing you to balance brightness and capture movement without affecting color or optical detail. It is double-threaded for easy filter stacking and is compatible with all 55mm lenses. Please verify your lens thread size based on the ‘Ø55' marking on the lens barrel or underneath the lens cap for a perfect fit.
