The Marumi 40mm UV Digital High Grade Filter is a precision-engineered lens protection filter specifically designed for digital cameras. This 40mm filter features advanced multi-coated optics with ultra-low reflection technology that minimises internal reflections off your camera's CCD and CMOS sensors, delivering sharp, clear images without colour cast. The filter blocks ultraviolet rays with a wavelength of 390nm or less, effectively reducing haze and glare whilst maintaining contrast and sharpness, particularly useful for coastal and mountain photography. With its thin frame design and lightweight construction, it avoids vignetting even with wide-angle lenses and provides durable lens protection from dust, scratches and physical damage.
