How to achieve superior control over your photography in bright light conditions The answer lies in our professional 67mm Circular ND64 6-Stop Lens Filter Plus+. This high-quality filter offers a fixed 6 f-stop light reduction, empowering you with enhanced control over long exposure and depth of field techniques even in the most luminous environments. By limiting the amount of light that enters your camera, this filter allows you to utilize wider apertures in bright light, creating a stunningly shallow depth of field effect without the risk of overexposing your images. The Plus+ range of our filters boasts a 20-layer nano-coating, ensuring not only easier cleaning but also superior protection against water, oil, and scratches. These multiple layers also enhance maximum light transmission and provide a more consistent transmission curve, resulting in truer light reduction and more accurate colors.
