NEEWER 67mm MRC Variable ND Filter ND2 ND400, Neutral Density Adjustable (0.3 to 2.7, 1 9 Stops), Multi Layer Coated Optical Glass, Water Repellent & Scratch Resistant Ultra Slim

Variable ND filter: The variable ND filter ND2-ND400 reduces the amount of light that reaches the camera sensor by 1-9 stops, allows you to take photos in different conditions with longer shutter speeds and larger apertures, perfect for capturing rivers, waterfalls, light streaks and other moving objects with dynamic motion blur Excellent quality construction: optical 4-element glass with a Japanese NITTO polarising film ensures optimal neutrality as well as precise contrast and colour reproduction Multiple nano coatings: Multiple nano coatings with a minimum light reflection of 0.1% block ultraviolet rays of 300 nm - 380 nm and reduce stray light and ghosting. They also protect the filter from water, oil, dust and scratches Ultra-thin metal frame: the ultra-thin 9.5 mm metal frame with precise threads is easy to mount and prevents vignettes with wide angle and telephoto lenses Notes: 1. A dark cross pattern may occur when using certain lenses and focal lengths. This is normal and temporary for variable ND filters. 2. The minimum and maximum ND effects differ depending on the actual situation. 3. For long exposure times, please purchase ND1000 or ND2000 filters. 4. For 67 mm ND filter, use a 72 mm lens cap
