B+W 102 ND Gray filter 37 ES mm

You can use the B+W gray filter to add contrast to your photos and reduce the amount of incident light without changing the color. Because the light on the sensor is reduced, longer shutter speeds (up to 2 stops) are possible, which can produce creative effects. The filter has a diameter of 37 mm and is equipped with a brass F-pro mount with thread on both sides. The filter also features crystal-clear glass and a matte black finish for extra protection against reflections
