Tiffen 55mm WW IR Neutral Density 3.0 Filter

The Tiffen W55IRND30 is a 55mm WW IR Neutral Density 3.0 Filter. The high density blocks light emission of the visual spectrum into the camera, allowing you to photograph with a much slower shutter speed or at a wider aperture than required. The IR blocker allows for less Infra-Red pollution which has been attributed to long exposures on smaller crop sensors.
