Breakthrough Filters X3 ND Filter
Breakthrough Filters already produces a high-quality six-stop ND filter, and the firm has now added this 10-stop model to its range. It will extend a 1/500-second exposure to two seconds – long enough to capture smooth clouds and water even on a bright sunny day. As part of the X3 range, this screw-in filter features a brass thread which is softer than the metal used for the barrel of your lens, to help avoid damage. Ultra-thin glass is used to reduce vignetting.
