Cokin H3H3-21 Expert ND Creative Filter Kit (M/P Series)

The Cokin H3H3-21 Expert ND Creative Filter Kit is a comprehensive package for photographers who want precise control over exposure and light balance in their images. Built around Cokin's M (P) Series system, the kit arrives ready to shoot with a filter holder, three neutral density filters, and four adaptor rings. The full ND4 filter provides a uniform 2-stop light reduction across the frame, useful for slowing shutter speeds to blur motion in waterfalls, streams, or crowds. The two graduated filters—a GND4 (2-stop) and a GND8 (3-stop), both with hard-edge transitions—are designed for scenes where the sky is significantly brighter than the foreground, letting you darken just the upper portion of the frame to achieve a balanced exposure in a single capture.

The included P-Series filter holder accepts the rectangular and square filters and attaches to your lens via one of the four supplied adaptor rings in 52mm, 55mm, 58mm, and 62mm sizes. The square filter format is a key advantage over screw-on circular ND filters because it allows you to slide the graduated filters up or down to position the transition exactly where you need it relative to your horizon line. This kit is well-suited for landscape, architectural, and outdoor photography where managing dynamic range in-camera is preferable to relying entirely on post-processing techniques.
