Cokin U300-01 Square Filter Full ND Creative Kit

The Cokin U300-01 Square Filter Full ND Creative Kit provides photographers and videographers with a practical set of neutral density filters for controlling exposure in a variety of lighting conditions. The kit includes ND2 (1-stop), ND4 (2-stop), and ND8 (3-stop) filters, which reduce the amount of light reaching the sensor without altering color balance. This allows you to use slower shutter speeds for motion blur effects — such as silky waterfalls or streaked clouds — or shoot with wider apertures for shallow depth of field even in bright sunlight.

Each filter is manufactured using Cokin's C39 optical resin, a material chosen for its balance of optical clarity and durability. The square format is designed for use with the Cokin L (Z) Series filter holder system, which accepts adapter rings for a wide range of lens diameters. This modularity means a single set of filters can be used across multiple lenses, making the kit a cost-effective investment. The filters can also be stacked in the holder to combine their light-reducing effects when conditions demand even greater exposure control.
