We took our industry leading X4 ND filter and applied the same proven technology to the graduated neutral density filter, manufactured it with tempered SCHOTT B270® optical glass made in Germany, and the result is the X4 GND – the world’s sharpest and most colour neutral GND, guaranteed.

Incredible Durability.

Another benefit is that the optical surface does not degrade over time or with exposure with corrosive elements such as salt water and sand, common conditions for outdoor photographers.

By using SCHOTT B270 optical glass, the X4 resolves critically sharp and as it is tempered glass it is incredibly strong. The X4 square's  impressive structural hardness also prevents warping, a common issue that develops over time with traditional resin filters, especially when not stored flat. Slightly warped filters can add slight distortion noticeable on wide-angle full-frame setup.

State-of-the-art Coatings.

Traditional CR-39 resin had exceptional sharpness performance if the surface was in mint condition, however CR-39 proved to be a poor material for accepting coatings, and therefore the industry leading CR-39 GNDs by Singh-Ray and Lee are without MRC or nano coatings.

Each X4 square has our state-of-the-art MRC16 and nanotec coatings technology applied to both sides of the optical surface. This reduces surface reflection and nano coatings make handling and cleaning the surface of the glass easy. The nanotec coatings also let the X4 squares glide smoothly in the holder.

The edges of each X4 square are then milled down smooth, and an outer-layer of protective coating is applied along the edge of the glass.

Diamond Cases

Each X4 square filter comes with a protective diamond case. They're durable, easy to use, prevent damage when in your bag and they have unique colours so you know which you're using.
