LEE Filters 4 x 5.65" ProGlass CINE IRND 1.8 Filter (6-Stop)

The LEE Filters ProGlass CINE IRND 1.8 Filter (4 x 5.65") is a professional neutral density filter designed to deliver precise exposure control while maintaining consistent color reproduction for digital cinematography and photography. Featuring a 1.8 optical density and 64x filter factor, this filter provides a 6-stop exposure reduction, allowing filmmakers to achieve their desired exposure settings even in bright lighting conditions.

By reducing the amount of light entering the lens, the ProGlass CINE IRND filter enables cinematographers to work with wider apertures and slower shutter speeds without overexposing the image. This added flexibility makes it easier to achieve shallow depth of field, maintain creative control over motion blur, and preserve a consistent visual style across changing lighting environments.

Engineered specifically for digital imaging sensors, the filter is designed to provide nearly uniform attenuation of both visible and infrared light. Digital sensors can be particularly sensitive to infrared contamination, which may introduce unwanted color casts, especially in darker areas of an image. The ProGlass CINE IRND filter helps minimize these effects, supporting more accurate color reproduction and consistent image quality when working with strong neutral density filtration.

Constructed from high-quality, scratch-resistant optical glass, the filter is designed to maintain excellent image clarity and color fidelity throughout professional production workflows. Its precision optical construction helps preserve fine image detail while providing reliable neutral density performance, making it suitable for demanding cinema and photography applications.

The filter features a metallic black rim designed to reduce unwanted reflections along the edges of the glass. Measuring 4 x 5.65", it is intended for use with compatible professional cinema matte boxes and filter holders that accommodate this standard filter size.

Combining 6-stop light reduction, infrared attenuation, scratch-resistant optical glass, and a reflection-reducing black rim, the LEE Filters ProGlass CINE IRND 1.8 Filter offers a dependable solution for filmmakers seeking precise exposure control and consistent color accuracy in professional digital productions.
