Kondor Blue KB-FS-ND 4x5.65-Inch FullSpec NDFilter - 4-Stop

Kondor Blue 4x5.65-Inch FullSpec ND Filter

The Kondor Blue 4x5.65" FullSpec ND Filter is designed for professional filmmakers, cinematographers, camera operators, and production crews who need reliable exposure control without compromising image quality. Built for demanding cinema workflows, this full spectrum neutral density filter helps reduce light while maintaining clean, consistent color performance across different shooting environments. Whether working outdoors in harsh sunlight, balancing exposure between shots, or maintaining a preferred aperture and shutter speed, this filter is made to support a controlled, professional image from capture through post-production.

Unlike basic neutral density filters, the Kondor Blue FullSpec ND Filter is engineered to manage visible light along with infrared and ultraviolet wavelengths according to the filter strength. This helps reduce unwanted color shifts, IR contamination, muddy blacks, and magenta tones that can appear when digital cinema cameras are used in bright, high-IR or high-UV lighting conditions. The result is a more neutral and dependable image, especially for productions where color consistency and shadow integrity matter.

Constructed with premium SCHOTT B270 optical glass and housed in a rugged aluminum frame, the 4x5.65" FullSpec ND Filter is built to fit industry-standard matte box systems. The slim 0.08" optical glass and durable 0.16" aluminum frame provide professional handling while supporting long-term use on set. Corner grab tabs allow for faster and cleaner filter changes, helping reduce fingerprints, smudges, and unnecessary contact with the glass during production.

Available in multiple ND strengths, this filter line gives filmmakers the flexibility to choose the right density for the shooting condition. Options include IRND 0.3, 0.6, 0.9, 1.2, 1.5, 1.8, 2.1, and a complete Full Set option for productions that need a full range of exposure control. Designed for consistency from strength to strength, the Kondor Blue FullSpec ND Filter is a dependable matte box filter solution for professional video, cinema, commercial, documentary, and run-and-gun production workflows.
