Hot Mirror Clip-In Filters for Sigma FP/BF (L-Mount)

Our Kolari UV/IR Clip-in Filters for Sigma FP/BF L-Mount are designed to block ultraviolet and infrared light while allowing only visible wavelengths (400–700nm) to pass through. This makes it essential for photographers using full-spectrum cameras who want to shoot in normal visible light. By cutting out these unwanted wavelengths, the Hot Mirror Filter restores natural color accuracy, improves sharpness, and delivers true-to-life results.

Engineered with the professional-grade optics that Kolari is known for, these filters are securely housed in a CNC-machined aluminum magnetic frame designed to maximize lens compatibility. This universal solution fits perfectly with lenses lacking filter threads and can be paired with external lens filters for added filtration effects.

Magnetic Mounting System – Quick and secure installation inside the camera body for effortless filter changes.

Professional-Grade Optics – Precision-crafted glass ensures minimal color shifts and maintains sharp, high-resolution imagery.
