The Heliopan 37mm KB-15 (80A) Filter is a precision color conversion filter designed to shift the color temperature from tungsten-standard 3200K to daylight-standard 5500K. This conversion enables the use of daylight-balanced film or sensors under tungsten lighting conditions without introducing unwanted color casts. The filter has a 4x filter factor, necessitating a 2-stop exposure compensation for accurate exposure. Constructed with a 37mm brass mounting ring finished in matte black, the filter minimizes internal reflections and flare. It utilizes SH-PMC (Super High-Performance Multi-Coated) Schott optical glass, which delivers enhanced contrast and significantly reduced surface reflection compared to uncoated filters. This results in improved image clarity and color fidelity essential for professional photography and cinematography applications requiring precise color management.
