Heliopan's FLD filter transforms fluorescent-lit photography by neutralizing unwanted green casts that plague daylight film and digital sensors. This precision-engineered color corrector shifts light to a natural 5500K daylight temperature, delivering true-to-life colors every time. Crafted from premium German Schott glass with an 8-layer multi-coating, it resists reflections, flare, and environmental damage while maintaining exceptional optical clarity. The robust black anodized brass mount eliminates binding issues and ensures reliable performance. With just a 1-stop exposure adjustment needed, you'll capture accurate, vibrant images under any fluorescent environment—professional results without compromise.

• Color Correction: The primary function is to neutralize the harsh green hue produced by fluorescent bulbs, ensuring more accurate and natural color reproduction in images.
• High-Quality Optics: Heliopan filters are constructed in Germany using high-quality Schott glass, which is ground, polished, and coated to the highest standards to ensure optical clarity and minimize reflections.
• Durable Build: The filter is mounted in a precision-cut black anodized brass ring, which is more resistant to binding or cross-threading than cheaper aluminum mounts and provides additional strength.
• Multi-Coating: Most versions feature a multi-coating (often 8-layer SH-PMC coating) to further reduce reflections, minimize flare, and repel dust and moisture for easier cleaning and maintenance.
• Filter Factor: The filter typically has a factor of 2x, requiring a 1 stop exposure increase to compensate for light loss
