About Lindsey Optics Brilliant IR ND

For photographers seeking complete creative control in varying lighting conditions, the 4x5.65" Brilliant Full Spectrum IR 2.1 Neutral Density Filter with Anti-Reflection Coating, 7 Stop, 0.78% Transmission is an indispensable tool. This high-quality, durable filter effectively reduces the amount of light entering your lens, enabling you to open the aperture for a reduced depth of field or slow the shutter speed for motion blur.

Offering a broad range of ND values from ND 0.3 to ND 3.0, this versatile filter provides light reduction between 1 stop (50% transmission) and 10 stops (0.1% transmission). This gives you the flexibility to adapt to any lighting situation, from bright daylight to low light conditions.

The innovative design of this Lindsey Optics filter incorporates Full Spectrum Neutral Density technology. This means it attenuates all wavelengths of light, including UV, Visible, and Infra-Red. By cutting Infra-Red energy, it eliminates "Infra-Red pollution," which can cause unwanted color shifts in digital cameras.

Constructed from solid glass, the neutral gray color of this filter is inherent in the glass itself, not in a plastic layer or surface coating. This ensures the color will never fade, providing consistent performance over time.

The filter also features a broadband anti-reflection coating for brilliant contrast. This durable coating effectively reduces reflections on both filter surfaces, minimizing stray light and resulting in images with vibrant contrast and color saturation.

Finally, for improved traceability and inventory control, every Lindsey Optics filter comes with a unique serial number. This is particularly beneficial for dealers and rental houses.

In summary, the 4x5.65" Brilliant Full Spectrum IR 2.1 Neutral Density Filter with Anti-Reflection Coating, 7 Stop, 0.78% Transmission is a high-quality, effective, and versatile tool for photographers seeking to enhance their creative control in any lighting condition.
