What is a neutral density filter?
Neutral density filters, or ND filters, are evenly darkened across the entire filter surface. Depending on the density level, there are lighter and darker neutral density filters. They reduce the amount of light that passes through the lens onto the sensor without changing colors or contrasts in the image.

What is a neutral density filter used for?
Filters are indispensable for long exposures during the day and open up countless creative possibilities. Without using the SIRUI neutral density filter, a significantly overexposed image would result here.

• Soft smearing or flowing effects of moving water or passing clouds.
• Busy squares with many people or heavily trafficked streets can be made deserted through long exposures with a neutral density filter.
• For working with an open aperture to create a shallow depth of field. Large light incidence is compensated by the filter. It simply "swallows" a large part of the light, so you don't have to compensate via camera settings (such as aperture, shutter speed, or ISO value).

Material and workmanship
The high quality of SIRUI filters starts with the material: they are made from Schott glass manufactured in Germany. The glass is fire-polished, ensuring a perfect optical surface. This process also makes the glass extremely robust and durable. Rounded corners and polished edges make the filter glass more break-resistant. This also makes it easier to insert the filter into the holder. The precise workmanship meets the highest standards. The most accurate measuring methods and strict quality control ensure consistent high-end quality of our filters.

2mm thick German Schott glass made in Germany
• extremely light-transmissive
• distortion-free imaging across the entire filter surface
• high solarization stability (no change in properties even under sunlight)
• high chemical resistance
• fire-polished for a perfect optical surface
• extremely robust and durable

Coating and protection
Ultra slim multi-layer nano coating on both sides
• maximum light transmission
• linear and full-surface reduction of reflections (anti-reflective)
• precise color reproduction and color fidelity

Exclusive neutral density film coating on both sides
