SIRUI RGND8 (0.9) Rectangular Gray Gradient Filter Reverse 100x150mm (3 Stops)

SIRUI RGND8 (0.9) Rectangular Graduated Neutral Density Filter Reverse 100x150mm (3 Stops)

Impressive shots with harmonious exposure throughout the entire image

A reversed (Reverse) graduated filter is perfect for subjects with a bright center and a clearly defined horizon (e.g., sunsets or sunrises). The result is impressive shots with correctly exposed bright and dark areas.

What are SIRUI Graduated Neutral Density REVERSE filters?
SIRUI Reverse graduated neutral density filters feature a hard gradient towards the center and a soft gradient towards the upper filter edge. Depending on the density level, the filter gradients are lighter and darker. This gradient darkens the tinted part of the filter over the subject. The high-quality SIRUI rectangular filters are made from German Schott glass B270® and come in a padded pouch for optimal protection.

SIRUI rectangular filters can be ideally combined to achieve the desired effect.

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 of SIRUI filters meets the highest standards. The most accurate measuring methods and strict quality control ensure consistent high-end quality of our filters.
