The world seen anew with SIRUI grey filters

What is the SIRUI SOFT graduated filter?
The SIRUI soft graduated grey filters have a soft grey gradient from the filter edge to the filter centre. This means the grey part of the filter darkens the image. The high quality SIRUI square filters are made of German Schott glass B270® and come in a padded pouch.

Why do you need a soft graduated filter?
A soft graduated filter is perfect for subjects such as landscapes or skylines where the horizon is not clearly defined (e.g. as a result of trees, mountains or houses). The result is impressive images with detailed clouds in the sky and a properly exposed foreground.

The filters can be combined in the filter holder, resulting in astounding long exposures and breath-taking landscape shots.

Materials and manufacture
The high quality of SIRUI filters begins with the material: they are manufactured from German Schott glass. The glass is fire-polished, ensuring a perfect optical surface. This process also makes the glass extremely robust and resilient. Rounded corners and polished edges make the glass shatter-proof. This also makes it easier to insert the filter into the holder. The precise manufacturing meets the highest standards. Accurate measurement procedures and strict quality control ensure consistent quality of the filters.
