Sirui 100 x 150mm Reverse Graduated Neutral Density Filter — 4-Stop Rectangular

Ideal for sunrise and sunset scenes, this Sirui reverse graduated neutral density filter places a concentrated dark band at the horizon to control bright skies while leaving foregrounds less affected, producing more balanced exposures across the frame. It provides a 4-stop reduction with a reverse gradient specifically suited to scenes where the brightest area is near the horizon. The rectangular 100 x 150mm size is made to slide into standard filter holders for simple integration with your current setup. The optical panel is 2mm thick and built from high-quality materials to offer strong scratch resistance, protect your lens, and withstand regular use in the field. Manufactured for accurate light transmission, the filter reduces exposure without introducing unwanted color casts, preserving true-to-life color fidelity so your images retain natural tones.
