Cokin WA1T669 A669 Graduated Filter

The Cokin A669 Graduated Filter is a rectangular, hard-edge graduated neutral density filter designed for the Cokin A series filter system. Its primary purpose is to darken a portion of the frame — typically the sky — while leaving the rest of the image unaffected, allowing photographers to capture balanced exposures in high-contrast landscape scenes without relying on post-processing. The 2 2/3-stop density gradient is darkest at the edge and transitions sharply to clear at the midpoint, giving you a defined line of separation that works best with straight, unobstructed horizons like seascapes, prairies, and desert landscapes.

Constructed from CR-39 organic glass, a material originally developed for the vision lens industry, the A669 is notably lightweight and resistant to impacts, making it well-suited for outdoor use where filters are frequently handled and swapped. CR-39 also provides excellent optical transmission and high compatibility with coloring processes, ensuring minimal impact on image sharpness and color fidelity. The rectangular form factor allows you to slide the filter up or down within the Cokin holder to position the graduated transition precisely where your composition demands, offering a degree of creative control that circular screw-on graduated filters cannot match.
