Tokyo Grapher CDF-L Mist Filter 67mm The CDF (Cinematic Diffusion Filter) is a camera lens filter that allows you to take high-quality photos and videos with a cinematic atmosphere by creating a matte, analog-like texture and impressive light effects. The L and S versions differ in their light diffusion strength, with the L version expressing light more strongly and impressively. It is easy to use in any scene for both photos and videos, and it can be used as a regular protective filter because it is water-repellent and oil-repellent for easy maintenance.
