KF 72mm Black Diffusion Filter Set 2-in-1 (1/4 and 1/8) with Japanese AGC Optical Glass, Ultra-Slim Aluminum Frame, Multi-Layer Nano-Coating

Capture cinematic softness with two strengths in one kit: a 1/4 and a 1/8 Black Diffusion filter, both crafted from Japanese AGC optical glass with multi-layer nano-coating. The 72mm thread fits a wide range of lenses, and the ultra-slim 3.3mm aluminum frame prevents vignetting even on wide-angle glass.

Overview

This K&F Concept 2-in-1 filter set includes two Black Diffusion filters — 1/4 and 1/8 strength — designed to soften skin tones, reduce blemishes and wrinkles, and lower contrast for a dreamy, film-like glow. Ideal for portrait, wedding, and cinematic video work, these filters help you achieve a polished look straight out of camera.
