KF Juego de filtros Black Diffusion 72mm 2 en 1 (1/4 y 1/8) con cristal óptico AGC japonés, marco de aluminio ultrafino, recubrimiento nano multicapa

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.
