Cokin Z-Pro Nuances Extreme Centre Graduated ND4 2 Stop

The Cokin Z-Pro Series Nuances Glass Centre Graduated ND4 filter balances exposure at the centre of an image, reducing exposure by 2 stops at the densest part. Made from Schott B270 mineral glass, renowned for its high light transmittance, its internal and external reflections are minimised by Cokin’s new nano metallic alloy coating process. The transition between ND and clear areas is soft, and it's useful in taming excess light just at the horizon point. 101 x 143 x 2.3mm, for Cokin Z-Pro (L Series), Lee, Hitech or other compatible filter holders.
