Nisi Explorer Nano IR Medium Graduated ND 0.9 100x150mm camera filter

Explorer Nano IR Medium Graduated ND 0.9

This rectangular filter measures 100x150mm and fits standard 100mm holder systems. It provides a three-stop density reduction of 0.9 to darken bright skies while leaving the foreground unaffected. The medium graduation transitions from dense to clear across the frame, suiting scenes with buildings or small mountains that reach into the skyline. It is built for photographers who work in demanding outdoor conditions.

Double Strength Glass Construction

A specialised hardening process makes the B270 glass twice as resistant to breakage as typical filter glass. This durability lets the filter survive knocks and drops that would shatter a standard plate during active use. The strengthened substrate maintains optical quality while handling the stresses of frequent insertion and removal from a holder. Photographers who hike, climb or shoot in rough terrain gain a reliable tool that stays intact.

IR Layers and Nano Coating

Integrated IR layers suppress infrared contamination to keep colours accurate across the exposure. A low-reflection nano coating cuts flare and ghosting when shooting toward bright light sources. The coating also repels water and oil, making the surface easier to clean in the field. Together these layers preserve contrast and colour fidelity without adding colour cast.
