BREAKTHROUGH X4 ND FILTERS

WEBSITE: www.breakthroughfilters.co.uk PRICE: From £109 / $139

These rugged neutral-density filters can withstand harsh conditions. Breakthrough guarantees each X4 ND against defects for 25 years, enabling landscape pros to shoot in extreme wind, salt water and other abrasive elements without worry. In 3, 6 or 10-stop versions (and sizes from 43mm to 95mm), each filter is crafted from a SCHOTT Ultra White B 270 optical glass that produces no obvious colour casts. A full traction texture around the filter circumference makes taking them on and off a cinch.
