Designed for use with the Marumi Magnetic Filter Holder M100, these ND filters are available in nine densities. The Marumi Magnetic Filter System is far more slender and compact than a traditional slot-in system, requires less set-up time and makes it easier to swap filters quickly and neatly.
The strong magnets grab the filter with one touch, holding it tightly and securely, effectively eliminating issues caused by light leaking when using traditional slot-in style square filters. One M100 can hold up to 3 stacked filters, allowing you to layer up for different effects. The 100mm square glass is contained within a sturdy metal frame with knurled edges and a wide tab at the top, allowing for ease of grip without adding fingerprints to the filter.
Available in ND4, ND8, ND16, ND32, ND64, the density number refers to the darkest part of the glass.
The Marumi Magnetic Filter System means no more need to buy separate filters for each lens size – simply attach the aluminium Magnetic Filter Holder to the front of your lens, and swap all your filters on and off with ease.
These quality Japanese-made optics have state-of-the-art coatings for anti-static, anti-scratch, low reflection and to repel water & oil. They maintain a neutral colour and suppress any infrared light casting.
