Marumi ND64 (1.8)
The Marumi 100 x 100 ND64 (1.8) is a solid Neutral Density model attachable to M100 Filter System in a moment via strong magnetic force.
- Certified German Quality Glass, B270i with high optical performance
- Neutral density filter with a 64x filter factor that provides a 6-stop exposure reduction, equivalent to 1.8-optical density.
- Dust and dirt adhered on the surface can be quickly and easily blown off.
- Water-/Oil repellent coating shed water off simply also by the air blower. Nuisances such as sweats, skin crème, lotion, fingerprint, or compounded grease stains will be wiped off.

What do we use a square filter instead of a round screw-in filter for?
When and on which occasion do we need to use Marumi square filter?
Marumi innovative M100 Magnetic Filter System allows you to;
- combine a large variety of GND/ND and Circular Polarizer to enable an overwhelming contrast-driven expressiveness
- shoot with no vignetting even with 16mm wide lens due to the ultra-thin frame structure overlaying ND/GND and Circular Polarizer.
- adjust position of graduation up and down, observing the composition through the optical or electronic viewfinder
- one second-attach/detach filters by magnetic force with no time consuming compared to screw-in filters into thread
- bracket a series of GND/ND and almost all of your lens line-up for DSLRs and Mirrorless at hands.
- keep all-in-one set in a pouch exclusive for M100 (optional) easy carrying
