NiSi Cine Filter Nano IRND 4x4" 2.1

A NiSi Cine Nano IRND neutral density filter in 4x4" size, density 2.1. It reduces exposure and darkens the entire image, letting you shoot with a wider aperture or slower shutter speed than normally required. By slowing the exposure time or widening the aperture, depth of field and motion can be controlled more easily.

• Design optimized for digital sensors, with nearly flat attenuation of visible and infrared light
• One layer of NiSi Optical Nano Coating on each surface, maintaining color neutrality and suppressing color casts
• Optical glass, scratch resistant, 4 mm thick
• Does not affect the coloration of the image and is ideal for use with other filters
• Included: leatherette pouch for storage and transport
