The PolarPro 4x5.65 Nano ND32 (5-Stop) filter is a rectangular 4x5.65 neutral density filter. It is sized for a matte box tray rather than threading onto the lens. The filter reduces incoming light by 5 stops, enough to shoot wide open in full sun. Additionally, the 4x5.65 Nano ND32 (5-Stop) features a 16-layer multicoating that minimizes internal ghosting and reflections.
Key Features
Neutral Density Filter
A neutral density filter cuts the light reaching the sensor without shifting color, so exposure can be set by aperture and shutter rather than by light level.
Rectangular Tray Format
The filter slides into a matte box tray rather than threading onto a lens, so one filter serves every lens in a set regardless of front diameter.
4x5.65 Tray Size
The filter is cut to 4x5.65 and fits a matte box tray of that size. Tray sizes are not interchangeable, so a 4x5.65 filter will not seat in a 4x4 stage.
5-Stop (ND32) Neutral Density
The filter reduces incoming light by 5 stops, enough to shoot wide open in full sun.
16-Layer Multi-Coating
The glass carries a 16-layer multicoating that minimizes internal ghosting and reflections.
