The Hoya ProND-100000 Neutral Density 5.0 Filter provides a 16.5-stop exposure reduction, and its 5.0 density creates a darkening of the entire image with a 0.001% transmittance. With this filter, users can capture photographs with a wider aperture or a slower shutter speed than normally required. The filter material provides an accurate neutral color rendition without any noticeable color-cast to the images, and its vapor-deposition application to the glass lens ensures an even and consistent layer. An aluminum-alloy filter ring holds the filter for durability while remaining lightweight. The filter is not suitable for direct solar viewing with the naked eye, and should only be used for photography purposes.

With more than 16.5 stops of light reduction the filter yields exposure times of several minutes in bright sunlight. Hoya uses a precise metal vapor deposition process to create the ultra-dark ND effect while maintaining a very neutral color balance for faithful color reproduction at extremely long exposure times.

Caution, Please Read: The Hoya PRO ND100000 is not suitable eye protection for viewing of sun. Do not look directly or indirectly into the sun without appropriate eye protection. The ND100000 should be installed in front of the camera lens or telescope before trying to align it with the sun. Do not use an optical viewfinder when aligning your camera or telescope with the sun. If the camera has an LCD screen with a live-view feature, use that to align it with the sun and for viewing.

It is possible to damage your camera's sensor if the sensor is exposed to direct sunlight for extended periods of time. Please take extreme caution when photographing the sun.
