The Hoya 67mm ProND-100000 Neutral Density 5.0 Solar Filter provides a 16.6-stop exposure reduction, and its 5.0 density creates a darkening of the entire image with a 0.001% transmittance that is effective for solar and solar eclipse photography. 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.
SAFETY FIRST: Observing the Sun without the proper protection may result in serious personal injury, including permanent eye damage and blindness, and/or damage to equipment. Never point an optic at the sun without an approved solar filter on the front of the optic. For direct solar viewing, viewing the sun through an optic, or when using cameras with an optical viewfinder, ensure your filter is ISO 12312-2 (also written as ISO 12312-2:2015) certified. Never use photographic neutral density filters for direct solar viewing, viewing the sun through an optic, or when using cameras with an optical viewfinder.
