Aurora-Aperture PowerND IR Filter Kit for Select Irix EF Wide-Angle Lenses

Use ND filters with your wide-angle lenses with the PowerND IR Filter Kit for Select Irix EF Lenses from Aurora-Aperture. This kit includes four solid ND filters that range from 3 to 16 stops of light reduction, and a IR rear-mount filter holder.

This kit is tailored as a solution for using glass filters on wide-angle Irix EF lenses without needing an excessively large front-mount filter or sacrificing image quality by using a gel filter. The IR format allows for a glass filter to be mounted behind the rear element, which makes the filters small and easy to carry. Made of metal for durability, the adapter replaces the original plastic gel filter holder that comes with the lens.

The four solid neutral density filters included in this package darken the entire image and allow for the use of slower shutter speeds and wider apertures. Made of durable Gorilla glass, the filters are rated to reduce light by 3, 6, 12 and 16 stops. Their combined potential widens the range of shutter speeds available to the photographer, from exposures of a few seconds under dusk to several minutes during bright daylight. Several layers of nano coating are applied to the filters in order to preserve image quality and repel water, oil, and dust.
