Syrp 82mm Super Dark Variable Neutral Density Filter Kit with 77mm and 72mm stepdown. Super Dark Variable Neutral Density Filter Kit from Syrp includes a solid variable neutral density filter that can be directly attached to a lens with 82mm front filter threads and provides an exposure reduction of 5 to 10 stops. The 1.5 to 3.0 density creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed than normally required. The degree of density is easily controlled by rotating the front filter ring, helping you to predetermine the additional exposure length required. By slowing your exposure time or increasing your aperture, you are able to control depth of field and convey movement more easily. - Lightweight and durable aluminum-alloy filter rings with 82mm front filter threads allow for use with other filters - Side knurlings to provide a more textured grip when mounting onto or removing from a lens - Index numbers indicate different exposure-reduction values - Aluminum-alloy step-up rings that allow the filter to be used on lenses with 77mm or 72mm front filter threads - 5.0 x 5.0" microfiber cleaning cloth for filter maintenance - Zippered, leather case for storage and transport of filter, one attached step-up ring, and microfiber cleaning cloth
