This Master 150mm Filter Holder Kit from Benro is designed to allow for the use of up to two 150mm-wide, 2mm-thick filters, along with an included circular polarizer filter, on a wide-angle lens with 95mm or 77mm front filter threads without vignetting. Besides the circular polarizer, this kit contains two additional filters that can be used individually or in various combinations to improve the results of your photography. Those filters consist of a 150 x 150mm solid neutral density 4-stop filter, as well as a 150 x 170mm graduated neutral density 3-stop filter.
Along with this kit's Master 150mm Filter Holder, 95mm filter holder adapter ring, 77-95mm step-up ring, three filters, and two filter wrenches, a light tent is provided along with a padded pouch. If a jammed or over-tightened screw-on filter requires removal from a lens before using this kit's adapter ring or step-up ring to mount the filter holder, the squeeze-type filter wrenches can help to enhance grip and leverage around a filter ring. Together, the wrenches are compatible with filters ranging from 46 to 72mm and 67 to 82mm in diameter.
By covering the sides of the filter holder during use, the light tent can be used to eliminate stray light, which could have unwanted effects on exposure, from coming in-between any installed filters and the filter holder and lens behind it. For storage and transport, the pouch accommodates the entire filter holder kit.
