Our 4"x5.65" +1/4 Diopter Brilliant tray mount close-up lenses have a large 5.1" diameter clear aperture in the tray, allowing use with large lenses and wide angle lenses. Engineers designed this system to provide quick access to available close-up lenses at all times because of the ease of changing between two shots, one for a small subject and another for a larger subject. The translucent glass adds visual depth to shots and brings out rich colors from the background.
