The Lensbaby Step-up/Shade gives you more artistic control. Standard step-up rings will not work with the Lensbaby Composer, so we created a special 37mm to 52mm step-up ring that fits into the Composer and provides lens shade capability. With the Step-up/Shade you can add 52mm filters to your favorite combination of Lensbaby optic, aperture, and accessory lens, opening up even more creative possibilities.
