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.

Rear is 37mm threaded

Front is 52mm threaded to attach 52mm filters

Measures 1.44 inches (3.66cm) from the front edge of the hood to the surface of optic

Internal grooves trap stray light to help minimize lens flare

Compatible with all Lensbaby lenses and optics except the Fisheye Optic

Specially designed to work with the Lensbaby ComposerÆs focus ring and recessed optics û third party step-up rings are too wide to fit into the Composer
