The Lensbaby Step-Up/Shade is a combination 37mm to 52mm step-up ring/lens shade that provides good light and flare blockage as well as a convenient way to use 52mm filters on Lensbaby lenses. Standard step-up rings do not provide the added benefit of the lens shade functionality, nor will they work on a Composer as they are too wide to fit into the Composer, preventing the focus ring from rotating fully.
Rear is 37mm threaded to attach to all Lensbaby lenses and optics except the Lensbaby Fisheye Optic
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, providing significant protection from flare
Internal grooves trap stray light to help minimize lens flare
Compatible with all Lensbaby lenses and optics except the Lensbaby Fisheye Optic
Specially designed to work with the Lensbaby Composer’s focus ring and recessed optics – third party step-up rings are too wide to fit into the Composer, preventing the focus ring from rotating fully
