Stretch your Lensbaby vision to the max with the 0.42x Super Wide Angle Conversion lens, which converts your Lensbaby lens's focal length from 50mm to 21mm. Specifically designed for compatibility with the Lensbaby Optic Swap System, this 0.42x is lighter and sharper than any comparable product on the market. The 0.42x also has a macro capability, allowing you to focus as close as 2.75" (7 cm) away from the front of your lens.
