The Lensbaby Macro Converters are compatible with all Lensbaby lens bodies and optics, making macro photography available to all new and existing Lensbaby photographers with multiple options above and beyond the existing Lensbaby Macro kit.
Lensbaby's Macro Converter Extension Rings for Lensbaby lets you take that Lensbaby look as close to your subject as you want--even touching it in some cases--and get a picture that's in focus. You can choose the 8mm ring, the 16mm ring (both included), or combine them for a 24mm ring, so you have plenty of control over exactly how close-up you want your photo to be. The converters simply screw into the Lensbaby lens body - and then the optic screws into the converter.
The converters are compatible with Composer, Composer Pro, Muse, Scout, Control Freak and all optics (the Fisheye Optic is only compatible with the 8mm converter, as it allows you to actually focus on a subject that the lens is touching).
