This Lensbaby Pinhole/Zone Plate Optic is part of the Lensbaby Optic Swap System. Lensbaby has developed a line of different "optics" that can be interchanged with the Muse, Composer, and Control Freak lenses. This provides artists with an almost unlimited variety of looks and styles to capture their unique visions.
The Pinhole/Zone Plate Optic lets you shift easily back and forth from the pinhole mode to the zone plate mode by simply sliding a toggle inside the optic. In either pinhole or zone plate mode, this optic insert achieves softer focus, dreamy images that are equally sharp from edge to edge.
