Lensbaby Composer Pro II with Double Glass II Optic for Canon EF Mount Camera

This Lensbaby Composer Pro II + Double Glass II for Canon EF mount camera system comes with an aperture range from f/2.5 to f/22, the Double Glass II optic from Lensbaby is a new-and-improved version of one of the earliest and most popular optics in Lensbaby’s Optic Swap System, the original Double Glass optic. Compatible with all of Lensbaby’s current and legacy Optic Swap lens bodies, the Double Glass II improves on its predecessor by adding all-metal construction and a 12-blade manually adjustable internal aperture to its unique and versatile drop-in magnetic aperture system.

Nine specialty drop-in magnetic aperture disks ship with the Double Glass II optic. A five pointed star, a heart and another seven of the nine artistically designed and shaped drop-in apertures, developed by visual artists in the Lensbaby community, modify the out of focus areas of the image to add texture.

When images shot with these uniquely shaped drop-in apertures contain out of focus points of light those points of light are rendered in the shape of the aperture. Lensbaby’s Double Glass II optic is compatible with all Optic Swap macro accessories including Lensbaby’s 46mm Macro Filter Kit and Macro Converters.
