Lensbaby Double Glass II Optic

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 Lensbabys Optic Swap System, the original Double Glass optic. Compatible with all of Lensbabys 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.

Lensbabys Double Glass II optic is compatible with all Optic Swap macro accessories including Lensbabys 46mm Macro Filter Kit and Macro Converters.
When shot at its brightest aperture setting of f/2.5, the Double Glass II creates a tiny sharp spot of focus with increasing blur away from that spot. This optic, combined with the shaped apertures makes possible images that are impossible to achieve with any other lens besides theoriginal Double Glass optic. Stopped down to f/4 or darker, the Double Glass II produces an increasingly large sweet spot of focus to match ones subject matter with the size of the sweet spot desired to portray that subject as the user envisions. Quick variability of the optical effect from impressionistic with mostly blur to a very large sweet spot with just a little bit of blur is made possible by the internal 12-blade aperture which is adjusted by turning the front of the optic.
