With an aperture range from f/2.5 to f/22, the Soft Focus II optic from Lensbaby is a new-and-improved version of one of the earliest and, recently, most sought-after optics in Lensbaby’s Optic Swap System, the original Soft Focus optic. Compatible with all of Lensbaby’s current and legacy Optic Swap lens bodies, the Soft Focus II improves on its predecessor by adding a 12-blade manually adjustable internal aperture to its unique and versatile drop-in magnetic aperture system.
