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 it'sunique and versatile drop-in magnetic aperture system.Less ThanbRGreater ThanLess ThanbRGreater ThanWhen shot at its brightest aperture settings, the Soft Focus II creates an impressionistic image with subtle sharp detail beneath. Rendering a color palette tending toward soft pastels at brighter apertures and producing a remarkably flat field of focus, this optic makes possible images that are impossible to achieve with any other lens. Stopped down to f/8 or darker, the Soft Focus II produces beautifully detailed, traditionally sharp images with a large central area of focus and out of focus edges on full frame sensors and 35mm film. Quick variability of the optical effect from impressionistic and full of glow to contrasty and sharp is made possible by the internal 12-blade aperture that is adjusted by turning the front of the optic.
