The Nour Triplet V 2.0/64 Bokeh Control Art Lens from Lomography is a unique lens designed for spherical aberration control on Sony E full-frame mirrorless cameras. Sharpen your subject's appearance beyond focus using the control knob to precisely switch between three different effects. Manipulate light using the included six special drop-in aperture plates in tandem with an aperture range of f/2.0 to f/16. Inspired by Ibn al-Haytham and the Cooke Triplet lens, this lens uses three groups of five optical elements to achieve its dramatic output.
