Equivalent to 16mm focal length on a 35mm. Equivalent to 16mm focal length on a 35mm.  Design enables a combination of wider angle of view with optical characteristics that are optimized for Nikon digital SLR camera sensors. Rounded diaphragm makes out-of-focus elements appear more natural. Ultra-wide picture angle of 180 degrees on DX sensor is achieved by producing a smaller image circle (the size of the image that is projected by the lens onto the sensor) enabling a smaller lens diameter, lighter weight and optimal image quality from center-to-edge-to-corner on the image. Minimum focus distance of 0.14m (5.5 in.) or 0.03m (1.2 in.) from the lens front, makes extreme close-ups possible.
