The first fisheye lens developed exclusively for use with Nikon DX Format*. Ultra wide picture angle of 180 degrees on DX sensor achieved by producing a smaller image circle (the size of the image that is projected by the lens on to the sensor) enabling smaller lens diameter, lighter weight and optimal image quality from center-to edge-to-corner on the image. Equivalent to 16mm focal length on 35mm. Minimum focus distance of 0.14m (5.5 in.), or 0.03m (1.2 in.) from the lens front, makes extreme close-ups possible. Close-Range Correction (CRC) provides high performance for sharper images when taking pictures up close. Extra-Low Dispersion (ED) glass element minimizes chromatic aberration; design enables a combination of wider angle-of-view with optical characteristics that are optimized for Nikon digital SLR camera sensors. Nikon D-type design provides precise distance information for flash and ambient light exposure processes, rounded diaphragm to make out-of-focus elements appear more natural, G Type DX Nikkor is designed exclusively for use with Nikon Digital SLR models . Built-in Flower Type lens Hood, Fully Compatible with D1, D1X, D1H, D2H, D100, and D70
