Features:

• The first fisheye lens developed exclusively for use with Nikon DX Format*
• Ultra wide picture angle of 180° 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
• DX Nikkor is designed exclusively for use with Nikon Digital SLR models D1, D1X, D1H, D2H, D100 and D70.
