The Nikkor AF-S DX Zoom 12-24mm f/4.0 lens is a must-have lens to cover the super wide-angle category. When using this lens with your DSLR, it becomes an 18-36mm lens due to the smaller sensor size in most of Nikon’s or Fuji’s cameras (the exception is the Nikon D3). It has 2 Extra-low distortion (ED) glass elements for superior sharpness and color correction, Nikon’s silent wave motor auto focus operation and Internal Focusing (IF) design for smoother and faster operation.
