The Nikon PC-E NIKKOR 24mm f/3.5D ED Tilt-Shift Lens is an ultra-wide lens with special "Perspective Control" tilt and shift functions, making it ideal for architectural and nature photography. Using tilt and shift correction will help obtain a natural-looking perspective by eliminating distortion such as keystoning that can appear in architectural images. It features ±8.5° of tilt along with ±11.5mm of shift, and each can be used either by itself or in combination with the other. The mount can also rotate 90° left and right for setting which axis to have the shift and tilt set to.
