The PC-E Micro-NIKKOR 45mm f/2.8D ED from Nikon is a unique lens allowing you to control focus and perspective. Up to +/- 8.5° of tilt is possible, for focus control; +/- 11.5mm of shift, to adjust perspective and composition; and +/- 90° of rotation is also possible for adjusting the axis of these movements. Close Range Correction also helps to ensure consistent image quality throughout the focusing range. Perspective control, tilt-shift lens affords +/- 11.5mm of shift and +/- 8.5° of tilt, and both types of movements can be applied independently of one another. Additionally, 90° rotation is possible left and right, with stops at 30° intervals. Nano Crystal and Super Integrated Coatings have been applied to lens elements to minimize surface and internal reflections for a marked reduction in lens flare and ghosting.
