Perspective control, tilt-shift lens affords /- 12mm of shift and /- 10° of tilt, and both types of movements can be applied independently, and parallel or perpendicular to one another. Additionally, the tilt and shift functions can be rotated /- 90° in any direction for applying the movements in distinct directions. Tilt-locking mechanism and a large tilt knob benefit operation and ensure the lens stays in place while shooting. One ultra-low dispersion element helps to reduce color fringing and chromatic aberrations for improved clarity and color accuracy. One aspherical element minimizes spherical aberrations and distortion for improved sharpness. An Air Sphere Coating has been applied to lens elements to minimize surface and internal reflections for a marked reduction in lens flare and ghosting when working in strong lighting conditions. A minimum focusing distance of 1.3′ along with a maximum magnification of 0.5x benefits working with close-up subjects. Rounded nine-blade diaphragm contributes to a pleasing out of focus quality that benefits the use of shallow depth of field techniques.
