Their versatility makes these the perfect lens complement for a myriad of applications, including photographing architecture, nature, interiors and still-life especially product photography. When shooting subjects, such as tall buildings with a conventional lens, composition often calls for tilting the axis of a camera. This typically results in a significant distortion of converging lines, impacting the desired visual accuracy of the image. A PC-E NIKKOR lens' "shift" control provides correction for this type of distortion. "Shift" control can also give a photographer the ability to "effectively" move the apparent position of the camera providing further perspective versatility, allowing, for example, the ability to avoid unwanted reflections in an image. A PC-E lens' "tilt" control gives photographers additional creative control over depth-of-field. Known as the Scheimpflug principal,tilt-shift lenses are capable of modifying the focal plane of the lens, allowing the extension or limitation of the point of critical sharpness in the image. The combination of "tilt" and "shift" co</br></br>Amazon.com</br></br>Perfect for portrait, nature, and commercial photography, the Nikon medium-telephoto 85mm, f/2.8D lens lets you control the perspective more than with other lenses, with the ability to tilt, shift, and rotate while you shoot. The lens offers a wide shifting range--plus or minus 11.5mm--with a tilting range of plus or minus 8.5 degrees to provide exceptional perspective control. In addition, the lens revolves plus or minus 90 degrees in 30-degree increments, providing versatile tilt/shift shooting effects. As a result, you can enjoy all kinds of distorted perspectives and unique angles, giving your shots extra life.  <p> The lens is coated with Nikon's Nano Crystal Coat, which virtually eliminates internal reflections across a wide range of wavelengths to produce even greater image clarity. The high-performance Nikon Super Integrated Coating (SIC), meanwhile, offers superior color performance and substantially reduced ghosting and flare. Other details include an auto-aperture control with an electromagnetic diaphragm (requires Nikon D3, D700, or D300 D-SLR camera), and a rounded nine-blade diaphragm that produces a more natural appearance for out-of-focus image elements.  <p> <b>Technical Specifications</b><br> <ul> <li>Focal length: 85mm</li> <li>Maximum aperture: f/2.8</li> <li>Minimum aperture: f/32</li> <li>Autofocus: No</li> <li>AF-S (Silent Wave Motor): No</li> <li>Compatible formats: FX, DX, FX in DX crop mode, 35mm film</li> <li>Distance information: Yes</li> <li>ED glass elements: No</li> <li>Super Integrated Coating (SIC): Yes</li> <li>Nano Crystal Coat: Yes</li> <li>Minimum focus distance: 1.3 feet</li> <li>Angle of view: 28 degrees @ 30 feet</li> <li>Lens (elements): 6</li> <li>Lens (groups): 5</li> <li>Maximum reproduction ratio: 1:2</li> <li>Mount type: Nikon F-Bayonet</li> <li>Filter type: Screw on</li> <li>Filter size: 77mm</li> <li>Lens attachment size: 77mm</li> <li>Lens case: CL-1120 flexible lens pouch</li> <li>Lens hood: HB-22 bayonet hood</li> <li>Dimensions: 3.3-inch diameter, 4.2 inches long</li> <li>Weight: 22.4 ounces</li> <li>Supplied accessories: HB-22 bayonet hood, CL-1120 flexible lens pouch, LF-1 rear lens cap, LC-77 snap-on front lens cap</li> </ul></br><br/>http://www.amazon.com/gp/product/B001BTAZHM
