Nikkor AF-S DX 18-140mm f/3.5-5.6G ED VR is a compact and versatile type G AF-S DX lens with built-in CPU and F mount zoom lens. With a 7.8x zoom and up to f/3.5-5.6 Maximum Aperture thats perfectly suited to a huge variety of subjects. It boasts of a construction of 17 elements in 12 groups (including 1 ED lens element, 1 aspherical lens element) that is compact and lightweight. Having 52 mm (P = 0.75 mm) Filter-attachment size, this lens makes a great company in all-around photo shoot. The Vibration Reduction system minimizes the effects of camera shake for blur-free images and helps ensure a steady viewfinder image. Incorporated with Nikons Silent Wave Motor, it enables fast and quiet autofocus. You can get a beautiful soft focus effect from its 7 rounded diaphragm and can even make use of the versatile DX-format 7.8x zoom lens with 18140mm focal range (35mm and Nikon FX-format equivalent: 27210mm). Product Features in Detail SWM (Silent Wave Motor) Nikon's AF-S technology is yet another reason professional photographers like NIKKOR telephoto lenses. AF-S NIKKOR lenses feature Nikons SWM which converts traveling waves into rotational energy to focus the optics. This enables high-speed autofocusing thats extremely accurate and super quiet. Ultra-compact and lightweight An ideal walk-around lens, the body weighs just 195 g. The lens is a mere 59.5 mm long when retracted, and just 76 mm when extended and in use. Aspherical lens elements Aspherical lenses virtually eliminate the problem of coma and other types of lens aberration even when used at the widest aperture. They are particularly useful in correcting the distortion in wideangle lenses. In addition, use of aspherical lenses contributes to a lighter and smaller lens design. Rounded Diaphragm Soft-focus shots of point light sources create regular polygonal shapes that reflect the shape of the opening created by the diaphragm blades. A rounded diaphragm uses blades designed to create a circular opening for a more beautiful soft-focus effect. G-type NIKKOR The G-type NIKKOR has no aperture ring; aperture should be selected from camera body. Versatile DX-format 7.8x zoom lens With 18140mm focal range (35mm and Nikon FX-format equivalent: 27210mm). Wide to telephoto zoom range An ideal walkabout lens, perfect for capturing everything from sweeping landscapes to detailed shots of distant subjects. High optical performance One ED (extra-low dispersion) glass element and one aspherical lens element ensure high resolution and contrast while minimizing most forms of aberration and colour dispersion. Vibration Reduction (VR) system Minimizes the effects of camera shake and lets you shoot at shutter speeds that are up to four stops slower. VR operation is quiet, even when filming. A-M switch An element that locks the focus ring during autofocus while enabling behavior similar to a manual focus lens in manual focus mode with sufficient load when the focusing ring is rotated. The focus rings on the AF-S DX NIKKOR 18-55 mm f/3.5-5.6G VR, AF-S DX Zoom Nikkor ED 18-55 mm f/3.5-5.6G, and AF-S DX Zoom-Nikkor ED 18-55 mm f/3.5-5.6GII rotate during autofocus. Internal Focusing (IF) This allows for a more compact, lightweight construction as well as a closer focusing distance. In addition, a smaller and lighter focusing lens group is employed to ensure faster focusing. A/M mode (autofocus with manual override, AF priority mode) An autofocus-priority autofocus mode that reduces the sensitivity of the manual override to prevent unexpected switching from auto to manual.
