The Nikon AF-S Nikkor 70-200mm f/2.8G ED VR II Lens is perfect for sports, photojournalism and wildlife photography due to the fast f/2.8 aperture. Vibration Reduction, engineered specifically for each VR NIKKOR lens, enables handheld shooting at up to 4 shutter speeds slower than would otherwise be possible, assuring dramatically sharper images. It has seven Extra-low Dispersion (ED) elements, offering superior sharpness and color correction by effectively minimizing chromatic aberration, even at the widest aperture settings. The Nano Crystal Coat further reduces ghosting and flare for even greater image clarity.
The 70-200 f/2.8G also has Nikon Super Integrated Coating (SIC), whichenhances light transmission and offers superior color consistency and reduced flare. Its exclusive Nikon Silent Wave Motor (SWM)enables fast, accurate, and quiet autofocus. A rounded 9-blade diaphragmrenders more natural appearance of out-of-focus image elements. Its Internal Focus (IF) driveprovides fast and quiet autofocus without changing the length of the lens, retaining subject-working distance through the focus range. Focusingthroughout the entire zoom range up to 4.6 feet provides extended versatility. The M/A focus mode switch enables quick response to changing situations between manual and autofocus operation. Finally, the included Flower-shaped lens hood (HB-48) shades the objective from unwanted, image-degrading light.
This is the magnifying factor of a lens. Macro lenses will often be described by their “magnification factor”. A lens with a 1:1 magnification factor produces a projected image on the sensor which is the same as the subject.
The individual pieces of glass that form the overall optical construction. Most lenses have between four and eleven elements to bend the light rays to ensure a perfectly formed image appears on the light sensitive surface, such as a film or CCD. The elements are arranged in groups and may be seen in specification sheets as, for example, 6 elements in 4 groups. That configuration may have two single elements and the other four grouped in pairs.
