Spanning a long, versatile zoom range, the AF-S NIKKOR 200-500mm f/5.6E ED VR Lens from Nikon is a telephoto zoom characterized by a constant f/5.6 maximum aperture for consistent performance throughout the zoom range. The optical design incorporates three extra-low dispersion glass elements to reduce chromatic aberrations and distortions for increased sharpness and color accuracy. Also contributing to improved image quality, a Super Integrated Coating has been applied to lens elements to lessen flare and ghosting for improved contrast and clarity. A Silent Wave Motor AF system produces fast, near-silent focusing performance that suits both stills shooting and movie recording, which can instantly be manually overridden by simply turning the manual focus ring. Further contributing to photographing in fast-paced situations and difficult lighting, VR (Vibration Reduction) image stabilization compensates for the effects of camera shake by up to 4.5 shutter speed stops. Additionally, an electromagnetic aperture mechanism is integrated into the lens design to provide greater exposure control stability that is especially beneficial when working with faster continuous shooting rates.
Contrary to popular belief, a super telephoto does not have to be a massive lens, proven here with the Nikon AF-S NIKKOR 500mm f/5.6E PF ED VR. Taking exceptionally long reach and giving it a hand-holdable form factor, this 500mm prime utilizes a unique Phase Fresnel element to greatly reduce the size and weight compared to previous versions of the focal length. This PF element, along with three extra-low dispersion elements, also helps to virtually eliminate color fringing and chromatic aberrations in order to achieve a high degree of clarity, sharpness, and color fidelity. Complementing this advanced optical design, individual elements also feature both Nano Crystal and Super Integrated Coatings to suppress flare and ghosting, as well as a protective fluorine coating to guard the optical system from dust and moisture.
The 40 mm f/2.8G AF-S DX Micro-Nikkor Lens from Nikon is a superb carry-it-everywhere, jack-of-all-trades lens for your Nikon DX camera. The focal length (equivalent to 60 mm in FX or 35 mm format) gives it the versatility to capture portraits, street shots and landscape photos without breaking a sweat. And the light weight (9.9 oz/280 g) means you`ll actually carry it around with you, greatly increasing the chance that you`ll get a great photo.
