Nikon 35mm Lenses 17 f/2.8D ED-IF AF-S Zoom Digital SLR Cameras
Aspherical lens elements
Nikon has introduced the first photographic lens with aspherical lens 1968. What differentiates them? Aspherical lenses virtually eliminate the problem of coma and other types of lens aberration - even when used at maximum aperture. They are particularly useful for correcting the distortion in wide angle lenses. Furthermore, the use of aspherical lenses contributes to a lens smaller and lighter. Aspherical lenses are precision ground the most beautiful expression of Lens-craft, strict production standards are extremely high. Hybrid lenses are made of a special plastic molded glass optics. Aspherical glass lenses are manufactured by cast molding a unique type of optical glass with a special metal die technique.
Internal focusing
Imagine being able to focus a lens without changing its size. Nikon If technology allows just that. All internal optical movement is limited within the non-extension lens barrel. This allows a more compact, lightweight construction and a distance of focus closer. Addition, a smaller and lighter focusing lens is used to ensure a more rapid development. If the system is also in most Nikkor telephoto and selected Nikkor zoom.
A distance information
Type D and G-type Nikkor lenses relay subject to the information from the remote camera to AF Nikon camera bodies. This then makes possible advances like 3D Matrix Metering and 3D Multi-Sensor Balanced Fill-Flash. Note: Type D and G-type Nikkor lenses provide distance information for the following cameras: Auto exposure, F6, F5, F100, F90X, F80, F75, F70, F65, F60, F55, F50, Pronea S Pronea 600th , D2 series, D1 series, D100 and D70s/D70. Flash control, F6, F5, F100, F90X, F80, F75, F70, D2 series, D1 series, D100 and D70s/D70.
Silent Wave Motor
Nikon AF-S technology is yet another reason professional photographers like Nikkor telephoto lenses. AF-S Nikkor Nikon SWM function which converts "traveling waves" into rotational energy to focus on the optics. This enables automatic focusing at high speed, which is extremely accurate and super quiet.
