AF-S Zoom-Nikkor 24-85mm f/3.5-4.5G ED-IF lens includes a selection of Nikon advanced technology features, including Extra Low Dispersion Optical Glass (ED), Super Integrated Coating (S-IC), Internal Focusing Construction (IF), Aspheric optic (ASP), Silent Wave Motor Technology (SWM), Distance Technology, and G-Type design (aperture control exclusively from camera body).
Extra Low Dispersion Optical Glass is a high index, low dispersion glass that enables high optical performance from this wide-range compact zoom lens. Through low dispersion characteristics the lens' color performance is enhanced, adding sharpness and contrast to the image.
Super Integrated Coating, a form of multiple layer coating provides pictures of excellent clarity.
Internal Focusing Construction is a technology that allows the lens to be focused without changes in the lens' external size. Maintaining size helps keep balance, and with special control of optical movement, lenses can focus closer and with more consistent image quality.
Silent Wave Motor technology is another development that has added considerably to the Nikon lens selection. This step represents a significant expansion of Nikon's use of this advanced technology.
The G-type design is primarily designed for the newest Nikon SLR models, including both 35mm and Digital, all of which include a Sub-Command Dial, from which aperture control is possible. This design facilitates lens handling, and helps photographers keep a more positive grip on the camera as they use their right index finger to adjust aperture. This firmer grip and excellent balance will help photographers get sharper images, even as they adjust exposure and quickly shoot their pictures. Current compatible camera models include the D1x, D1H and D100 digital SLR cameras as well as the F5, F100, N80 and N65 film SLR cameras.
Distance Technology (included in D-type and G-type Nikkor) provides precision distance information from the lens. This information is incorporated into exposure calculations for both ambient light, flash illumination, and combinations of both, as in fill-flash photography. The distance information enables more precise calculations, leading to improved exposure control.
