Minimum focusing distance of 20cm (7.9") and maximum magnification of 1:2.3
This lens has a minimum focusing distance of 20cm (7.9") throughout the entire zoom range. Maximum magnification of 1:2.3 enables close-up photography like a macro lens. It has a 3cm (1.2") working distance between the lens and subject and it is very convenient for taking close-up pictures.
Reduced Ghosting and Flare
The new multi layer lens coating and lens design reduce flare and ghost, which is a common problem with digital cameras and also creates an optimum color balance through the entire zoom range.
Aspherical lens elements & SLD lens
A Special Low Dispersion (SLD) lens and two aspherical lens elements provide excellent correction for all types of aberrations and produce a high level of optical performance throughout the entire zoom range.
F2.8mm (at 17mm focal length)
This lens offers a large aperture of F2.8 at 17mm wide angle and performs superbly even in relatively low light conditions indoors or at dusk.
Inner focusing system
Because the front of the lens does not rotate, circular polarizing filters and a petal-type hood can easily be used. An inner focusing system eliminates front lens rotation, making the lens particularly suitable for using the petal-type lens hood supplied and also circular polarizing filters.
A magnification scale is displayed on the lens barrel, ensuring ease of use.
Zoom lock switch mechanism
A zoom lock switch mechanism is provided to prevent the lens from creeping due to its own weight, and to avoid the danger of the lens receiving a shock while it is being carried.
HSM (Hyper Sonic Motor) for Nikon Mounts Only
The Incorporation of HSM is capable of autofocusing with all Nikon DSLR cameras.
