This zoom lens was exclusively designed for use with digital Single-Lens Reflex (SLR) cameras and has a 1:6.9 zoom ratio. From wide angle to telephoto, this new zoom lens can capture a wide range of subjects. As there is no need to change lenses, there is no risk of missing those great shots. A Special Low Dispersion (SLD) lens and two aspherical glass elements produce a high level of optical performance through the entire zoom range. We used the most appropriate coating for digital products to reduce flare and ghosting caused by digital SLR cameras and to produce the best colour balance. This lens has a minimum focusing distance of 50cm (19.6in.) at all focal lengths and a maximum magnification of 1:5.3.
The lens is equipped with an inner focusing system which prevents the front element from rotating making it particularly suitable for Petal shaped `hoods and a circular polarizing filters. The lens is also equipped with a zoom lock that eliminates "zoom creep" during transit.
