وصف
This digitally optimized zoom lens provides a high zoom magnification of 10.7x. The new lens coating reduces flare and ghosting, a common problem with digital cameras and also creates an optimum color balance. The 10.7x zoom ratio covers a wide range of focal length from wide angle to tele-photo making this a highly versatile lens ideally suited for many types of photography. This lens features two Special Low Dispersion (SLD) glass elements and four Aspherical Lenses, to produce a high level of optical performance. Aspherical lenses provide excellent correction for all types of aberration while making a very compact construction possible. The 28-300mm F3.5-6.3 DG MACRO lens has a minimum focusing distance of 50cm at all focal lengths and is equipped with a macro mechanism for close-up photography at 300mm telephoto, allowing a reproduction ratio of 1:3. The zoom lock switch eliminates "zoom creep" during transportation, a convenient addition when traveling. The inner focusing system gives the advantage of a non-rotating front lens assembly, which is of great benefit when using polarizing filter and the matched Petal-shaped lens hood supplied.
