Product Description
The 28-300mm F3.5-6.3 MACRO lens covers all the focal lengths from 28mm wide angle to 300mm telephoto with 10.7: 1 high zoom ratio as well as macro capability. 28-300mm F3.5-6.3 MACRO packs a lot of performance in a compact package with ultra compact dimensions that make this lens the ultimate traveling companion length. The 28-300mm F3.5-6.3 MACRO lens feature 2pcs Special Low Dispersion SLD glass elements and 4pcs 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 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, with a reproduction ratio of 1: 3. This design allows for stability and compactness in design as changes in focus are made in an internal lens grouping. This also gives the advantage of a non-rotating front lens assembly, which is of great benefit when using polarizing filter and Petal-type hood. 28-300mm F3.5-6.3 MACRO lens is equipped with a zoom lock to prevent the lens from creeping due to its own weight, and to offer protection whilst the lens is being carried.Electronics:
