Product Description
The Sigma 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. The 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. Two-piece Special Low Dispersion (SLD) glass elements and four-piece Aspherical Lenses, produce a high level of optical performance. The 28-300mm f3.5-6.3 Macro lens feature two-piece Special Low Dispersion SLD glass elements and four-piece 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. Macro photography with a 1:3 maximum photography ratio The 28-300mm f3.5-6.3 Macro lens has a minimum focusing distance of 19.7 inches (50 centimeters) at all focal lengths and is equipped with a macro mechanism for close-up photography at 300-millimeter telephoto, with a reproduction ratio of 1:3. Inner Focus System 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. The "Zoom Lock" device prevents the zoom setting from being changed inadvertently. The 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. DG Lens These are large-aperture lenses with wide angles and short minimum focusing distances. With an abundance of peripheral illumination, they are ideal lenses for Digital SLR Cameras whilst retaining suitability for traditional 35mm SLRs.
