Sigma’s fast-paced telephoto offering to DSLR users
A full-featured, action ready telephoto zoom lens, this Sigma 70-200mm f2.8 is going to make some Sports and wildlife photographers very happy, at a very reasonable price. The large f2.8 aperture is on offer throughout the zoom range, allowing for flexible depth of field control and handheld, available-light shooting. Full-frame cameras and APS-C format cameras can be paired with this sturdy lens, the latter resulting in an approximate zoom range of 100-300mm, even more suited to capturing distant objects, on the sports field or the open range.
Along with a large constant aperture, allowing for shooting with faster shutter speeds, the Sigma 70-200mm has a built-in optical stabiliser for counteracting any movements or bumps, resulting in images free from the effects of camera shake. An overall more-pleasing user experience is possible thanks to this stabiliser, with users being presented with a more steady image when looking through their viewfinder. Finding the right focal point is easy with this lens, either with the Lightning fast HSM autofocus, or the available full-time manual focus. For tracking a fast-paced subject you can utilise the speedy focus system and you can then make any necessary critical adjustments by hand, without having to change a setting on your lens.
What's gone into building this reliable performer?
Despite all the extra-functionality and performance improvements, Sigma have managed to decrease the size in this lens, with it measuring just 7.8” in length. In the optical construction is 2 FLD glass elements and 3 SLD glass elements, both of which help to correct for aberrations and distortions, and supply excellent imaging throughout the entire zoom range. Flare and ghosting is likewise corrected through Super Multi-layer lens coatings, resulting in accurate colour representation and pleasing contrast levels. A rounded 9-blade aperture diaphragm promises attractive out-of-focus areas that are created by the previously mentioned f2.8 constant aperture - this is a solid and reliable performer to add to your DSLR kit.
