High Image Quality with a Switch Allowing for Macro Shooting
The Sigma 70-300mm APO DG f/4-5.6 Macro Lens is just one of several telephoto zoom lenses which incorporates an auto-focusing motor in the lens allowing it autofocus on all Nikon Entry Level DSLR cameras. Also, with the lens motor built, focusing is quieter and faster.
This 70-300mm lens is an Apochromatic compact tele zoom lens which incorporates a pair of Special Low Dispersion (SLD) glass elements into the front lens array, plus there's a single SLD glass element contained within the rear lens array, to diminish chromatic aberrations.
This Sigma APO MACRO lens for Nikon features telephoto-macro function, optimized specifically for DSLR cameras. This particular telephoto zoom lens delivers high image quality with a switch allowing for macro shooting between 200mm to 300mm and has a maximum magnification 1:2 capability. In order to deliver the highest quality pictures, this APO lens was manufactured using (SLD) glass which is engineered to minimize color aberrations.
While the refractive glass index depends upon the light's wavelength, color aberration happens when dissimilar colors develop images at unique points. This situation often happens with telephoto lenses, however the (SLD) glass plus Extraordinary Low Dispersion (ELD) utilized in the SIGMA 70-300 helps in compensating for these color aberration, in doing so allows it to create sharp photographs.
This Sigma DG lens is perfect for DSLR Cameras while retaining usability on traditional 35mm SLR cameras. DG lenses are engineered to mount on 35mm film SLR cameras, DSLR cameras, and cameras featuring 'full frame image sensors. Additionally they work on the APS-C Cameras mentioned above as the resulting image circle on image sensor is bigger than required.
The DG lenses contain improved light distribution starting at image center all the way to the edge, in particular at wide-open aperture, in comparison with fast standard wide-angle lenses. In digital photography this is important, although useful in 35mm film photography, particularly when using slide film. The lenses elements also feature the Sigma super multi layer coat reducing internal reflections anf flare from the extremely sensitive image sensor surfaces.
If you need a low light lens, this isn't it. If your primary objective is to take pictures in low light situation such as wedding and concerts, then get the
50-150mm f/2.8 HSM or the 70-200mm f/2.8 HSM instead.
Note: (The Nikon Verson Only) includes built-in motor and will on the
Nikon D40/D40x, Nikon D60,
Nikon D3000, Nikon D3100, Nikon D5000
and Nikon D5100 Cameras.
The Sigma weighs much more, is longer, and makes more than the Nikon 55-200 and
dissimilar to the Nikon 55-200, the lens front and thus the filter rotates and moves to and fro while focusing. I might be able to cope with that dislike if the Sigma allowed me move in a bit closer. However, shooting handheld and evaluating the results I quickly realized that 200mm using VR and cropped results in better images and just as crisp as 300mm without having VR which just photographing stationary subjects.
