About this deal

The Tamron 70-200mm f/2.8 Di VC USD G2 Lens, another third-party offering, will be an attractive option for those interested in the Sigma 70-200 Sports lens.

One interesting thing to note is that when the Sigma and Tamron lenses framed our test chart identically at the 200mm mark, the Sigma lens was actually 2.36" (.72m) further away from the chart, indicating that it provides a slightly more telephoto view at 200mm. Containing a superset of the classic 85-135mm portrait focal length range, 70-200mm lenses are ideal for capturing pleasing perspectives of people. At f/4, about .8 stops of shading shows in the wider focal length corners and just slightly more (just over a stop) shows in the longer half of the range.What follows are near-center results (first column) followed by DX-corner results and FX-corner results on a D800. The D800 results from the DX-corner should be a very good approximation for performance on a 16MP DX sensor (like the D7000), because the pixel-pitch of both sensors are the same. But differences in the AA-filter and micro-lens-design of a D800 and a D7000 might yield different end-results. As with shading, so with distortion: Geometric distortion varied smoothly with focal length, from a maximum of 0.24% barrel at 70mm, to 0.22% pincushion at 200mm. You'll notice the distortion at the ends of the focal length range if you're shooting subjects with straight lines in them parallel to the edges of the frame, but on most subjects, it won't be noticeable. After flaring outward rapidly from the mount, the lens' diameter gradually increases until the objective end.

As hinted to, images captured with APS-C format cameras do not show shading nearly as readily and the barely-recognizable close-to-1-stop of shading in 200mm corners is essentially the only consideration in this regard. A great lens for sports photography. I use it primarily for soccer and basketball action shots. Images are sharp with good contrast. I also shoot with the lens hood at all times. A perfect lens for soccer and football size fields. You will need a monopod as it gets heavy over the span of a couple of hours of lugging it around. Focus times are fantastic. I never miss shots because of focus lag. Something that's particular impressive is control over chromatic aberrations, although with so many low-dispersive elements in the optical array, this shouldn't come as too great a surprise. Only very minor traces of lateral chromatic aberration can be seen towards the edges of the frame at 70mm, and there's even less at 200mm. More impressive is control over axial chromatic aberration the centre of the frame, which is virtually absent.

These rubberized rings are sharply-ribbed for a high quality feel and are raised modestly above the barrel for ease of locating. providing 1.4x and 2.0x magnifications of the original focal length while retaining the original minimum focus distance, translating to a 1.4x and 2x higher maximum magnification spec respectively. There's a lot to love about this lens. With excellent detail at even wider apertures, great control over chromatic aberrations, very effective image stabilisation and prompt autofocus, it delivers what the professional demands at this level. Great build and weather sealing make it even more competitive, as does that price tag. It's not a cheap lens, but you get an impressive performance for the money.

The zoom ring location is also a non-issue if focal length adjustments are not needed or not needed in haste. Manual focus is also possible, as is Manual Override (MO). With this latter feature, the user is able to continue using autofocus as normal, before making any final manual adjustments using the focusing ring around the lens. This is particularly useful when capturing moving subjects, which may move slightly just prior to capture. The F2.8 zoom lenses are the essential equipment for many professional photographers. 70-200mm F2.8 lenses in particular are expected to perform at their best in various challenging scenes, from news to sports, landscape, and portraits. The SIGMA 70-200mm F2.8 DG OS HSM | Sports has high optical quality, a tough design and excellent handling ―all of the features required by professional photographers and high-end amateurs. The all-round, ultimate 70-200mm F2.8 is now available.

The lenses in this series continue to impress and gain popularity – just don't limit the lens' use to its letter designation. Simply press a focus stop button and capture enough images to be stitched together during post processing.
