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. If capturing environmental wildlife portraits or captive (zoo) wildlife, this focal length range may be perfect.

On this lens, the Smooth AF Priority makes a modest, but noticeable difference, slowing AF down slightly. Photographing mountains is an especially good use of this lens' focal lengths and it is so easy to take great telephoto landscape images that it feels (slightly) like cheating. This lens delivers very sharp results across the entire frame at 70mm f/2.8 and very little difference can be seen at 70mm f/4. The 144° of focus ring rotation is ideal for precision work at 70mm with adjustments happening slightly fast at 200mm, though not problematically so. If all of the wavelengths of light in the visible spectrum refracted identically, a lens designer's job would be a lot easier.The wide aperture also invites stopping action in low light and handholding the camera in perhaps even lower light levels. There's very little curvilinear distortion at the 70mm end, although there's a touch of more noticeable pincushion distortion at the 200mm. Again, however, this is only really visible when capturing subjects with defined linear details, rather than something that you'll see in general everyday use. While it is not an inexpensive lens, when the usefulness of the 70-200 Sports lens is considered, the price tag seems very good.

Portrait subjects can range from infants to seniors, from individuals to large groups (if enough working distance is available). There's about 1 percent pincushion distortion at 140mm, and the lens shows its sharpest results at f/2.8—3,003 lines using the center-weighted metric with edges that fall just shy of 2,700 lines. The lens gets better as the aperture is narrowed: 3,490 lines at f/4, 3,629 lines at f/5.6, 3,673 lines at f/8, and 3,569 lines at f/11. The lenses in this series continue to impress and gain popularity – just don't limit the lens' use to its letter designation. The diaphragm is electromagnetically controlled in the Nikon- as well as Canon-fit edition of the lens, helping to enable consistently accurate exposures even in rapid continuous drive modes. The Canon-fit version also benefits from compatibility with a full set of in-camera corrections for lens aberrations like lateral chromatic aberrations, distortion and peripheral illumination, not that you’re likely to need them.

[+] Moderate View Mode – This mode offers an excellent compensation of camera shake, and achieves very smooth transition of the image in the viewfinder. The composition of the image remains natural even when the angle of view keeps changing. These rubberized rings are sharply-ribbed for a high quality feel and are raised modestly above the barrel for ease of locating. Distortion stays steady at 200mm, but sharpness drops off dramatically. At 200mm f/2.8 the lens shows just 1,628 lines using our center-weighted method, with edges that are just 1,030 lines. You'll want to stop down to f/4 when zoomed all the way in if the light allows it. That will improve the overall score to 2,500 lines, but you'll still have to deal with fuzzy 1,355-line edges. The overall sharpness is better at f/5.6 (2,895 lines), but edges only sharpen by about 100 lines. You'll need to set the lens to a narrow aperture for the best performance—it's great at f/8 (3,211 lines average, 2,103 lines at the edges) and at f/11 (3,370 lines average, 2,614 lines at the edges).
