About this deal

I often use it with the 1.4x teleconverter which does not detract from sharpness, but of course you lose one stop. Don't go for the 2x teleconverter, it seems to make the lens too soft. At the wide end of this range, head and shoulder portraits show a nice perspective as do any portraits captured from longer distances.

Sigma 70-200mm f/2.8 DG OS HSM Sports review

At all focal lengths the Sigma 70-200mm f/2.8 DG OS HSM Sports produces a moderate amount of chromatic aberration, typical of a high quality zoom lens with this focal range. At f/2.8, mild cat's eye bokeh, a form of mechanical vignetting illustrated by the CE sample, can be seen in the corners throughout the focal length range. I usually make the latter my default because fast usually proves similarly accurate for me (I didn't perceive a difference with this lens) and ... I like fast. Unless one is primarily using manual focusing, a lens' autofocus accuracy is very important for realizing the image quality a lens is capable of producing, especially with the relatively shallow depth of field this lens can produce at 200mm and f/2.8. The Siemens-star test-targets are shot at a distance of 40x focal length (i.e. at 4m for 100mm f.l.). But performance of lenses also depends on the shooting distance. Therefore I do another series of test-shots of a landscape dubbed the “Unremarkables” where you can measure distances in km, not meter. Processing was done in Lightroom 4.3 from RAW at Adobe Standard settings. Noise-reduction is set to 0, sharpening to 70/0.5/36/10, with no extra tone, color, or saturation-adjustment. There’s no tinkering with vignette-control so you see it here as it is produced by the lens. Focus was acquired at the largest aperture in contrast-based AF and not changed for other apertures.

These figures are recorded with all in-camera aberration correction disabled. In real world shooting, this lens is unlikely to generate noticeable levels of fringing. Differentiating between the zoom and focus rings is easy (even with gloves on) thanks to the large space between them and the tapered slope found in the center of the substantially-sized zoom ring.

The Hyper Sonic Motor (HSM) ensures a silent, high-speed AF function as well as full-time manual focusing capability for Sigma, Canon, and Nikon mount lenses. The lens can be used with the 1.4x EX or 2.0x EX APO Tele Converters (optional), becoming a 98-280mm f/4 Autofocus telephoto zoom lens or a 140-400mm f/5.6 Autofocus telephoto zoom lens respectively. His expertise with equipment doesn’t end there, though. He is also an encyclopedia when it comes to all manner of cameras, camera holsters and bags, flashguns, tripods and heads, printers, papers and inks, and just about anything imaging-related. The Nikon shows slightly less vignetting over the entire focal length range, has less barrel distortion at 70mm and better flare performance at that focal length as well (the two lenses are more similar at other focal lengths in those regards).A 70-200mm lens is my most-used studio lens, working especially well for product images and many other general studio applications. This lens features a highly effective dust- and splash-proof structure with special sealing at the mount connection, manual focus ring, zoom ring, and cover connection, allowing photographers to work in all types of weather. At 70mm f/2.8 it manages 3,817 lines on a center-weighted evaluation, a very good result, and while the edges aren't quite as crisp, they're still a strong 3,340 lines. Resolution is just shy of excellent at f/4 (3,913 lines) and levels out at f/5.6 (4,064 lines), f/8 (3,999 lines), and f/11 (4,071 lines). There's a loss of resolution starting at f/16 (3,691 lines) and continuing at the minimum f/22 aperture (3,026 lines). This is caused by diffraction, an effect that scatters light passing through a very small opening. If all of the wavelengths of light in the visible spectrum refracted identically, a lens designer's job would be a lot easier.

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.Optics: 22 elements in 17 groups compared with 21/16 elements/groups for the Nikon. 17 groups have 34 air/glass-surfaces that produce a lot of opportunities for flares and ghosts. The cross-section shows a lot of special elements: five low dispersion elements. [0] Thus, holding the lens with comfortable access to the zoom ring means the right hand must play a support role for a less-than-optimal scenario. However, the mounting ring itself is not removeable and its stub protrudes by about 12mm (half an inch) from the circumference of the barrel, even when the foot is removed. The lens itself is one of the biggest and heaviest in its class, being 94.2mm in diameter with an oversized 82mm filter thread, rather than the more usual 77mm. Weighing in at 1,805g, it’s around 300g heavier than most current competitors. Performance The Nikon mount version of this lens includes an electromagnetic diaphragm mechanism that allows it to receive the appropriate signals from the camera body. This feature ensures precision diaphragm control and stable Auto Exposure (AE) performance during continuous shooting. Usually a lens can be made compatible by the manufacturer via a firmware update, but this cannot be guaranteed.

70-200mm F2.8 DG OS HSM – Sigma UK

Still, these are one of the most useful classes of lenses available and they are well worth the investment and effort to use. Weight: 1,430 g (50.4 oz.) vs. 1,540 g (3.4 lb.) of the Nikon. Together with a full frame body you’ll be schlepping 2.3kg around. [0] As illustrated above, the effective angle of view changes considerably as the focus distance changes.The first three examples are 100% crops while the second 200mm example and "CE" example are full images reduced in size. There was really one thing only that made me sell the Sigma 70-200 after only two weeks and that was the poor sharpness at f2.8. I feel it was more so at both ends of focusing range. It also displayed a faint halo around brighter objects that were just out of focus.
