Sigma 70-200mm F2.8 APO EX DG Macro Lens
The Sigma 70-200mm F2.8 APO EX DG Macro Lens was introduced in 2008 and contains a very popular and functional focal length range in a very well built, well-featured and well-performing package.
Once you have had the opportunity to shoot portraits or sports with an f/2.8 long zoom lens, in this case a 70-200mm, you really never want to go back to what you were using. The overall tonality of images shot with the Sigma 70-200mm is outstanding. Colors are accurate, details are especially sharp in the middle range of apertures (f/6.3 – f/11) but a bit softer when shooting wide open (f/2.8 or f/3.5). The shallow depth-of-field created at f/2.8 is perfect for portraits, nature, and sports photography and the quality of the out of focus area, often called the ‘Bokeh’ of the lens, was very pleasing to my eye.
This lens uses with a HSM (HyperSonic Motor) variant of ultrasonic focusing for fast, accurate and near-silent operation. At middle to longer distances, focus was generally accurate and consistent, and was also fully able to track fast-moving subjects when used in continuous AF mode.
While the Sigma 70-200mm f/2.8 II Lens may not be a true macro in the sense of offering a 1:1 magnification ratio, many users will find it more than adequate for some basic macro work. From test shots taken in macro territory I discovered if you keep the aperture at f/6.3 or smaller you can get some very sharp images, but with wider aperture settings (f/2.8 or 3.5) the results are just way too soft to be useful.
