The Sigma 70-200 is a popular choice for many serious photographers because of the various features it comes with. It comes with a constant aperture that will make it easier for people to capture photos in different situations. It is also good for taking pictures in lower ISO. This will come handy for shooting in and low light situation. This lens is great for action photography as well.
When it comes to color and contrast, the Sigma 70-200 is excellent. The creamy background blur is facilitated by the presence of the 9-blade apertures. The chromatic aberration is well controlled, but the flare is not so, especially in higher focal ranges. At the 200mm mark, you need to have the sun and other sources of bright light far out of their pictures so that they do not end up with flare that robs the photo of its contrast.
You will not have to worry about distortion when using the Sigma 70-200. The lens shows a little barrel distortion on wide end and pincushion distortion at 100mm, which increases as it reaches the 200mm focal length. When it comes to vignetting, there will be little shading from 135mm to 200mm when the lens is at f/2.8. This phenomenon is especially visible if you use it with full frame cameras.
In order to avoid such problems, it is important that you stop the Sigma 70-200 lens down one or two stops from the maximum aperture. The users will also benefit from the fast and silent autofocus thanks to the Hyper Sonic Motor (HSM). The HSM is not only crucial for internal focusing but also helps in internal zooming. The front element of the lens will not rotate, making it possible to use it with the petal shaped hood.

Besides the solid build, you will also enjoy the smooth movement of the focus and zoom rings. The best thing is that its compact size makes Sigma 70-200 a suitable lens for people who want to carry it around for a longer period.
While the matte finish is convenient for some people, it may end up making dirt, marks and dust easily visible. You will also get the Sigma 70-200 with a tripod ring that offers a better balance as well as a flexible option. The tripod mount is low profile and keeps the lens close to the head for balancing purpose. However, it does not offer adequate clearance for the fingers. Fortunately you can remove the tripod ring easily if you do not like it to be used with your Sigma 70-200 lens.
