Used Sigma 24-70mm f/2.8 EX DG HSM

The Sigma 24-70mm f/2.8 EX DG HSM is the latest version of the f/2.8 lenses put on the market by this manufacturing company. Its structure makes it compatible with all Nikon, Sony, Canon and Sigma cameras. Only devices from the manufacturer Tamron are an exception. This is one of the most affordable 24-70mm f/2.8 lenses available on the market. At the same time it is characterized by an excellent quality/price ratio because it guarantees sharp images with good contrast. This model has a very wide focal length (24-70 mm), so it is truly versatile. For example, a focal length of 24 mm is the ideal solution for taking shots indoors, landscapes or in narrow places. In contrast, a focal length of 70 mm for portraits. The f/2.8 aperture, however, ensures a good rendering of details, also with regards to the background of the frames. This is especially true when shooting after dark or indoors. Another aspect that you need to keep in mind is that the sharpness of the image tends to worsen as the focal length is increased. Therefore the best results are obtained when you set this value to 24, 28 or 35 mm. However, distortions are less noticeable if you use an APS-C camera. Finally, please note that this Sigma device integrates a rounded 9-blade diaphragm. This is an element capable of increasing the quality of the image because it allows you to have a pleasant blur in the out-of-focus areas, thus increasing the final contrast.
