Both the Sigma 28-70mm f/2.8 DG DN Contemporary lens and 24-70mm f/2.8 DG DN Art lens fill the popular role of the wide-aperture standard zoom and do so at prices that significantly undercut those of first-party options. So, which is right for you? This excellent video comparison takes a look at both to help you decide.
Coming to you from Stefan Malloch, this great video compares the Sigma 28-70mm f/2.8 DG DN Contemporary lens and 24-70mm f/2.8 DG DN Art lens. While the 28-70mm is $799 and the 24-70mm is $1,099, perhaps the most notable difference is that one goes as wide as 28mm and the other out to 24mm. While 4mm might not seem like a significant difference, when you are below 35mm, every millimeter is quite substantial. The difference between a 24mm and 28mm frame is rather notable, so be sure you do not need that extra reach on the far end. On the other hand, the 28-70mm lens is both shorter and only about half the weight of the 24-70mm, making it far more portable in addition to its more affordable price. Check out the video for the full rundown from Malloch.
