Review on 📷 Sigma 24-70mm f/2.8 IF EX DG HSM AF Zoom Lens - Optimized for Sony DSLR Cameras by Justin Wallace

As a sports shooter, I mainly use my Sony 70-200/2.8 for shooting money. However, I need a lens that allows me to get a wider angle, as well as some close-up shots when the athletes are almost face-to-face with me. For over a year I was quite happy with my Tamron 28-75/2.8, but the focusing was too slow. Note that the Tamron is a great lens. I would rate the image quality as good as the Sigma. He concentrated just a millisecond slower. But if faster focus speed doesn't bother you, then the Tamron is a lens worth the money. While saving for a Sony/Zeiss lens, I came across a professional photographer using a Sigma 24-70 lens for the same purpose. This photographer is a national sport shooter. In short, since my photography is going to be self-financed, I had to be realistic. The Sigma is an extremely sharp lens for my A700 (1.5x crop) for almost $600 less than the Zeiss. It met my basic expectations for faster focusing speed than my old screw drive Tarmon focusing lens. The HSM motor is virtually silent. The zoom ring is quite stiff, but I'm sure it will loosen with use. The filter size is 82 mm. So if you want to use filters with other lenses you might be out of luck as most other lenses in this class of faster zooms have a 77mm or smaller filter. The only major downside is that the zoom works differently than all my other lenses, four stars for ease of use. In fast shooting situations, when I shoot with the Sony 70-200/G and then use another camera with the Sigma 24-70, several frames are lost as a result.
