10/28/2022 0 Comments Sigma serial numbers lensOptical TestingĪs is our practice with 2x zooms, these lenses were tested at both ends (we do middle focal length testing on 3x and longer zooms). If you’re interested in why you can read about it in the addendum. The test I’m showing you today is my second set of 10 copies of the lens, not the first 10. It’s complex, it’s arguable, but it deserves mention that you should probably consider the graphs in this post ‘close, but might not be exact’ at the outer edges.Īlso, I’ve violated my usual testing protocol for the first time, and I think you should know that. One other thing needs to be mentioned when we test full-frame f/2.8 lenses wider than 16mm we are either right at, or possibly past, the limits of our machine. Of course, the usual ‘this is not a lens review, it’s an optical test’ stuff applies to this post. Second, 16mm is not 14mm, they are very different beasts (not to mention, most 16-35mm zooms are actually 17mm at the wide end). Yes, I’m aware someone is going to make noise about other lenses. So I thought that the new Sigma should be as good as the Nikon 14-24mm and better than the Tamron 15-30. The Sigma, at 1150 grams is a bit heavier than the Nikon (1000g) and about the same as the Tamron (1100 gm). The Sigma is less expensive than the Nikon by $400, but $200 more expensive than the Tamron 15-30mm f/2.8 Di VC USD. Sigma isn’t filling a void here Nikon already has an excellent 14-24mm, and Tamron has the not-quite-as-wide but really close 15-30mm f/2.8 Di VC USD. It remained the gold standard of wide zooms for years. It was a revolution wider and sharper than any other wide zoom made at the time. Years ago, Nikon came out with their Nikon 14-24mm f2.8G ED lens. And somewhat because this became an exciting learning experience that I’ll tell you about at the end of the post. Why then, you may logically ask, am I just now writing it up? Well, partly because I have jobs that like, you know, pay me to do stuff. I wasn’t sure what to expect from the Sigma 14-24mm f/2.8 DG HSM Art, so I was eager to test it and grabbed copies as soon as we had them in stock. The Sigma 24-70mm f/2.8 Art, on the other hand, I thought was adequate. I thought the Sigma 24-105mm f/4 Art was the best 24-105mm I’ve ever tested (and I hate testing 24-105s). I’ve been more mixed in my opinions of Sigma’s Art zoom lenses. Most of you know I’m a big fan of Sigma’s Art prime lenses. They give superior optics at excellent prices just about every damn time.
