See Also: Sigma DSLR Lens Reviews (Discontinued)
Sigma manufactures more DSLR camera lenses than any other lens manufacturer in the world. And their latest models have been impressive.
There are older Sigma lens models that I have really liked and recommended (including the 85 f/1.4), but historically, I have not been excited by most of Sigma's lens models. That attitude has been changing.
With their new Global Vision Lens lineup hitting the streets, lead by the 35mm f/1.4 and 120-300 OS, I am quickly becoming a Sigma fan. These latest models are delivering good AF accuracy and very good image quality in an impressive-looking and mechanically-excellent package. With the Sigma Dock, these new lenses are now user-updatable for ultimate dialed-in performance. Sigma is a lens company to watch.
Liked by everyone is that Sigma lenses are typically value-priced.
Sigma lenses are available in Canon, Nikon and other brand mounts with the DC models being compatible only with APS-C/1.6x/1.5x sensor format cameras.
