Do keep in mind that this is an APS-C lens which can be used on FF lens cameras but probably will result in vignetting at the perimeters.
I own this lens. I currently use the lens on a Canon70d. It is fantastic. If you plan on using the lens with a Sony camera purchase the Sigma MC-11 converter + Sigma USB Dock. With the USB dock you can upgrade the lens from use on a Canon camera, foe example, to best performance on a Sony. Then you can further fine tune the lens, if desired, to your preference as to how you like to focus. Probably sounds more difficult than it is but really it's not bad at all. The USB dock can be used on several of Sigma lenses.
