Summary: Not super sharp, I was a little disappointed. I find that the Sony lenses just work better with Sony cameras. After shooting a bunch with this lens I feel that I'm kind of done trying to make the low end Sigma lenses work with Sony cameras (I have the e mount model). I never got SteadyShot to work with them, they are not super sharp, and this one doesn't seem to have any stabilization of it's own (thus I really wish SteadyShot worked with it).
Excerpt: This lens is everything that I expected from reading other reviews. It's sharp, quick focusing (but not lightning fast) and great bang for the buck. It's perfect for landscapes, interiors and hopefully, some automotive shots. The smooth focus ring is slick, but a minor complaint. A rubber band helps with grip. It's just right for my Sony a6000.
Pros: Consistent Output, Fast / accurate auto-focus, Lightweight, Sharp Focus
