reviewswhat are people saying

"The quality of the lens feels great and you come away feeling like you're getting a lot for your money. The ability to lock it into 17mm is handy for transportation and twisting it onto your body. The AF is audible but not loud enough to make it seem cheap."

"It's razor sharp, even wide open. If that's all that matters to you in a lens, stop, do not pass Go! and buy this lens. Bokeh is pleasing for its price range as well."

"AF is tempermental, that is to say, sometimes it is responsive, other times less so. I would say AF speed is average at best. Although I don't have any BF or FF issues. And yes, it's noisy, but that's to be expected."
