Excerpt: Over the years I have not been impressed with Sigma's lenses. The ones I owned lacked sharpness and produced dull looking colors. Then a year ago I read some reviews of Sigma's new Art series lenses and was impressed by the IQ of these lenses.
Pros: Durable, Easily Interchangeable, Fast / accurate auto-focus, Lightweight, Nice Bokeh, Rugged, Strong Construction
Excerpt: I use the lens on an Sony a6000, and it performs well. There are times when the lens hunts for the focus. Most times it is quick to find focus. The quality of the lens is very good especially when one considers the cost point. Overall, the lens is worth the modest cost and returns good value.
Excerpt: The lens is really a good deal for the money. It compares really well to other high quality glass of same focal lenght that i can use with my A5100 thanks to the various adapters. It is sharp, good contrast and colors.
Pros: Consistent Output, Fast / accurate auto-focus, Lightweight, Nice Bokeh
Excerpt: This lens is nice and sharp. Focus comes at decent speed. Great bokeh. Good in low light. I don't care for the smooth barrel, but that can be remedied by a silicone focus strap. As is common knowledge, the lens rattles when not powered due to the electromagnetic focus mechanism.
Pros: Consistent Output, Fast / accurate auto-focus, Nice Bokeh
Excerpt: Light, quick focusing and crisp. This lens freezes candids in my camera as it remains frozen on my camera. It is my favorite lens. Capturing candids and sports shots of runners, it has exceeded my expectations. Fast focusing and inobtrusive it carves faces out of groups with its bokeh.
Pros: Fast / accurate auto-focus, Lightweight, Nice Bokeh
