Excerpt: I am extremely pleased with this lens, especially for the cost. I've had great shooting experiences already with it, and I would recommend it to others who want a high quality, affordable lens.
Summary: This is generally my go-to lens for many projects these days: event photography, landscapes, people, food photography. You name it. It's so great to have so much of a choice in f/stops as well as distance in one lens. It isn't too heavy, which is nice too. And it's nearly silent when focusing. The pictures are sharp and clear and well-saturated and don't seem to have any chromatic aberrations.
Excerpt: This is my first Sigma product which I paired up with a D5300. I have owned this lens for approximately three weeks and I have tested its performance in both daylight and at night. Out-of-focus areas have a soft satin appearance. I found that though at its widest the aperture is f2.8, it appears that f4 is the sweet spot throughout the focal range. At night it struggled a couple of times to focus, but once it "got the hang of it" it did not miss-fire again.
Pros: Consistent Output, Fast / accurate auto-focus, Lightweight, Nice Bokeh
Summary: Excellent, sharp, clear and did everything I was hoping for in low light. I used it with my Sony A77ii to take some interior pictures of the Mission San Xavier del Bac. I was more than pleased.
