Excerpt: It is okay sharp, but when you using cameras that have very high resolution like 24mp, it is not sharp when zooming in100%.(center is really sharp, other than center, not really) focus is quit quiet and precise. focal range is quite versatile.
Excerpt: Packed well, shipped quickly. This lens is shockingly amazing. I headed to the park and put this lens through the test... macro on flowers, sharp on architecture... there are tall buildings adjacent to the park. I also had a model with me, shot her at the long end as well as wide.
Excerpt: looks very nice and well balanced with my K5IIs, does very nice pics. i didn't want the very best bulky lens but i wanted better quality than a kit lens. The Sigma is exactly what i hoped it be. for the price it's a no brainer.
Pros: Consistent Output, Durable, Easily Interchangeable, Fast / accurate auto-focus, Lightweight, Nice Bokeh, Strong Construction
Excerpt: I have been looking at this lens for a while and when I got an unexpected check in the mail from my previous employer for vacation time, I had to pull the trigger and get it. Not disappointed - I love it. Sharp, great color. Love the macro. Great lens for my Canon 60D.
Summary: Paired this lens with my Nikon D5300 on a trip throughout Greece and got some fantastic shots, both daytime & nighttime due to the image stabilization. This was the only lens I took on the trip, and the 17-70mm focal lengths allowed me to take all the shots I wanted.
Summary: I love the new generation Sigma lenses, including this one. Fast and tack sharp on a Nikon D7100 without any AF adjustment tweaking. Works great in low light. I prefer the extra 15-20mm on the long end over the shorter constant 2.8 zooms.
Excerpt: I use my lens for landscape photography. We are going to Grande Canyon in June so did a lot of research on type of lens that would be best to have for travel. I have only had a couple of weeks but my pictures are so much better than before.
Pros: Consistent Output, Durable, Fast / accurate auto-focus, Nice Bokeh
