Excerpt: I purchased this lens for use on my Nikon D5200 and have been extremely pleased with its performance. It is an ideal upgrade to the kit lens that came with the D5200, is fairly compact and has a broad zoom range.
Pros: Consistent Output, Durable, Fast / accurate auto-focus, Strong Construction

Summary: Less than half the cost of the OEM product of equal functionality. Cnet posted an excellent review on this product in 2013. I bought this couple of weeks ago and used a few times with excellent results. Am a Happy camper!
Excerpt: This is a good lens with crisp focus through its range but the focus is a bit slow! Great for stationary objects but too slow for action photographs. It is definitely one of the quietest focusing lenses I have ever owned though!
Excerpt: Not top of the line, but I get to eat this week, and I can put the money I saved by buying Sigma into my piggy bank for a new camera. No lens creep at all for me, though the zoom is tight around 80mm, maybe deliberately.
Excerpt: I love my a77, however, I don't love lugging it plus two to three lenses around on vacation. Last year I left it home and took my Canon G15 instead. The G15 did a good job, but, I kept wishing I had my Sony with me.
I now have a wonderful range of distance with sharp clear and color accurate ...

Summary: I really wanted an 18-250mm lens for my Nikon DSLR. The other brand lenses were more expensive than the camera body and kit I had originally purchased. I found the Sigma lens here for much less money. I was wary because of the price difference.
