I am an enthusiast who enjoys taking pictures of the family. I did some research on a low light lens and found great reviews on this lens. The Nikon version is out of my price point so it was either Tamron or Sigma. I have not been disappointed with my choice.

great focal range/good for low light or no flash photography

the autofocus motor is a little loud; but not an issue for me

Great standard zoom! Didn't know what I was missing. Smaller than Canon's offering and much more affordable. Autofocus at first seemed iffy but was using in inadequate light. Turns out to be most accurate 3rd party lens I have.

Consistent Output; Fast / accurate auto-focus; Nice Bokeh

This is a great lens for the price. The focus ring is very sensitive, but that is the only downside.

This lens worked wonderfully for a wedding I recently photographed. Great pictures from this lens and my Canon 60D. About half the price of the Canon lens.

Fast focusing; Very sharp

heavy and bulky

I really like this glass, its big and beautiful! really smooth hsm motor. Really smooth zoom ring, very solid construction! Lens hood stays intact really good, clicks in nicely! I would recomend this to anyone who has a d7100 or lower in the dx range.

Was looking for a lens like this for a while.When I saw this lens on the internet, I did some research and decided to buy it. It is now my main lens for everything from landscapes to portraits. The only reason I didnt give it 5 stars is because the focusing motor is noisy for videos.

The out door pics were ok but the indoor low light pics were horrible at best every face had orange tint in them & poor low light in back/sides of the subject almost blacked out.I would never recommend this lens to anyone !

Poor in Low Light

Everything that's told about this lens is right and delivered; except two things. 1. OS - no OS as Sigma claims. I've been using this lens for 5 months and I can tell clearly that the lens sucks on this aspect. 2.

i like this product and i can recommend too

its work perfectly

This lens performs like my 50mm 1.8/f prime lens, but with the ability for zoom in and out. This is exactly what I needed and I'm so glad that a friend recommended it to me. It's so clear, has excellent bokeh, and feels very solid. I never leave home without it.
