OS is a great feature

Excerpt: I returned this lens. There was an issue with the auto focus motor. It continually ran and drained my camera battery quickly. I typically get days of shooting out of a battery and with this lens attached I got 3 hours. I could feel the motor focusing even when my finger was not on the shutter button, Very stiff to attach to my Nikon D7100<br /><br />The zoom photos I took with it were very nice and sharp and the stabilization feature is great .
OK for what it does but a lot of compromises if you want great images.

Summary: Overall I found the lens to be too slow and rather soft in focus at anything above 100 mm range. Could be I just got a bad one as I have other Sigma lenses that are really sharp. However zoomed out this is a very slow lens and you need good light to really be able to use it. Shorter range is not so bad and as a walk around lens that is where you'd likely use it most anyway.
Summary: Great walk around lens. Prevents the need to switch lenses in the field and avoids getting dust inside the camera. But... The amount of light coming in especially at long focal length is much less than the Nikon kit lens (70-200). It has a very difficult time focusing on moving subjects even when they are not moving fast and even with lots of light available. I've noticed some amount of flaws in the edge of most pictures at a variety of focal lengths.
Bulky but a suitable one lens solution for DSLR owner

Summary: Sold my DC 18-200mm with 62mm filter size for this slightly longer focal OS lens...sad to say I'm not accustomed to using a much larger diameter (72mm) grip and heavier lens. The extra 50mm on the long end is not worth the bulk - the OS is nice to have but if you have a steady hand or use a tripod, you won't need this feature.
Summary: I know that zoom lenses are not supposed to be as sharp as prime lenses. I really wanted to like this lens, but it is not as sharp as either of my Pentax zoom lenses (18-135 and 55-300). I was hoping to use this lens as a replacement for my Pentax 18-135, but I can't live with the degraded image quality. Lens distortion, CR and bokeh are all inferior to my Pentax lenses. The auto focus motor and size are positives for this lens.
Excerpt: I've been a Canon DSLR user since the DSLR's came to be. I decided to try out the main competition. While I did buy an expensive Nikon lens (28-300) that I'm still trying to like, I thought about trying either the Tamron or the Sigma. The Sigma won out because of the reviews.<br />My copy seems to be similarly unsharp through out its zoom range and from 20ft. to 300ft. Not "really" bad, just not good. At full screen on my computer, it's ok.
Excerpt: I bought this for my travelings. I wasn't expecting the best quality, just decent ones. Macro focusing isn't good at all. Taking pictures of things too close wouldn't work very well. Very blurry. Lens creep is soooo annoying. I had to lock it every time I'm on the move! Only good thing about this lens is that I don't have to change my lens while I'm out there. No more changing back and forth between 18-55 to 55-250.
Pros: Durable, Easily Interchangeable, One Lens Does It All
Summary: I purchased this as that everyday, walk around, do it all lens that everyone is looking for. Paired with a Nikon D5100 it makes for a nice compact kit for a day of street photography, the zoo, at the park with the kids, etc. My copies zoom ring moves lightly and smoothly up till about 80-100mm then becomes very stiff from there to 250mm. The focus ring in manual has no resistance at all and feels like plastic on plastic, easily moved with one finger.
Summary: I bought this lens because of its high-power zoom and silent HSM focusing system. The image quality is not bad at all and silent and fast HSM is very satisfactory. The problem is its size and weight. It's a little too big and heavy to carry. This lens may be already outdated and isn't worth what you will pay for it.
