Lenstip reviews the Sigma 18-125mm f/3.8-5.6 DC OS HSM and writes;
Pros: sturdy body for this class, very good image quality at the center of the frame at all focal lengths, good image quality at the edge of the frame in the range 18-70, the lowest distortion in this class, the lowest vignetting in comparison to the competition, sensibly corrected coma, quite good work against bright light, silent, fast and accurate autofocus, efficient image stabilization. Cons: worse image quality at the edge of the frame at the maximum focal length, large distortion at the wide angle. “
rating: N/A reviews the Sigma 18-125mm f/3.8-5.6 DC OS HSM and writes;
“The Sigma AF 18-125mm f/3.8-5.6 DC HSM OS is an interesting lens with a couple of high and lows which is quite typical for such extreme zoom range lenses. The resolution characteristic is generally decent – only the soft borders at 125mm may be really objectionable. The vignetting could be better at 18mm and 125mm at max. aperture but frankly that’s also nothing out of the ordinary in this class. Distortions as well as CAs are comparatively well controlled. “

The-digital-picture reviews the Sigma 18-125mm f/3.8-5.6 DC OS HSM and writes;
“I was able to make sharp images at slower shutter speeds, but the keeper rate was very low. Respectively, I can make occasional sharp images below my rule-of-thumb non-IS shutter speeds as well, so the improvement amount remains similar. Interestingly, there were a good number of OS-on images in my test that were very blurred at shutter speeds faster than should have been needed for sharp images.”

Sigma 18-125mm f/3.8-5.6 DC OS HSM User Reviews

Versatile, good performing and affordable, but beware potential autofocus problem | Rating: ★★★★☆
“The OS works pretty well, and I was able to take two perfectly clear hand held shots at full 125 mm telephoto at only 1/15 of a second, though I had to use my best technique, as I suspect at full tele it’s not hard to overwhelm the OS. Two more identical shots taken without OS were both blurry…” – by S. Florio

Just received this lens! First Impression | Rating: ★★★★★
“This is the first Sigma lens I got. Very good built quality. Hood is included and can be fitted front and back position. The construction is much solid compare to 18-55 kit lens. A bit better than the 28-135mm kit lens and size and weight about the same…” – by M. Hsu

Excellent all-around lens | Rating: ★★★★★
“I bought this to replace the 18-55mm kit lens for the Nikon D60. Nice balance on the D60. Focuses fast. OS makes a clear difference in low light. I chose this over the slightly larger 18-200 OS HSM Sigma to keep the size and weight down.. in fact, the zoom range beyond the Nikon kit lens was just the thing that I was looking for in a compact lens. Very pleased so far.” – by E. J. Pershey

I guess I got a good one.. | Rating: ★★★★★
“I’ve taken 74 pictures so far and just now viewed them on my computer. Awesome! I love the color and crispness of them. I’m not even close to a professional photographer. I use my XSI to take pictures of my 16 month old son and that’s it so take my recommendation for what it’s worth. It seems to me though that if you get a good “copy” you will be extremely pleased.” – by J. Carr

Affordable versatile lens | Rating: ★★★★★
“I bought this lens for my Canon 40D. I like its versatility- the zoom range of 18-125mm makes it suitable for most photographic opportunities. The lens is solidly built, and performs well. The autofocus is quick and accurate on my camera, and the image stabilization is helpful in low light. I’m happy with the image quality as well – pictures seem nice and sharp with plenty of snap.” – by John M. Bacheller

Worth every penny | Rating: ★★★★★
“This is the perfect wedding reception/walkaround lens for me. Sharp enough to get the job done, light enough to not kill your shoulder/neck. Yes, the OS makes noise. No, it’s not really an issue. No, it doesn’t seem to really drain my battery noticably faster.” – by J. Murdock
