Sigma 18-250mm f/3.5-6.3 DC OS HSM Reviews

SLRGear reviews the Sigma 18-250mm f/3.5-6.3 DC OS HSM and writes;
“The 18-250mm provided sharp test results, even when used wide open, to about 80mm. Wide open in the telephoto range, things start to get a bit soft, especially in the corners. Stopping down helps alleviate these issues. At the wide end, the lens performs very well. At 18mm and ƒ/3.5 we do note some slight de-centering but the central region is still very sharp at around 1.5 blur units. Chromatic aberration performance is fairly good for a lens in this category, showing some significant fringing in the wide-angle and telephoto ranges only.”

Popphoto reviews the Sigma 18-250mm f/3.5-6.3 DC OS HSM and writes;
“On the Pop Photo optical bench, the lens produced SQF numbers in the Excellent range for the 18-, 35-, and 100mm focal lengths. As is common for superzooms, sharpness and contrast dipped at the longest focal length, here down two levels to Good. Performance is just a tad below Tamron’s 18-270mm at the 11×14 magnification, our benchmark for sharpness and contrast. “

The-digital-picture reviews the Sigma 18-250mm f/3.5-6.3 DC OS HSM and writes;
“I am very pleased to report that the first copy of the Sigma 18-250mm f/3.5-6.3 DC OS HSM Lens I purchased retail focuses accurately – consistently. And with HSM (Hypersonic Motor) AF, it does so quickly, quietly and internally. The 18-250 focuses at least as fast as the non-USM Canon EF-S 18-200 and is slightly quieter. I found AI Servo AF performance to be good.”

Photoreview reviews the Sigma 18-250mm f/3.5-6.3 DC OS HSM and writes;
“A small amount of vignetting was observed with the widest apertures at all focal length settings. However, stopping down by as little as one f-stop virtually eliminated this problem. Flare and ghosting were generally very low, thanks to the internal surface coatings in the lens. We found no fault with overall colour or tonal reproduction, even with relatively strong backlighting.

Ephotozine reviews the Sigma 18-250mm f/3.5-6.3 DC OS HSM and writes;
“With most superzoom lenses, you may expect to see a drop off in performance as the lens is zoomed in. This Sigma 18-250mm optic still holds up well at 80mm, with very good sharpness across the frame at maximum aperture and outstanding clarity across the frame at f/8.”

CNET reviews the Sigma 18-250mm f/3.5-6.3 DC OS HSM and writes;
“Photographers often have to compromise when it comes to third-party lenses, particularly ones that cover such extreme focal lengths as the 18-250mm. This Sigma model is excellent value for money, offering good sharpness and performance, with a lengthy zoom.”

Shutterbug reviews the Sigma 18-250mm f/3.5-6.3 DC OS HSM and writes;
“During my tests I played with the zoom range to see the effect, shooting both setup and street shots in the process. I made some close-ups, which can be done as close as 17” even on the max tele side, which means you can get in quite tight on florals, etc. I also shot over the range of focal-length settings at max, medium, and minimum apertures and am happy to report that I detected no visible vignetting at any setting.”

Sigma 18-250mm f/3.5-6.3 DC OS HSM User Reviews

Best bang for your buck, | Rating: ★★★★★
“Very minimal nuance with my Canon L lens if you ever notice it at all. No wonder this is the Best Entry Level Lens: Sigma 18-250mm F3.5-6.3 DC OS HSM and has a TIPA award for 2009. Quick AF and razor sharp pics!!!! Anyone now can become a playboy photographer.” – by Abanquil Agbayani

Perfect for what it should be, | Rating: ★★★★★
“This lens is for walking around and taking nice pictures. The extra zoom is nice. The build quality is fine. The optic stabilization is OK, but I like the stabilization in the Nikkor better (but if you’re shooting in bright conditions or have a decent flash, this doesn’t really matter). “ – by D. Lawrence

Great Lens for a fantastic price, | Rating: ★★★★★
“This lens combines both a wide angle and a zoom capability, a must have for a photographer who is continuously on the move and do not want to carry with them many lenses for every occasion or purpose, its versatility is perfect in every kit. The picture quality is fantastic, I use it with my Sony A380, and soon enough with my Sony A900 (awaiting delivery). “ – by Sarie Asaad Arar

Sturdy easy to use full-range lens, | Rating: ★★★★★
“The super zoom is just awesome. Great picture quality! Especially the OS is beyond my speech. The only star I took off in terms of ease-of-use is due to the heavy lens would slide itself when carrying around without locking it. Not too bad, very acceptable.” – by Bonk

So far so soft, | Rating: ★★★★☆
“after a week of use I came to conclusion that sharpness is adequate for this lens’ intended usage. Surely the lens won’t win any sharpness contests but overall this lens represent very nice balance of image quality, features, versatility and build at a reasonable price. Still not quite a 5-star for some noticeable off-center softness, but it is a very solid 4. I wish it would let more light in to be more usable for indoor use, but competitors in the same price range aren’t better in that respect either. “ – by Valdemar

good lens overall, as long as you know its limitations, | Rating: ★★★★★
“the images are sharp enough for me, with the caveat that I am not a pixel peeper. I immediately crop and reduce the size of my pics once I get them on my computer. I was worried when I zoomed in on the pics in my camera that they wouldn’t be sharp, but they look great on my smallish computer screen, for the most part. The lens feels good in hand and I enjoy the heft, especially since it balances out my D80 with battery pack and external flash. No lens creep yet.” – by Michael Chen

Good purchase, | Rating: ★★★★★
“I am using a Canon t1i with this lens and i am very happy with picture quality i get. I only shoot in jpeg and image sharpness is enought for my needs. I tested the stabilization at 250 mm and it’s works great. For an everyday lens this is a good choice.” – by Alioune Ba

Best lens for your money for the casual photographer, | Rating: ★★★★★
“I am by no means a professional but I do enjoy taking great photos. I also enjoy not worrying about changing lenses all the time. The Sigma 18-250 gives me the ability to shoot wide or zoomed in within seconds. I would highly recommend this lens to anyone that is looking for a super zoom lens. Camera Body – Canon EOS Xti “ – by N. Chase

Bought it with fear; now very happy! | Rating: ★★★★★
“Nice bokeh, as usual Sigma lenses have creamy bokeh, which is a big plus for such zoom lenses. When in manual focus, the focus ring is very smooth. Good features, quality, price, and some minor cons. I was worried the most about its sharpness, but it turned out satisfactory. So I am very happy with it.” – by J. Wu
