About Sigma 18-250mm

18-250mm F3.5-6.3 DC OS HSM...

An extended range Zoom Lens with Hybrid Optical Stabilization and Hyper-Sonic Motor, Sigmas innovation is in the 18-250mm F3.5-6.3 DC OS HSM 13.8:1 extended range zoom lens.

The DC lens is a dedicated digital SLR camera lens suited for APS-C format, and HSM (Hypersonic Motor) ensures quiet and high speed AF as well as full time manual focusing capability. Four Special Low Dispersion glass elements and three Aspherical lens elements provide excellent image quality throughout the entire zoom range.

This 18-250mm f/3.5-6.3 DC OS (Optical Stabilizer) high power zoom ratio lens is exclusively designed for digital SLR cameras and is capable of covering a wide range of focal lengths from wide angle to telephoto.

It is equipped with Sigma's own unique technology of OS (Optical Stabilizer) function. This function uses two sensors inside the lens to detect vertical and horizontal movement of the camera and works by moving an optical image stabilizing lens group, to effectively compensate for camera shake.

It automatically detects movement of the camera and compensates for camera shake when shooting moving subject such as motor sports.

The super multi-layer lens coating reduces flare and ghost. This lens provides superior image quality throughout the entire zoom range.

An inner focusing system eliminates front lens rotation, making the lens particularly suitable for using circular polarizing filters and the petal-type lens hood supplied.

Nice walk around lens

This is a really nice surprise. Most people on forums seem to think that so called super zoom lenses are too much of a compormise to be any good. I am taking a long vacation and wanted a walk around solution. I received this lens and tried it out right away. The focus is almost as fast as the canon 17-55. When you are outside During the day or inside with a nice flash (like the 430 exII) the IQ is outstanding. As long as you understand the limitations of a lens like this you will be very happy!!

Looks better than it is

I am disappointed with the image quality. The images are soft and lack detail. There seems to be a lot of fringing and noise at ISO 400. This would be a good lens for someone to take for vacation photos that would not enlarge more than 4x6 or use on web. Images look good on the computer screen until you enlarge or crop them at 100%

So far, really pleased.


from Marietta, Ga  -  Photo Enthusiast

Haven't used the lens that much so far, but initial impressions are good: Pros: Quiet and quick auto focus Good image quality for landscape photography Good zoom range for a multi use everyday lens Cons: Heavy Stiff zoom ring/function

A Fine Lens - But Not For Me


from El Paso, TX  -  Photo Enthusiast

I really, really, really wanted to love this lens. I did a lot of research on my options in this pirce range and the fact it is built is Japan was a major selling point. THE GOOD: Well built with a sharp and clear visual through my DSLR. Operated smoothly and had a feel and look of quality. Quiet. THE BAD: I'm only guessing it was not a good match for my Nikon D7100. Auto-focusing seemed inconsistent and fickle at times on the auto mode. Exposures seemed unpredicatable in any auto mode. The color did not match the quality of my Nikon lenses. One big surprise was that my 200mm Nikon got me just as close to a subject as the 250mm Sigma. I really wanted to love it, but after 1000 test shots - I decided to stick with Nikon products and will simply have to save up more cash to do so.

I needed this.


from Wisconsin  -  Photo Enthusiast

This keeps my lens switching in the past. So far the images are clean, crisp and sharp. Sigma makes fine lenses.

Good walk-around lens with some issues


from Jackson, MS  -  Casual Photographer

I bought this lens to replace my kit 18-55 and 55-250 canon lenses. Pros: 1) Great range. No need to swap lenses on a casual photography outing. 2) Well built and looks like it can take a beating 3) Included lens hood is a bonus. Cons: 1) Fine focusing at longer zoom is not great. unless you are absolutely still forget taking any images at near maximum zoom without a tripod. 2) Lens is slow to focus especially in low light.


Shoulda bought two!


from Buena, NJ  -  Photo Enthusiast

I really haven't had time to assess this lens properly. So far, its relatively small, feels great and functions as advertised. For $260. with waranty, this was an exceptional purchase. (I should've bought two).

OS is a great feature


from North East Texas  -  Semi-pro Photographer

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 The zoom photos I took with it were very nice and sharp and the stabilization feature is great . I also like the lock to prevent lens creep. Not the best in low light. For the price its a nice lens mine just had a factory issue. Adorama has an awesome return policy and service!

Better than expected for the price


from So Cal  -  Photo Enthusiast

Overall, better than two kit lenses put together. On my D7000, it is bright enough. Surprisingly sharp throughout focal length. Auto-focus is fast, quiet, and accurate. It searches a little in low-light, but not too bad. Lens creep is a small issue, but the lens lock works well enough for me. Feels sturdy and tight (maybe a little too tight). The hood is nice, but it took me while to figure out that it won't lock in place unless the Sigma logo is on the bottom. Packaging is not fancy or careful like Nikon; my lens cap came wedged on crooked and there was no bag, but that's OK if it's not a sign of lens quality. I'd give it 4.5 stars if I could, but I rounded up because of the price. I'd buy it again in an instant. It will stay on my camera 90% of the time. The versatility is wonderful.


Great lens

I'm not a pro, and this lens is really great for beginners!

I like it!


from Chicago, IL  -  Casual Photographer

I regret not buying this one earlier for my Nikon 5100. My original Nikon 18-55mm lens did its job, but a lot of times it doesn't give me the reach that I want to get to. I could have bought another longer range lens, but didn't want to carry mutliple lens. This one gives what I need. I have this one for about a month, and so far I am very happy with its performance.

Does not work with full frame camera's


from Orlando, Fl  -  Semi-pro Photographer

WARNING! If you have a full frame camera do not buy this lens. compatibility check says this lens will work with my Canon 6D. Only if you want a circular photos from 18mm- 100mm and a vignette around each photo at 250mm.


Questions & Answers Powered by TurnTo®

Questions about this item:

Shopper  Why Did You Choose This?
Abraham K  Best deal for the money. Made in Japan. Rival lens 18-270 is made in China
Bertrand D  Does this lens fit the mounting on canon full frame bodies such as the 6D?
Vincent B  If you go to the Sigma site you can find a listing of which lenses are compatible with the 6D.
ML 2  Does the Sigma 18-250mm f/3.5-6.3 DC OS works well on the EOS 5D mark ii??
MEREDITH M  I think that the lens is designed for cropped-sensor cameras and would not be suitable for the 5D mark II which has a full frame sensor (I believe).
