Nice travel/all purpose lens.......2006-01-14
Okay, this is a cheap, wide angle almost superzoom lens. That said, it covers a very usable range, produces sharp images, has a solid build, and is light and easy to use. It is a good choice for a travel lens for an APS-C sensor dSLR (not for full frame). The bokeh is a little odd, but I can live with it. The AF can be a bit slow in poorer lighting (but many more expensive lenses suffer from this as well). I've not regretted the purchase. Highly reccomend.

Nice all purpose lens. Nice range........2007-02-27
I bought this lens for those times when all I want is the camera and one lens. There are times when its nice having every accessory known to man packed in a case on your back but who needs all that when attending a party or family picnic. I really like the 18mm end of the range but do see the benefit of reaching out further without a lens change which the 125mm end provides. I have read all the technical analysis most of which confuses me and comes across like splitting hairs. Maybe some of those reviewers can afford to spend hundreds more. It seems like just about every lens suffers from something. Capturing an image that pleases the PHOTOGRAPHER is what is really important and so far I have been very pleased with the results. The lens is being used on a Nikon D50 so I have NOT experienced any of the focus problems the Canon users seem to talk about. As far as focus speed and noise are concerned, I can't tell the difference between this lens and my other Sigma(2) and Nikon(1) lenses. I should mention that I did consider the 18-200mm lens but decided against it because the 18-125mm has been in production longer, doesn't stretch the technical limits as far, and costs about $100 less.
Excellent Lens!.......2006-04-20
I have a Nikon D50 with the 18-55mm lens. I wanted a lens that would handle most of my requirements without carrying multiple lenses. I considered the Nikon 18-70mm but wanted just a bit more on the telephoto end. The Sigma 18 to 125mm f3.5-5.6 looked like it would do the job nicely. Being a retired news and commercial photographer, I was concerned about the quality of the non-Nikon lens but after reading a number of reviews, decided to give the Sigma a try.
I'm delighted I did! I really like this lens! Colors are crisp and true. The lens feels solid and works very smoothly and, most important, it is needle sharp! There is a small sound when focusing but it's not objectionalble. Focus is quick and accurate even in low light conditions. Unlike the low priced Nikons, the Sigma has a metal mounting flange.
I wouldn't hesitate to buy this lens again. It does more than I expected for a very reasonable price!
beware.......2006-02-22
do a little research and don't be fooled. Sigmas are generally a hit or miss thing for the lens quality. And worse off if you travel with the camera..seals are not at all reliable. Last but not least go ito a store and compare the drive noise on this unit to any other brand...very very noise...sorry i can not recommend them. Nikon, Tamron, Tokina...I personally prefer Nikon and Tokina...good luck
Sigma 18 -125 f3.5-5.6 lens.......2004-10-31
I bought this lens to use with my Canon EOS300D. Buyers should beware of the noticeable vignetting - in my opinion this problem is not acceptable in a lens of this price. Sigma should have sorted this out before putting it on the market. On the plus side is the convenient zoom range and the compact size. I guess it depends on whether you consider these benefits outweigh the vignetting problems. Yes, it can be corrected with imaging software, but who wants to have to correct every picture that has an area of sky or other light subject matter in the corners?
Terrific all-purpose digital lens, but be realistic.......2004-09-10
I bought this lens so that when I travel using my Nikon D100 I could have an all-in-one zoom that would spare me the inconvenience of constantly changing lenses. I have not regretted this purchase, as for most situations the resulting photos are quite satisfactory. However, potential buyers should be aware that any lens that is designed to "do it all" involves compromises.
The lens balances well on an SLR body, is remarkably compact, and is well-made. It's not as solid, however, as an expensive professional-level zoom, so don't drop it! The petal-type lens hood works well to prevent routine flare.
Photos I have taken have been sharp and clear, with only a bit of softness at maximum aperture and at the longest focal lengths. The lens has a few shortcomings, however. In some lighting situations the color cast of digital images seems to be a bit "tan," tending almost toward sepia tones. This can be corrected easily enough in Photoshop (or whatever post-exposure program one uses). Perhaps a bit more annoying is that there is noticeable light falloff in the corners, a phenomenon that is most prominent in photos that include large areas of sky. Again, this can be dealt with in post-processing (mainly through slight cropping), but potential buyers should be aware of this issue.
The best thing about the lens is that it provides adequate performance at focal lengths ranging from standard wide-angle (what would be the equivalent of around 27mm. in a 35mm. camera) to basic telephoto (187 mm. at 35mm.) This makes it quite useful for general, "walkaround" photography, especially when one is traveling. If you want the absolute best in optical performance, however, you might find the lens wanting in some situations.

Great general purpose lens.......2007-09-09
For work I take a lot of photos with my Canon EOS 20D, and I needed an all-around, general purpose lens. The Sigma 18-125mm is a useful tool that offers good macro usage, nice wide-angle shots (with little vignetting), and is just a good all-purpose lens.
The zoom mechanism is a little louder than I'm used to, but it isn't distracting. The lens, as far as feel, is sturdy but lightweight.
Overall, this is an excellent all-purpose lens.
All around great lens.......2007-03-15
Although it's not the fastest lens, it's great for outdoor shooting. I love the range that it gives me so I don't have to lug around lots of focal lengths. I use this more than any other lens. And for the price, it's an excellent buy.
Doesn't focus.......2006-12-12
After using that lens for 2 years, I had to sell it. It simply doesn't focus properly, and this is for all the lenses, not just the one I bought, as I checked others in the store afterwards. Simply zoom in onto your picture you will notice that what looked to be focused is not. I bought another one from another manufacturer, and make comparison over a month trial, and indeed the lens doesn't have a very accurate focus. Plus the range doesn't exist in my other manufacturers because it's not easy to build a high quality lens for a cheap price with such a high range.
Very versatile lens with acceptable shortcomings........2005-08-10
The good:
Excellent value. Has a very wide range so I can do wide landscapes, great macro shots, and everything else in between. The lens is also very light and compact. Makes a great walkaround lens. I went on a 3 week trip with this as my only lens, and I was very happy with it. AF is a twitch off, but close to perfect. All pics are super sharp.
The bad:
Noisy, slow autofocus compared to the kit lens as well as the 28-135 IS USM. No full time manual focus, and the switch for AF/MF gets switched to MF a lot when I take it out of my bag. There's also some vignetting around the corners that's noticeable in really bright scenes.
All in all, I still think it's a great value and I definitely recommend it.
A great lens at a great price.......2005-06-28
after reading through all different reviews on what lenses to get for my Rebel XT, i decided to go with this one, and I love it! The color is great, and the quality of the picture is definitely better than the 18-55mm Canon lens that came with the kit.
like other reviewer said, if you're lookin for everyday lens at an affordable price, then this is a great lens for you. With its quality, and zoom range, you can't find any lens that is better than this unless you're willing to spend 500+.
UPDATE: After less than a year, the focusing mechanism went out of whack. when i switch to manual focus, the camera still wouldnt let me take pictures- eventually, the camera just give me an error code 99 and refuse to do anything with it. sent it in for service, and was returned to me in 3 weeks due to backordered parts. the lens now works great.
overall, i can't complain about the warranty service becuase i was not in a hurry to get it fixed.

Sigma 18-125 Olympus 4/3.......2007-07-05
Excellent travel lens. Pictures are sharp with excellent color rendition. Good value for the buck.
A great 4/3rds lens. Much better than the Olympus kit lens........2007-03-16
To say that this lens is superior to the stock Olympus E-500 14-45mm kit lens is an understatement. Fit and finish is excellent. This is one nice piece of glass.
For 4/3rds people looking for a "take-one" lens. This could be it.
I personally like the focal range which makes this lens ideal for nature photography (trees, water, leaves, fungi, flowers, etc...). Forget wildlife with this lens. For that you'll need at least a 200mm tele.
All things considered, this lens represents a true value in the 4/3rds world.
Beautiful lens for the price.......2007-02-17
This lens looked like the perfect fit for a walk around lens (whatever the hell that means. Are there crawl around lenses? Or sleep around lenses? Just figured Id use the buzz word) so I decided to pick one up. I have been amazed at the results it produces for just over $200 dollars. I use the lens on my E1 and could not be happier. Sharp as a tack, and great contrast. I noticed that another reviewer was dissapointed with this lens on an E500. Maybe that body uses a different metering system? Maybe his meter was set wrong? Dosent make sense. It aint no Zuiko, but it aint no $900 either. I have the 50-200 too, but this one is much quieter, and produces a generally better picture. I wrote to Sigma and told them that I would gladly pay another C note or two for more quality and speed. Why dont you too? I paid right around $200 dollars for my 50-200 Sigma. The 50-200 Zuiko was around $1200 but I hear it has dropped in price. They can stick them until they hit around 4 bills.
I so wanted this lens to work well... alas.......2006-01-28
(1/27/2006) Rarely have I anticipated a purchase so much. A real general purpose lens that I could use in nearly all situations. You understand. Those times you don't want to lug your bag around and swap lenses. Just a quick shoot. Well, I can tell you that this will not be the lens. Why? Well, the design is flawed. I've now tried two (Thanks Amazon for a liberal return policy) on my Olympus E-500 (great camera) and while composing a shot is just as easy as it with the Zuikos, at full zoom nearly all the shots are dark. Very dark. Even Outside. Even with Flash. It is as if that with the lens fully extended (it nearly doubles in length at full zoom), not enough light can hit the sensor. Man, what a bummer. Now between 18-80 (36-160 for the non 4/3rds crowd), the shots are just fine. Perfect in fact. But I didn't buy an 18-80. I purchased an 18-125, and I want it work as advertised and the sad truth is that it does NOT. So, sad to say, I'm returning the second one. In fairness, I own another Sigma lens (55-200) that works just fine. And Sigma clearly attempts to make an affordable lens (unlike Zuiko) which I find attractive. So bear in mind my review applies to this lens and this lens only. Bad Design. Try again Sigma, try again. I'm still in the market for a good all purpose zoom lens.
NOTE: I've since learned that you can salvage these dark images if you shot in RAW, and use Photoshop Camera Raw to bring the detail back. Doesn't change the design flaw, but again, if you're budget crunched and can handle shooting a RAW, you may be to work around the design flaw using the just described technique. If you shoot to JPEG, the detail is lost and you'll never get the shot back.
2nd Note(3/1/2006): I've since acquired the Zuiko 18-180 lens. It works great. If you are looking for an all purpose zoom, zoom in on this one (pun intended).
