Product Description

Style: Canon Digital SLR Cameras

The lens is equipped with Sigma's own unique 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. This system offers the use of shutter speeds approximately 4 stops slower. It also automatically detects movement of the camera and compensate for camera shake when shooting moving subjects such as motor sports. Its compact construction has an overall length of 88.5mm (3.5"), maximum diameter of 74mm (2.9") and weight of just 450g/15.9oz (Sigma mount). This lens has a minimum focusing distance of 35cm (13.8") at all focal lengths, and has maximum magnification of 1:3.8, making it ideal for close-up photography. SLD (Special Low Dispersion) glass, a molded glass aspherical lens and two hybrid aspherical lenses provide excellent correction for all types of aberrations. The super multi-layer coating reduces flare and ghosting. High image quality is assured throughout the entire zoom range.

Very good built quality.
M. Hsu
Overall, I'd say this lens is the Canon 18-135 plus HSM.
Mark Twain
And it does not allow "full-time manual focus".

(See my update at the bottom of this review.) After buying my Canon xSi I quickly concluded that I was not going to be satisfied unless I had a zoom of some kind to go with it. For a walk around lens, the modest 18-125mm range that this zoom offered, which is moderate wide angle to moderate telephoto, sounded very appealing. I am not all that keen on sports or wildlife photos, so I eschewed the available super zoom lenses, not just for cost but for weight, size, and image quality issues.

I've done pretty extensive tests on this lens, taking many tripod shots out my window in Chicago, trying different apertures and focal lengths, and comparing them to my two Canon lenses, and found it compared favorably. I found the Sigma's photos to be good looking and always in focus.

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.

I've taken a few hundred shots with this lens so far and have no focus problems. Focus is fast and quiet. I took a number of shots of seagulls in flight at 125mm, a pretty challenging focus situation, and every one was in focus.

At 18mm this lens is a tiny bit less sharp than Canon's well-regarded 18-55mm IS kit lens that came with the camera, but as you zoom in the Sigma gets better, particularly at 50mm. (see update below about this)

The telescoping part of the lens is very tightly constructed, with no looseness or feeling of imprecision at all, unlike the Canon kit lens. It has a zoom lock, but this doesn't seem to be necessary as there is no lens creep.

This is a new lens from Sigma. I could not find any detailed reviews on the net before I bought it. It's a well built amateur lens with a nice focal length coverage that's not available from Canon. It's significantly heavier than Canon's 18-55mm plastic kit lens, likely due to more metal and glass used in construction. The focus is reasonably fast compared to Canon's kit lens and slightly quieter. For those who are familiar with Canon's ring type USM lenses, however, the this HSM lens is not a ring type HSM. This means it's not as quiet or as fast as the true ring-USM. And it does not allow "full-time manual focus". You have to turn AF switch off to manually focus the lens. This was a little disappointment for me for a lens at its price range. Sigma could have used a ring type HSM. Another thing I noticed is that while the OS (optical stabilizer) can be switched on or off, the OS gyroscope seems to be powered on even when the OS is off. You can hear the little noise from the piezoelectric gyro. My concern is that it can still drain battery power when OS is off. Optically, I am not in a position to say much because I have a 8MP camera. It's certainly adequate for me. Overall, I am happy with it and sold the kit lens that came with my camera.

Not willing to spend $600 for the Canon 18-200 IS, but distrustful of the Sigma/Tamron 18-200s that have a max aperture of 6.3 at the tele end, I found that what I really wanted was something like the ol' 28-200 I used to carry on my film cameras.

That's when I picked up the non-OS version of this lens, and loved it. But I couldn't help thinking that the OS would be better for me, so I moved up to this one.

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.

Canon now has a version of this lens selling for about the same price from some sellers on Amazon, but I'm not taking chances on it. I _know_ this one works for me.

If you are like me and want a bit more reach than the standard 3x kit zooms (17-50, 18-55, etc) but don't like the price, weight, or optical compromises of a superzoom (18-250) then this is a great lens. The build is really excellent for a lens of this price. It has nice weight and feels solid and well put together and it comes with a hood. Autofocus is great. It is noticeably better than the Canon non-USM lenses, but not quite as smooth and quiet as a ring USM/HSM lens like the 85mm f1.8. It should be more than adequate for most people. Optics are a bit of a mixed bag, IMO. From 18-85, it is excellent - easily beating the 18-55 IS and 17-85 IS and as good as any lens in its price range. Past about 85mm or so, it starts getting a lot softer. I don't mean to say 125mm is unusable, but if you go out and shoot all day at both ends of the zoom, the wide shots stand out as incredibly sharp, while the ones at the long end are just OK.

So quick pros/cons list:

Pros:
Great build
great price
perfect zoom range
Fast AF
Really sharp and contrasty from 18-85mm

Cons:
Focus ring rotates during AF
Just OK optically from 90+

Style Name: Canon Digital SLR Cameras Verified Purchase
After doing alot of debating over what lens to get, (Sigma 17-70, 18-200, 18-250, Canon 18-135, 17-85, 18-200, some Tamron's) I finally decided on the Sigma 18-125mm OS HSM after reviewing a crap load of customer reviews on a myriad of websites. I got this lens to replace a Sigma 28-200mm DG lens, for the wider angle and OS HSM, and to use as a main stay on the camera (Canon T1i) over my 18-55mm IS kit lens. Just got it on the weekend and here are my first impressions:

- Build is great and solid, feels really nice.
- A bit heavy, but i like it so -- doesn't feel cheap.
- Images are okay so far...need to play with it more.
* BUZZING/HISSING NOISE!!!

My only BIGGGG gripe is that the OS makes a constant noise, even when OS is turned off. At first reading reviews, it was mixed, some people said it doesnt matter, others said its annoying. For regular picture taking only I don't mind it....BUTTTT and it's a BIG BUT... IF YOU TAKE VIDEO with your camera, you hear the constant buzz/hiss from the lens in the video! :( -- this is a real big disappointment that the noise can be heard in videos, it's making me second guess my purchase. Maybe i should stick to Canon lenses if Sigma's OS's all make the hissing noise.

*UPDATE*
- This lens drains the battery life QUICK -- due to the OS continuing to running for 1min after u take a picture. Retarded!
- Sigma customer service/technical help -- is not helpful at all.
- Would return this lens if I had purchased it locally. Shipping back to Amazon is a pain.
