Sigma 120-400mm f/4.5-5.6 Overview

  • 1Description

This Sigma 120-400mm f/4.5-5.6 DG OS HSM APO Lens is compatible with Canon EOS mount DSLRs; it's an ultra telephoto zoom lens ideal for nature/outdoor or sports photography. It has a minimum focusing distance of 59.1" (150cm) throughout the entire zoom range and has a maximum magnification of 1:4.2 making it useful for close-up photography.

The OS (Optical Stabilizer) system minimizes image blur caused by camera shake, and offers the equivalent of shooting at a shutter speed 3-4 stops faster. This allows handheld telephoto zoom shooting even in poorly lit conditions.

The use of the OS (Optical Stabilizer) system, HSM (Hyper Sonic Motor), APO apochromatic design, three elements of SLD (Special Low Dispersion) glass, and multicoated optics all enable this lens to provide a high level of performance throughout its entire zoom range, as well as versatility. A rear focus system insures quick, convenient manual focus and a non-rotating front barrel.

The improved DG lens design corrects for various aberrations. This lens is specially coated to get the best color balance, while cutting down on ghosting caused by reflections from the digital image sensor. The lens provides the utmost correction against lateral chromatic aberration, which is a serious problem for digital SLR cameras.

By adding the optional Sigma APO teleconverter, you can use this lens as a 168-560mm f/6.3-8 manual focus ultra-telephoto zoom lens with a 1.4X EX teleconverter, or as a 240-800mm f/9-11 manual focus ultra-telephoto zoom lens with a 2X teleconverter.

The OS system uses two sensors inside the lens to detect vertical and horizontal movement of the camera. It 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 HSM (Hyper Sonic Motor) system ensures quiet and high-speed auto focusing with full time manual focus override.
Three Special Low Dispersion (SLD) elements provide excellent correction for chromatic aberration.
Super Multi Layer (SML) coating reduces ghost and flare.
The lens design incorporates an inner focusing system, which prevents the front of the lens from rotating, thereby making it particularly suitable for use with circular polarizing filters and petal shaped lens hoods.

    Sigma 120-400mm f/4.5-5.6 Reviews

    120-400mm f/4.5-5.6 DG OS HSM APO Autofocus Lens is rated 4.4 out of 5 by 80.
    Rated 5 out of 5 by from Sharp lens, excellent value I ordered this lens as soon as B&H got it and have been using it on my Canon 40d. After several weeks operation I'm completely satisfied with it's performance. I tried it at an air show recently and obtained sharp images throughout the range. Image Stabilization works well as I got excellent pictures at full zoom without a tripod and during frequent panning. I never had a problem with autofocus on fast moving planes and zooming was always smooth and stable. The lens is heavy of course but was not a burden after a full day. This lens is considerably less expensive than the Canon EF 100-400mm f/4.5-5.6L IS and is highly recommended.

    Rated 4 out of 5 by from Just what I expected I am an enthusiastic amateur wildlife photographer who travels to remote places around the world. My stand-by lens was Canon 300 L with 1.4 teleconverter but no image stabilization. The Sigma 120-400 covers a wider range than the 300 and goes nicely with my Sigma 18-200. The OS stabilizer is great! I can use a light monopod instead of a tripod, much easier to carry in the jungle. The lens doesn't weigh much more than my 300 and costs half as much as Canon's 100-400 making it a great deal. Plus I got the 3 year warranty. I will be testing it out on a 5 month trip to South America and expect wonderful results.

    Rated 4 out of 5 by from Best for less First let me get this off my chest. There are a couple of reviews on this lens that are in my opinion false. To say this lens is not sharp is baloney. It is sharp! and Great for birds and wildlife in general. This lens in most of the shots I have taken are on par with Canon 100-400mm. And this lens cost much less. The lens is very fast and locks on in an instant. Yes it seems a bit heavy but very balanced and not that noticable. Sure you can try to impress your friends with pixel peeping a 5x7 photo blown up to bill board size and find flaws, as with any lens.however, I would rather spend my time showing off my great photos taken with the lens. when used with in it's means it is superb! Fast! and has great build quality. Sigma hits a home run!

    Rated 5 out of 5 by from Super good lens1 I am an avid amateur bird/wildlife photographer. I needed a long telephoto lens, and decided to try the Sigma 120-400 f/4.5-5.6 lens. I use it on a Canon Rebel T2i. I have had the lens only three days now, but have put it through a pretty good test of shots. the lens has exceeded my expectations. The clarity and sharpness are awesome, even throughout the range of focal distances. The OS feature is nice, but I feel a lens this size may require a tripod. I had no trouble getting it to focus on fast moving birds. I can't think of any negatives about this lens, and I highly endorse it.

    Rated 5 out of 5 by from Great Value-Pleasing Results I purchased this lens primarily to shoot sporting events and wildlife/nature images which is not my everyday forte. I had some concerns based on some of the comments about the quality of the image. But since this is not a lens I would commonly use, the price was more attractive to me than the equivalent Canon L. I love the lens. The lens OS works very well. I was able to take acceptably sharp handheld shots at sunset in warm low light. The AF is acceptably accurate, fast and relatively quiet. I love the bokeh it produces at wide aperture. In my opinion if you want a reasonably priced long telephoto zoom that produces very fine images, this lens is a great value. Images attached are from a recent pro bono shoot for the local Saint Bernard Rescue and was my first attempt with the lens.

    Rated 5 out of 5 by from Excellent lens and superb value Pros: - Sharp, good IQ - Excellent HSM AF. I've been able to track birds in flight easily. - Handholdable with very effective IS. The tripod mount makes it easy to hold the lens. - Easy to manouver and zoom with the zoom ring. - Heavy lens, but I've used it for hours on end and not regreted it. The not so good: - Heavy lens so there's sometimes a tendency to leave it at home. - 400mm wide open has slightly low contrast. Easily fixed in PP. - IS gives me 3 stops pretty comfortably. You need to be very steady for 4.

    Rated 4 out of 5 by from Excellent value brings sharp clear shots After weighing through the canon offerings in the store they were just too pricey for my wallet. The gentleman behind the counter recommended this lens to me. I wanted to shoot the F1 in Canada this year and considering it zooms to 400 coupled with a 40D this was the lens for me. During the weekend I found the weight took a day to get used to, but attaching to a mono-pod helped greatly. The shoots I took were very clear and sharp at the higher f numbers (8 and above), however, thats not to say that at the lower f stops it was not sharp just that it was better higher up. Fast zoom and good tracking (following an F1 car at 170mph is by no means easy). Love this lens and I have many excellent shots from that weekend. Now I just need to get out and use it more! The case that comes with it is very sturdy and a nice extra.

    Rated 5 out of 5 by from VERY NICE LENS This lens is actually better than I expected. The build quality is excellent. The AF is silent and faster than I expected, (yet slower than Canon, although still very usable) The OS is great when hand holding in low light. I own a T1i, I planned to boost my ISO greatly when shooting at night at the local park, but surprise, surprise, with the OS was enable, I was able to greatly reduce the ISO from 3200 to 1600 while shooting at 1/10 with great results. All in all I like this lens a little better than my buddies Canon 100-400mm. Mainly because I'm not a fan of its push-pull style, and its $1500 price tag. For half the money this lens is more than adequate.
