This telephoto zoom lens incorporates Sigma's original OS (Optical Stabilizer) function. It offers the use of shutter speeds approximately 4 stops slower. Three SLD (Special Low Dispersion) glass elements provide excellent correction for chromatic aberration. This lens is equipped with the rear focus system that minimizes fluctuation of aberration caused by focusing. It provides optimum image quality throughout the entire zoom range.
The super multi-layer coating reduces flare and ghosting. High image quality is assured throughout the entire zoom range. The minimum focusing distance of 150cm (59.1") throughout the entire zoomrange and has a maximum magnification of 1:4.2 make it useful for close-up photography.
This lens incorporates HSM (Hyper Sonic Motor), which ensures a quiet and high-speed AF as well as full-time manual focusing capability. The addition of the optical 1.4x EXDG APO or 2x EX DG APO Tele Converters produce a 168-560mm F6.3-8 MF ultra-telephoto zoom lens or a 240-800mm F9-11 MF ultra-telephoto zoom lens respectively.

I like my new lens !
I bought this lens 3 weeks ago and it is a incredible lens for the price. I made some comparisons shots between my Canon 70-200mm F4 and it is comparable image quality. The OS work very well and images are sharp even at 400mm at F5.6. I definitely recommend this lens to all action/sports and birds pictures. I am sure the 150-500 have same image quality. Go buy it. (I was looking for Tamron 200-500, Canon 100-400, Tokina 80-400)

I use this lens to get in closer to birds, frogs and dragonflies. For an Adorama rating of E+ the lens is like new. You can always count on Adorama's honesty.
I've been seesawing between the new Nikon 80-400mm and this Sigma 120-400mm all summer. I finally decided to try the Sigma. When it arrived I was pleasantly surprised at the build quality. So I put it to work out my back deck which faces our lake. I get lots of birds, butterflies and wildlife of all kinds and I was looking for an improvement over my Nikon kit lens 18-200mm. It's been two weeks of shooting and it is meeting my needs handsomely. Auto focus works fine with my Nikon D300 and the image stabilization enables great hand held shots even at 400mm. Photo clarity is very good. It does, like all these 4.5 lens' need good light. I love the Bokeh. The new Nikon may indeed be better but at three times the price, this Sigma is a great value.
This is my first Sigma Lens. I will try not to compare but give honest feedback. It was purchased for wildlife and has the necessary reach I needed to add to my bag. The lens is heavy, not a walk around but this was known. The weight is well balanced when mounted on a tripod. Images are sharp in the 120-200 range and soften some at 400mm. After shooting in the shade and direct sun where I received the better images I state the obvious; more light or proper light is best. Low light situations are not a strong point. I will test more in low light but for now more light is best for this lens. I'm use to f2.8 lenses. I did get better sharpness on manual focus when zooming to 400mm. That's not a bad thing. For photographers that understand equipment limitations and how to make adjustments you will be happy this lens is in your bag. Great price point!
I've used this lens on many occasions in different conditions and the results have been excellent. Being a photo enthusiast and not a pro I can't compare to the upper end lenses but I can say that in my opinion this lens is worth every penny and I am very pleased with it. I have needed little or no tuning with DPP and though it is made for a full sized sensor this lens works great on my Canon 60D. Shot everything from wildlife to baseball games to the sailboats in the Luis Vuitton Challenge Cup series.
I like to do landscapes along with some sports and animal pictures. This one has the reach I wanted in a zoom lens. Haven't had alot of time to try it out due to the bad weather lately but the test photos I've taken have been very good. It's not a light weight lens but then again what is with this kind of reach?
I read many reviews before I purchased this lens, many said the focus isn't good, I disagree! I think the focus is right on, and if you are running your speed and f stop correctly, you should have a great sharp photo ... great for the price
I like it, I read many reviews that the focus degenerates as you get to the 400mm length, I find that only if I don't have enough light and have to decrease my Fstop... I think it has great focus capacity, specially at 360mm...
Like tying two bricks to your camera, but it is balanced well for tripod use. The OS does allow hand held, but it seems to take a second or two to stabilize. If you get in a hurry, you can get blurry shots. The autofocus is pretty fast. The manual focus ring seems to be set too far behind the balance point so if you're handholding, it is kind of awkward. Overall, I'm pleased with the lens however.
I am a travel photographer of a state tourism office and really need a 400mm that's portable. This lens fits the need very well. It's less than a grand too.
Before purchasing this lens, I read many reviews comparing this lens to the Canon 100-400. I decided on this even though it's heavier, but I prefer the twist motion to adjust focal length. It's also $400 less. I only made a dozen test shots so far. The outdoor ones are very sharp at f5.6 and f16 ranging from 120 to 400mm. One indoor portrait isn't sharp, but the shutter is at 1/15 sec on a monopod! My experience with this lens is very limited. This review needs to be updated when I made more images. So far I'm happy with it and would highly recommend to those sitting on a fence.
