SIGMA's own unique OS (Optical Stabilizer) technology
This lens is equipped with Sigma's own unique OS (Optical Stabilizer) function. This system offers the use of shutter speeds approximately 4 stops slower than would otherwise be possible. It makes telephoto shooting easy for many types of photography such as sport and nature. For Sony and Pentax mount, the built-in OS function of this lens can be used even if the camera body is equipped with an anti-shake function. As compensation for camera shake is visible in the view finder, the photographer can easily check for accurate focus and ensure there is no subject movement.
* For Pentax and Sony mount, it is not possible to use AF and stabilizer function (OS) when attaching to film SLR, Pentax ist* series and K100D DSLR cameras.

I couldn't believe the price for this lens. I've used Signma lenses before and I thought they were as good as other lneses. the price was right, I purchased this lens to go with my new Nikon D7100. I was disappointed, the pictures didn't have the crispness I was hoping for. the same lense by Nikon cost 3X more. I am returning this lens and already have purchased the Nikon lens. It's a transformative experience. You get what you pay for. there is no magic feather balancing quality and price. Don't get me wrong, the Sigma was everything I could expect of a lens that costs 1/3rd the manufacturers standard product. On a related note, don't get too good a lens as now every picture I've previously taken is a pale comparison to quality pictures I'm getting with the manufacturers lens.
I do mostly nature photography. This lens along side similar lenses performs well and the price is well below what I have paid for my Nikkor lenses. It is light, quick and appears to be sharp on the computer screen. I have not made any large prints yet.
I mainly use this to shoot local birds and small critters with the use of the macro/telephoto function. This lens is very sharp. It's actually sharper than my kit 18-55mm lens that came on my D3100. The lens is a little soft at 4-5.6, but gets really sharp at f8. The lens has some weight to it and it feels pretty solid. The macro function works between 200-300mm and still produces sharp results! I am extremely happy with this lens. So sharpness, contrast, and its macro function are all positive. It's a very good lens. Now, the only thing that I am not too fond of is the focusing time. If you're using auto focus, the motor takes awhile to focus, but it gets the job done. The motor itself is a little loud. Other than that, it's a really good lens for its price and I highly recommend it to others looking for a great telephoto/macro lens at a bargain price.
This is the second of this particular lens I have purchased, and for the price it is certainly worth it. After I dropped my lens, I had considered several others that were considerably more expensive and faster, but after careful consideration I chose to got with this lens, considering all the great photos I got with my previous lens. The optics are good throughout the range, and the close focusing capabilities are one of the major reasons I love this lens. I do confess, the major drawback is the noise, and it is not particularly fast, but for shooting from a distance it should not present a problem.
used it on to take pictures of a barn a 1/4 of a mile away. did a great job. barn edges were straight, very clear, weight don't even notice. Keeps up great with moving trains.
Professional photographer taking flora and fauna. Sometimes use with a 1-4 teleconverter and lens works well in AF with it
This is fantastic value for an entry level zoom lens. I use it on my Nikon D3100. Yes, the auto focus is a little slow, and it is a bit noisy however I can not be happier with this purchase. I wanted a telephoto lense, since I only have the 18-55mm kit lens the D3100 came with. After reading review after review, I pulled the trigger on this one, and happy that I did.
This Sigma lens is well built and feel solid. I am impressed by its quality considering the price I paid for it. The auto-focus is noisy and slow, but it gets the job done. Macro is down to 1:2 @300mm, very useful for taking macro pix of flowers, gritters and pets. You have a 3+ feet working distance. With the 9-blade diaphragm aperture construction, it makes a fine portrait lens with pleasing Bokeh. However, I would not recommend it for Sports or Hyperactive kids.

Using this lens all the time with the 18-55mm one. Takes great photos and the price is affordable. Although, it doesn't come with VR.
