Most helpful customer reviews of 126 123 people found this review helpful. Sigma Nikon, but still useful by Zachary Wagner At this time, almost all the lenses I have a Sigma, the only exception is my Tamron 17-50 2.8 (which is a target, very, very strong). I have the Sigma 120-300 2.8 for a few days (the best goal I've used), Nikkor 70-200 VR and 2.8 had. The two were due to cost, I simply could not at that point are returned. I read the reviews for this business objective, and worried about buying, because they were not exactly glowing. Well, I'm here to tell you that are from what I read trade magazines for this lens is always perfect. It's good and bad, as someone who will read her. The good thing is that the autofocus has been stellar this goal. It is very fast and is at least as fast as the Nikkor. The zoom ring and focusing ring is smooth, and the goal seems to do very well, as all my other Sigma lenses. Not only the fast autofocus, it's still not as heavy, either, and I find it very convenient to use (compared to 120-300, this thing is light as a feather, and it weighed a lot better than the Nikkor) . I also think the goal of becoming strong enough to most of the zoom range, especially stopped down (as it is for most lenses, Nikon). Yes, I said almost the entire zoom range. The evil behind its ugly head at the end of the long zoom (which is a shame because there is very likely that a goal like this is to keep most of the time). At 200mm, this lens loses a lot of sharpness, while closing it helps a lot, simply should not be so bad. These pictures are useless? I will not say, and Photoshop can almost work miracles in most cases. But what is worse is the sharpness (or lack thereof) is the chromatic aberration. There is a lot. I think a lot of 200mm. It 'was the worst CA of any lens in my collection, hands down, and worst of all the goals that I used maybe this is due in part to the bold attempt to make a Sigma macro lens for it, and the really bad' On the other hand on it - the macro is not terrible either. It must also take into account that I use this lens on a Nikon D300, a DX sensor camera (small). Thus, the results may be different if you use a full frame. Eventually, I will keep this goal in a number of reasons. One is price. Third of the cost of the Nikkor lens, this lens is a serious reason and can not be forgiven a little '. The second is the auto focus. Wow it is fast. And precise. Since that will be used mainly for sports is very important to me. And strange as it may be, the other reason is the macro. Yes, it is not great, but I always have a lens with this zoom range that has macro capability. Apparently there are huge compromises to get there, but it is what it is I would have given it four stars, but because of the costs, but ultimately decided I was three, because if Sigma would like to play with the big boys a little better than they really this show. So in evaluating this lens, then ask yourself what your needs are as a photographer, and the benefits of this lens may be sufficient to outweigh the disadvantages. For me the answer is yes ... but you make up your own mind. 64 of 69 people found the following review helpful. Great lens ... not an inexpensive alternative to Nikon's By Jon David Schein I was afraid when I bouught this lens because I had just tried to copy the Tamron, but my only experience with non-Nikon Sigma. I love this lens. I have for shooting sports events for my university newspaper, and have no problems in the month I had. Autofocuses faster than the Tamron. A monopod is not necessary because it is a fast lens, even at night with the lighting of the stadium, the AF has some problems. The best I've heard of people want.
