Sigma 18-200mm f/3.5-6.3 AF DC Lens for all Nikon DSLR Cameras

I have read several of reviews for this lens, many are favorable and some not so favorable. I purchased this lens for the same reasons many others have, to have one lens to carry around. This lens is fantastic. I don't understand why some say the lens is no good. I have had no problems with anything. It seems that most of the favorable reviews are from amateur/hobbyist photographers and the not so favorable reviews are from so called "professional photographers" I fall into the amateur/hobbyist category. They throw around buzz words like chromatic fringing, vignetting, lens creep, soft corners, and image stabilization; I guess trying to impress someone. After goggling some of these words to find out more I have not experienced any of those things. What I don't understand is when they say stuff like "the lens has noisy autofocus" are you taking pictures of something or someone that you don't want them to know? I bet they are the ones that call a tire manufacture to complain about the road noise their tires makes while driving. Another is "No image stabilization" I do believe that the description is pretty clear that this lens does not have it. "Doesn't do well in low light and blur if you don't use a high shutter speed and hold it steady". Well duh! Again the description is pretty clear f/3.5-6.3 if you shoot everything in low light this may not be the lens for you. And you may want to invest in a tripod. I am no professional by any means but I do know how to operate my camera and how to adjust for low light conditions and how to avoid image blur at slow shutter speeds and how to focus the camera manually. So I wonder if they are really professionals or self proclaimed professionals! So many people have given in to the big marketing schemes by the manufactures. Just because something cost more does not mean it is any better you are paying for their big marketing budgets not a better product. For the most part all cameras will produce the same results. The only ways a manufacture can really improve on a DSLR and continue to sell them is up the megapixels and add HD video capability to the cameras. Don't know about you but I think they force the consumer to have that feature on their DSLR so they can charge more. I am a Photographer not a Cinematographer it is a function that I will never use but had to pay for. I have a friend that purchased one of the big name cameras with 21MP he has no plans for printing billboard signs and bought it because the sales person said it was what he needed if he wanted be taken seriously as a photographer; obviously my friend has more money than sense. I don't see any difference in picture quality with my $500 Pentax at 6MP besides the file size which took a week to ten days to download...

I purchased this lens thinking it was a good value, and I got disappointed when the lens completely failed in the middle of a trip after getting the famous error message. Since I was within the 30 days purchase, I got it replaced by Amazon. The replacement started failing this morning... same error. I did some research, and apparently 30-40% of this particular sigma lens are lemons (google it!!). Unfortunately, this happens after taken about 200 shoots..... if you are beyond 30 days of purchase when the lens start failing AMAZON DOES NOT REPLACE THE DEFECTIVE PRODUCT, despite the one-year warranty. Sigma customer center sucks, and they make you pay for a secure back and forth shipment. I STRONGLY recommend this product. The price is very attractive, and you might find the lens you get is a not a lemon (btw, the lens takes wonderful pics!!).... if you wanna give it a try... i would recommend NOT TO GET IT IN AMAZON, but in a local store you can return the lens within the one-year warranty offered by the manufacturer.... AMAZON told me I have to eat mine now....

After taking long and hard look on Nikon D5000 and its "kit lens" 18-55mm zoom lens, I was convinced that I needed something more powerful to have it on as daily lens and avoiding having to swab out lens frequently, or worse, in between crucial moments when you should be busy composing and taking shots of objects from multiple distance. Naturally, Nikon 18-200mm was the first choice, but after seeing rather substantial price difference, I decided to take up on dpreview's review on this lens (overall verdict was very similar to Nikon's) and save money (1/2 price compared to Nikon) and use that towards other goodies (Flashlight, prime lens). I spent 18 months taking pictures using this lens as my every day lens, almost 8000 shots and I can confidently say that this type of super zoom lens should be what everyone should own as their starter lens. I am sure professionals would own multiple lens and something far more expensive for their needs, but for everyday Joes, hobbyist and novice, this is more than anyone can ask for. It is by no means Macro lens and I have run into times where I would have to step back in order to take shot (I was too close to the object), but you can easily compensate that with zoom. Image can be soft at certain distance, but it is mostly non-issue unless you are scrutinizing it carefully. Built-in pop-up flashlight on camera will be an issue as it protrudes too far and will cast shadow. Using external flashlight is highly recommended, but being creative with other settings to avoid using flashlight will be fine. It is a fine performer in places with ample lights, and saves many shots in darker environment with built-in OS function. AF can be bit slow at times and sometimes lost track of what it is focusing and end up focusing on wrong object, but you can easily override that. As many other super zoom lenses, it does create distortion in different levels (due to limitation of design), but with programs such as Lightroom, you can correct distortion as well as chromatic aberration. Added bonus of using this type of super zoom lens is that you can use it as passable wide angle lens (18mm, 24mm on Nikon DX camera) and cover more area. As a DSLR newbie, I was shocked at how heavy whole camera was with this lens on it, but now, it feels more of that reassuring heft than anything else. Happy snapping! You won't regret this as your first lens.

元々は5年前にNikon D40用に購入したものです。 D40の標準レンズセットしか購入しなかった為に、100mm以上のズームレンズを探していました。 運良く70〜300mmレンズは手頃な値段で入手する事が出来ましたが、標準レンズとズームレンズの 間辺りで撮りたい状況に遭遇する事が多くなり、標準レンズの領域からズームレンズまで一本で カバーできるものはないかと探しておりました。 2万ちょっと程で、このレンズが売られているのを知り、購入いたしました。 D40は特に本体側にAF用のモーターを搭載していないので、AFモーター付きであるこのレンズは もってこいでした。風景写真から電車・飛行機・バスの写真、野鳥や植物（花）まで綺麗に写してくれます。 その後、D7000も購入しました。D7000は本体にAF用モーターが搭載されているので、このレンズに こだわる事はないのですが、使い慣れているという点から、どうしてもこのレンズを装着して 撮りに行くことが多いですね。 D7000用には後にTAMRONのAF18-200mm F3.5-6.3 XR DiIIを購入しました。性能的にはさほど大差はないと 思いますが、コンパクトさでいいますとこちらの方に利があると思います。 値段の割にはとっても良い性能の製品だと思います。

I purchased this lense after much deliberation against the much much higher priced comparative . Although I had several farcical events starting with the wrong lense being sent which made me think I was not meant to have it, however these things happen and the seller was positive and re-acted honestly to get things sorted out. I eventualy received the correct lense and put it straight into work whilst Iam no expert I must have taken and viewed over 50 or more photos with the lense over the first weekend I used it .It has a nice feel and looks the part on the camera it looks clean and sharp and in no way looks anything other than a quality lense from the out side.Fits well to the hand and the controls work cleanly and smoothly Pictures I took varied from the family groups,portaits of the kids Wife and dog including close ups and wider views. I printed some of these out on A4 size paper the results in my opinion as good as those in reviews of other named lenses that Ive seen when going from site to site and certainly good quality. When attempting to use the lense as a macro / close type photos of flowers ,rocks,and insects I had simlar pleasing results. The camera needs good light and sometimes needs a bit of fidling in low light conditions I put this down to the size of the lense but when using only the built in flash again the pictures are of good quality. I was warned of the failing of lense creep with such lenses but I can say not once have I experienced any at all either using the camera pointed downwards or upwards for long periods All in All I have not to date been disapointed with the results and since I didnt have to pay twice as much any niggles with it seem acceptable If your dwelling on this lense for the money at the moment I cant fault it and probaly in the hands of a more proficient camera person the results obtained would be even better Iam I pleased I bought it most certainly yes

Es un objetivo de buena calidad con que se pueden hacer buenas fotografías. Da mucho juego en fotografía a buen precio.

SIGMA18-200㎜は古い(☆－1)が、PENTAX 12-135㎜と大きさは変わらず、PENTAX 12-135㎜より軽いし画はシャープ。 販売者記載の文面をよく読めば、中古でも良い品に逢える。 正に今回のレンズは大当たりの美品。 このレンズ特徴は『絞り』。 絞り開放から２つ絞るのが妥当な設定。 私としては、広角から50㎜くらいをF5.6。50から200㎜をF8と一応考え使えば、オールラウンダー的に良いと思う。

ottimo per nickon per le solo foto per il video non mette ha fuoco del resto tutto ok alla prossima
