Description

Product description Sigma 18-200mm f/3.5-6.3 DC OS Zoom Super Wide Angle Lens for Nikon The Sigma 18-200mm high-zoom-ratio lens is designed exclusively for Nikon digital SLR cameras and is capable of covering a wide range of focal lengths, from wide-angle to telephoto. Two Special Low Dispersion (SLD) glass elements and two hybrid aspherical lenses correct for all types of aberrations, letting Sigma house the extended-range super-zoom lens in a compact and lightweight body that measures 70mm in diameter and 78.1mm long and weighs a mere 14.3 ounces. The new lens coating, meanwhile, reduces flare and ghost--a common problem shared by many digital cameras-- while also creating an optimum color balance. Other details include a minimum focusing distance of 45cm (17.7) at all focal lengths, a high zoom ratio of 11:1, and a maximum magnification of 1:4.4. The lens design incorporates an inner focusing system that prevents the front of the lens from rotating, making it particularly suitable for using circular polarizing filters and petal-shaped lens hoods. In addition, the overall length of the lens never changes during focusing, making the lens convenient to handle and easy to use. Finally, the lens's zoom lock switch eliminates "zoom creep" during transport --a convenient addition when traveling. The lens, which includes a metal mount, is backed by a one-year warranty.

  • Excellent solution for many Photographers.
Style: Nikon DSLR
This was shipped to my office yesterday, so I naturally had to play with it. I have an old Nikon D50, and had gotten use to the kit lens that was on it. This Sigma is CONSIDERABLY larger and heavier. I expected that of course, and maybe I'm just getting old, but IMO its a pretty hefty lens. I bought this lens expressly for the Optical Stabilization, so that was the first thing I tested. My office has a logo painted on the far side, so I handheld, indoors, at 200mm and focused on one letter. The lens setting was f6.3 at 1/30 sec. Looking side by side at the OS and non-OS shot in the camera lcd screen, they looked almost identical. However, puting them in Photoshop and blowing them up revealed a whole other story. The non-os picture was blurred - and no amount of sharpening in Photoshop could correct it. The OS picture was sharp. I'm not easily impressed, but I was really surprised at how well it worked. When I enlarged it to 200 percent in Photoshop, it seemed to be a bit soft, so I applied a small bit of sharpening from the software - and ended up with a photo that looked like it had been shot with a macro lens from 3 feet away on a tripod. It was outstanding. I bought this lens for 2 reasons. First I am a Realtor. All of my listings need indoor shots, and I stay away from flash if I can - natural light seems to create warm home interiors. Problem was, most of these shots ended up in the 1/8-1/15 range - so I packed a tripod around. This lens should be far more convenient. Second, I am a photographer. I shoot a lot of weddings and reunions, and I often try to drag the shutter, especially in churches or large halls, where I want some ambient light to fill in the background. This lens will allow me to shoot all day at 1/15 sec. with a TTL flash, and create some nice balanced portraits without the background blur found in most of these sort of images from the slow shutter speed. I have read in other reviews that this lens is slow. It is. If it were a straight lens with f6.3 at 200 mm, I wouldn't even consider it. However, the OS allows you to handhold safely at least another 2 fstops slower, so IMO, that makes up for the slow speed of the lens. Besides, it's ridiculous to compare a $500 lens to a $1700 lens in the first place. The lens also has a bit of distortion. If you primarily shoot architecture, and don't want to correct all of your images, this isn't the lens for you. I haven't noticed any lens creep yet, the zoom ring is pretty stiff, but that may change over time, and there is a lock, anyway. One major complaint I have about this lens: the focus ring is prominent, and easy to grab. TOO easy to grab. Sigma warns against turning the focus ring when you are in autofocus mode, for fear of damaging the lens. I trained myself after about 15 minutes to keep my hand off of it, but I noticed that anyone that picked up the camera had a tendency to want to turn the focus ring, thinking it was the zoom ring. If you hand this lens to someone to take your picture, be sure to instruct them how to handle it, or risk damage to the lens. The focus mechanism and OS are a bit noisy, but mostly because my ear is about 4 inches from the camera when it operates. I care very little about the noise factor. Overall, this is a great lens. Inexpensive, will probably be on your camera exclusively, and allows you to handhold the camera in low light situations. I never got to test it against Nikon's version, but the difference in price made the choice easy. I recommend this lens highly. ... show more

  • Good lens for the money
Style: Nikon DSLR
I buy many products based upon reviews from other users. That is also the case with this lens. I bought my Nikon D40 about 3 months ago (after 10 years of using point and shoots, including my treasured Canon S2is super zoom), with the kit 18-55mm lens, plus I bought a Nikon 55-200mm VR lens. I love the VR lens, but traveling through Europe for 2 1/2 weeks proved to me that I HATE changing lenses. It's inconvenient and potentially contaminates the inside of the camera body. So, I started looking around at something that I could use as a single walk-around lens. I love the wide angle perspective of the 18mm end, plus needed at least 200mm for the telephoto end. I liked the idea of Tamron's 18-250mm, but it's not image stabilized, which is really essential at the telephoto end. So, back to the Sigma. I read Camera Labs review of the non-stabilized Sigma 18-200mm, and it was favorable. So, I figured that the new stabilized version would be at least as good, and probably better. I have not used this lens much over the past couple of weeks, but have found that (with a couple of exceptions), it focuses at least as quickly as the 18-55mm Nikkor kit lens, if not faster. The OS works great, making hand-held photos rock solid at 200mm. The only thing that I haven't spent a lot of time doing is taking indoor photos with it. I have taken indoor photos with the onboard flash, and they seem to work fine. I have not had much luck getting sharp photos at the telephoto end indoors, but admittedly have not tried very hard. I'll update this later, as I get more experience. Based upon what I know now, I am NOT AT ALL SORRY that I bought this lens. I was really having a hard time choosing between this and the [MUCH more expensive] Nikkor 18-200mm, but this lens seems like it is well worth the money spent. The focus/OS noise does not bother me at all (In fact, it's reassuring to hear that the camera is trying to focus, etc...). The only thing I wish Sigma had done was to make the lens Auto/Manual focus without having to move the switch from Auto to Manual, which the Nikkor can do. However, if it auto-focuses reliably, I guess it won't be a big deal. The zoom ring is a little tight right now, but I imagine that it will loosen up over time (hopefully not to the point of requiring the lock to be engaged). I also like the large manual focus ring; the Nikkor's is much smaller. Don't be put off by the 72mm diameter (which I was initially). It's not a big deal. Yes, it is quite a bit heavier and larger than the kit lens (or even my 55-200mm Nikkor), but not overly so. In fact, it makes the camera easier to hold, since I think the D40/40x/60 grip is just a little too small. I was concerned that the onboard flash will be blocked by the lens, but it seems to have no effect. I'm not seeing any shadowing. I'll keep you advised on how my ongoing review is going. Happy shooting! Update: Sept 19, 2008 - I continue to love this lens. The ONLY thing that bothers me about it is (as someone mentioned in another review) that the zoom and focus rings are too close together. When I hand this to my wife or son, I have to remind them which one is the zoom ring, and not to touch the focus (BTW - It makes a gears-are-grinding noise when you move the focus ring without moving it to manual - Not good, although it does not seem to have hurt the lens). There is a slight amount of shadowing the on board flash when you are at any zoom over the 18mm. However, I rarely if ever use the on board flash. I have a Nikon SB-400 flash that is absolutely essential inside, where you can bounce it (read Ken Rockwell's review at [...] I have not put the 18-55mm kit lens back on this camera since I have had the 18-200, and probably won't. I have a very old Nikon G model 50mm f1.8 that I can use (no metering or autofocus) on those low-light non-flash indoor shots, where the Sigma is not at it's best (although it's still very good). ... show more

  • Upgrade rating to 4.25 (Original review title: 3.5 would be more accurate)
Style: Nikon DSLR
I have had this lens since 9 July 2008, and used it without incident until 25 July, when the OS failed. Up to that point, I would have given this lens a five-star rating without the slightest hesitation. The distortion control, as well as the sharpness on the first sample were excellent. Furthermore, the focus was accurate to a T in all situations, including very low light. The replacement lens, which I have now used for about a week, does not have nearly the same sharpness at the edges. It is fine in very bright light, but in dimmer situations, both the sharpness, and the focussing ability, are not up to the standard of the first sample. I also find that the OS on this sample does not give the same f-stop compensation as on the first one. This said, the lens remains a good one, and I would still recommend it for use with the Nikon D40. Whether or not I will retain this one, or again request a replacement based on the less than stellar focussing ability in low light/low contrast situations remains to be seen. UPDATED 9 September 2009 I did replace the lens a second time -- under the 30 day exchange policy of Amazon. The replacement was, and is, considerably more like the first one -- with generally fine, fast and accurate focus across the range. There is a slight amount of softness, on the right-hand side. I now use this lens with a D90, as well as with the older D40, and the upgrade in camera does not in any way reveal any additional flaws in the lens. I continue to recommend this lens -- provided the sample received is a good one. ... show more

  • Great All In One
Style: Nikon DSLR
I am not a pro but sure have more confidence with this lense. I used it to replace a non-VR 70-300. I love it! You have read other reviews and specs that note that this is a heavy lense. Guess what? It is - so don't buy it then trash it because of such - it also is round :). I rolled the dice in a decision over this or the Nikon. The money was just right and I am super glad of my decision. The first big shoot was bridal portrait. We were very pleased with the results (especially compared to overall pics from the non-vr replaced). We shot around 400 pix, and I was exhausted at the end from holding the camera, lense and SB600 flash unit). The setup is heavy but I think I like the feel better than lighter (feeling cheaper). It also comes with the option of extending the warranty (paperwork was in my lense box). So, while not a perfect fit for anyone, if you are a newbie like me just happy to have something that is at lest "close" to a real camera (working with a D40x) this is a good route. Cheers! ... show more

  • Sigma AF 18-200mm f/3.5-6.3 DC OS Zoom Lens for Nikon D40
Style: Nikon DSLR
UPDATE: This lens ceased functioning 14 months after I bought it. The local repair shop could not fix it, and said it needed to go back to Sigma. Minimum repair price was $125, and likely higher than $150. Plus shipping. I changed my rating from 4 stars to 1 star because of this. I replaced it with a Nikon 28-200 that has been quite satisfactory, though I occasionally miss the extra wide reach of the Sigma. Call me an unhappy Sigma customer. ORIGINAL REVIEW: I have used this lens with my D40 for about a month. I was concerned about the relative slowness of the lens, especially at full zoom, but the OS makes up for it allowing me to shoot successfully at slower shutter speeds. Optically the lens seems fine to me. It DOES autofocus with the D40. Combined with a Sigma 30mm HSM prime lens, I have everything I need for most situations. This lens is significantly larger and heavier than the Nikon kit lenses. You will know that you have this 1-lb lens hanging around your neck! I am very satisfied with this lens. Recommended to replace both the 18-55 and 55-200 Nikon kit lenses. ... show more

  • Very pleased indeed, after having some doubts after reading reviews.
Style: Nikon DSLR
I agonized over the decision about whether to buy the Sigma AF 18-200 DC OS. The on-line sites (such as dp) showed softness at the edges, particularly with the f-stop wide open. There were criticisms about the focus ring being easy to confuse with the zoom ring. There were complaints that the optical stabilization isn't state of the art. I bought it anyway because I was looking for a super zoom that could do wide angle, but also go all the way to decent telephoto in a single lens and offered optical stabilization so those telephoto lengths would be usable hand held and couldn't afford Nikon's offering in this focal length range. I have been tremendously impressed with the Sigma AF 18-200 DC OS. The optical stabilization is quite dramatically noticeable and makes a big difference. Low light shots in the 18-55mm range that I would never have got away with with my kit lens are distinctly do-able with the Sigma - despite it's extra bulk. Telephoto shots in indoor lighting situations are fine too. Subjective sharpness is fine. The softness the reviewers note in the corners isn't subjectively noticeable in the pictures my Nikon D50 is taking - at the screen resolutions I'm viewing (and posting). Color saturation and contrast appear superior to the Nikon 18-55 kit lens I'm replacing - and subjective sharpness is at least as good. I was worried that the bigger Sigma would be a big adjustment. It's definitely bigger than the 18-55 kit lens - but it's not a big adjustment. I had to get a bigger case and I added a hand strap: (the inexpensive and very usable Opteka Professional Wrist Grip Strap for Digital & Film SLR Cameras). I'm quite happy with how this rig handles. So why only 4 stars? I dock a star for the focus ring issue (the focus ring is a bit prominent and has a very similar looking and feeling grip to the zoom ring). I wish the focus ring had a more clear tactile demarcation (maybe a diamond pattern, instead of the same kind of ridges the zoom ring has - for immediate tactile recognition). As it goes I usually stow the lens hood backwards for storage and this overlays most of the focus ring - forcing me to grab the zoom ring. I also dock some because it has some issues acquiring focus at longer focal lengths in low light. This is a bit of a quibble because the kit lens also has issues acquiring focus in low light, but the situation is a bit worse with the Sigma zoomed out. All in all I'd give close to 4.5 stars given my general level of satisfaction. The Sigma AF 18-200 DC OS ultimately does everything I wanted. It provides a single lens solution to the vast majority of shooting situations. It provides very acceptable image quality. It provides usable image stabilization and decent ergonomics which make it usable in a wide range of circumstances. Bottom line, this lens turns my camera into a much more powerful tool. I wonder why I waited so long? ... show more

  • Lens faults
Style: Nikon DSLR
I purchased this lens to attach to a Nikon D-60 SLR camera. It was to be used in my many excursions with a travel/exchange group. This year we went to Turkey. At first I was satisfied with the lens but it commenced to give me camera errors that read sort of," Lens not fully attached to camera". To correct I locked the lens and tightened. This happened approximately 15-20 times in an eighteen day period. Also, the lens developed numerous spots. In handlind the lens while on the camera I either put the lenscap back on, or cupped my hand over the lens to prevent burning, and was in a very dry area. I would try another one in the future if I can be assured the manufacturing and quality assurance has improved. I am NOT an expert in lens quality, but believe this particular lens is and was faulty. ... show more

  • If You Have a Nikon DSLR You Need This Lens!

This lens from Sigma is, in my humble opinion, the BEST investment the owner of a Nikon DSLR can make on a limited budget. The auto-focus feature is very fast, accurate, and convenient. The zoom range covers just about all the possible settings and situations an amateur or semi-professional photographer will ever encounter. I had been using a Cosina 70-300mm zoom lens (without auto-focus) and a Tamron 28-80mm (without auto-focus) for several years...waiting for the right lens to come along. Well, that time is now and I'm very happy with this lens' performance. My other lenses are going to be gathering dust very shortly. If you can find one for approximately the same price as I paid ($200) or les...GRAB IT! ... show more
