The Sigma 18-200mm lens was designed for APS-C sensors and features a new matte black finish, thermally stable composite material in its construction and smaller and lighter design then previous models. With exceptional performance, this 18-200mm camera lens does not sacrifice image quality for versatility. Having the ability to shoot from wide angle to telephoto is highly useful particularly for travel photography, landscape photography, street photography, portrait photography and nature photography.
An improved minimum focusing distance of 14.7 inches paired with the use of Special Low Dispersion glass, the 18-200mm excels at bringing out great detail in close-up photography as well. A Hyper Sonic Motor (HSM) ensures quiet, accurate and fast autofocus and an optical Stabilizer (OS) helps compensate for camera shake. Make this lens your All-in-One lens to handle any shooting scenario.
I was pleasantly surprised at the build quality of this lens. We would all like to buy the best most expensive "L" glass from Canon, But I pick my battles, in other words I'll invest in a top end 180 macro or 100 macro, but The Sigma line is also a very smart alternative considering the price. I also have their 150-500 zoom and absolutely love it. This zoom is light, compact and has a huge focal length range. I try to use all my lenses in the "sweet spot". In this range the images with this lens are great.A relatively small investment for huge versatility.
A very good all around zoom if you can't lug around all your lenses. Appears well made. I have another 150-500 Sigma zoom that I love, This one is fast becoming a favorite. It is very compact for the zoom range. If you stick to the old adage to use the middle apertures of ANY lens, Your images will look great. A lot of bang for the buck. The only thing that could be better, if possible, is more travel in the manual focus ring. A very small movement greatly changes the focus. Not so handy when doing focus stacking. My real gripe is with Adorama's customer service. There was no lens hood in the box, and they acted like it was a criminal investigation. Long story short,after way too long, I got a hood from Sigma
Let me first say that 4 stars is for the product only.A fine lens for the money and the bonus of the bundle. The lens is compact and versatile. The first images I have taken are great. I plan to go out tomorrow and give it a real work-out.I bought this to avoid constantly changing lenses in the field. I know something is always given up with these extreme zooms, but If used properly Great images can be had. Now the bad part. This lens is supposed to include a hood. None was included. I immediately notified customer service and was told to provide pictures of the shipping box,manufacturers box and the product to indicate if there was any tampering or damage.They said these may be used in an "investigation". Really?! So I sent them six photos. Then I was told they notified the warehouse and would see if they could find the hood and would get back to me in two business days. Really?! I have ordered many,many items from Adorama with never a problem. COME ON I paid for this! Send me the hood! Sort out your problems on your own time.
I use the lens as my 'normal' lens; it's the one always on my Canon7D. Focus is sharp and the IS function works well. It's lighter than my old 10-200 with a filer size of 62mm vs 72mm. So far, I'm pleased with it (only used it for a month).
Very practical for travel, children and, in my case (I have two wide angles), using it as telephoto. The lens is very well built, but the focus ring is a little loose. Sharpness is pretty good if you stop down, but wide open could be better. See below two images (@100%): i) center (@200mm) and ii) extreme corner (@200mm).
I received the newly released "Sigma 18-200mm F3.5-6.3 DC OS HSM" lens a couple of days ago and my initial tests have been quite impressive! I have only had a chance to do a quick direct comparison of the Sigma 18-200mm lens to the "Canon ef-s 55-250mm f/4-5.6 is ii" lens that came with my Canon SL1 DSLR. So far, the Sigma zoom lens appears to be noticeably sharper than the Canon zoom lens. I also think that the Sigma rendered colors that are more vibrant and have better saturation. The Sigma focus is very quiet, fast, accurate and does not "hunt" as much as the Canon lens does in tough situations (like lots of detail and low light). The Canon zoom lens tends to hunt for focus on busy objects, such as berries on a tree. As a result, the Canon lens keeps trying to lock the focus and takes a longer time doing so. The Sigma locked focus easily and didn't "hunt" as often or as long. The Sigma lens is much heavier than the Canon, but that is to be expected since the Canon is mostly plastic. The Sigma lens has a solid quality feel. Lens weight is something that should be considered when deciding on purchasing any lens. One of my favorite test subjects is my solid gray cat. I like using him as a photo subject because of his dark coloring and fine details. The Sigma handled his coloring quite well with a perfect exposure that impressively detailed his slight color differences. Under the same indoor natural-light conditions, the Canon zoom did not capture his subtle color differences as well, and as a result, his color was more uniform and muted. Don't get me wrong, the Canon photos were still very good, but the Sigma photos were excellent. Fine detail such as whiskers and fur were razor sharp with the Sigma and slightly less sharp with the Canon. I also took a series of outdoor photos where the subject had lots of detail that included light and dark areas. Light/Dark edge transitions are commonly subject to a chromatic aberration known as "purple fringe". Photos taken using the Canon 18-250mm lens had very visible "purple fringe". The Sigma 18-200mm did not show any (at least not obvious) "purple fringe". The Sigma has lots of positives, but there are a couple annoyances so far. The first one is that the zoom ring is not as smooth as I would expect. It tends to bind a little bit between 80mm - 130mm. That might loosen up eventually, but I still plan on talking to Sigma about it. The other comment is that the Sigma lens feels kind of "rough" while being mounted on the camera. It almost feels like you are forcing the lens on the camera when twisting the barrel. The Canon lenses mount extremely smooth. This is not a big deal, especially since I will rarely be taking the lens off of the camera. Overall, the Sigma 18-200mm lens is a well-made, high quality and affordable all-purpose lens. Very impressed with it so far. I will post updates if there is anything significant to add to the review.
I had higher hopes for this lens. The Sigma 17-70 is in my bag and is leaps and bounds better than this lens. The clarity just isn't there and I have to push my ISO in order to get the image. If it's not too late, I'm returning this lens and will do more research and save my dollars to afford a quality lens.
Used it from graduation. Great for finding who you want to take pictures of.
the price was right, and since I like to keep it to one lens when I travel , this makes a lighter , less bulky package of my canon rebel, without losing much telephoto , etc.
This is my first non-canon lens. I am using it with T3i The Good - Solid build. Compact and Lightweight. Fast, accurate, and reasonably quite Auto Focus. Good IQ for the price. Zoom Range (29 - 320 for T3i) Outdoor closeups are great, it gives smooth background blur @200mm. The Bad - It creeps. It can be locked only at 18mm. Some stickiness in zoom mechanism at mid-range. F6.3 is a minor issue, It affects only if you are shooting in poor light with above 80mm zoom and Evaluative metering. Overall - Nice travel/walk-around lens.
