    Strengths:    • Solid build quality & finish, surprisingly good focus speed and accuracy.
    • Overall pretty decent optical performance, except at the very long end (in my sample).
    • Pretty unobtrusive internal focus, no rotating front-end. You can use petal shaped lens hoods, polarizers and grad filters without problems.
    • Quite heavy, especially compared to the D40’s (very good) 18-55 mm. AF-S plastic kit-lens. But, compact enough to be well balanced and not overly heavy - it is the lightest among its peers; you can use it hand-held and without penalty down to 1/125 or even 1/60 sec..
    • Very flare resistant. I have not seen any in my 4.000 takes with this lens, sofar.
    • Well placed AF-MF switch, useful creep-lock button for transport.

    Weaknesses:    • Chromatic aberration and purple fringing on highlight edges throughout the focal range, especially wide open. This can, however, be easily corrected in post or even in-camera (select Nikon models).
    • Pronounced barrel distortions at the wide end, some pin cushion in the medium to long focal ranges.
    • No built-in image stabilization. Users who are prepared to pay for an expected 1-2 stop gain, might want to consider the optically stabilized OS-version. (MSRP: $ 750)
    Combined with one of the clean high ISO Nikons, however, one ought to very carefully balance his options. You can get as much as 3 stops (ISO 1.600) from these cameras with minimal sacrifice, while 300 bucks extra is 300 bucks you can spend elsewhere.
    • Can *not* be used with the Sigma EX 1.4x and 2x tele-converters. But then, I would not recommend using a lens of this level with a TC, anyway.
    • The f/max. of f/6.3 at the long end is pushing towards the very extremes of AF capability; the lens may hunt on occasion, but only at the long end.
    • Not exactly cheap for a "consumer" or kit lens.

    Optical quality: 3,5
    Build quality: 4
    Design: 5 (no mayor flaws)
    Value for money: 3,5

    * 1 = poor, 5 = excellent

    Recommended (for social events, weddings, light travel, pseudo P&S)

    Bottom Line:   
    For starters, anybody who expects stellar optical performance from a 11,1 zoom, better stop reading right now. It is not going to happen, not with this one, nor with the Nikkor.
    I got this lens in a hurry, because I needed an all-purpose lens to cover a spur-of-the-moment client event. At the time, this was the only 18-200 mm. available in Santiago.
    I also took a look at the (now discontinued) 18-125 mm. f/3.5-5.6D Sigma, but decided against it because it lacked the built-in focus motor necessary on the Nikon D40, my target camera.

    Tamron offers a similar lens, and so does Nikon: the AF-S DX VR Zoom-NIKKOR 18-200mm f/3.5-5.6G IF-ED comes with optical stabilization (VR in Nikon speak) and a built-in Silent Wave Motor (the S in AF-S), which presently streets for about $ 700 at Amazon.

    I expected this Sigma to focus slow compared to my HSM and AF-S lenses, but it’s surprisingly fast on the D40, the only camera I’m using it on.
    Build quality is also unexpectedly good, with a metal (instead of plastic) F-Mount, a partially metal body and a nice - EX type - crinkle finish.

    The AF/MF switch is placed where I need it to be, and the lens also includes an anti-creep button that locks it in the 18 mm. position for trouble-free transport.
    Thanks to internal focus (IF) the front end does not rotate, facilitating the use of a petal-shaped lens hood (included), polarizers and other orientation sensitive filters such as grads; however, it extends considerably - making it look a bit “amateur” at the long focal end.

    At 18 mm., this lens suffers from pronounced barrel distortion and vignetting (wide open), but produces very good to excellent center sharpness, combined with good sharpness at the extremes.
    At 35 - 85 mm., the center is still very good, but the borders suffer at large (if you can call f/5.6-6.3 "large") apertures.
    However, stop down just a little, and border quality reaches again very respectable levels.
    From 100 mm. on, the lens is pretty good stopped down to f/8, but interestingly, testers found that resolution (MTF) starts dropping off as soon as f/11.
    You’d want to be extremely carefull with your aperture selection to get optimal results.

    I have found myself avoiding the 200 mm. end, where my sample is decidedly soft, even stopped down. Lay off a little, though – to 150-180 mm. – and the problem is gone.
    Because of it’s rather complicated optical construction, this lens suffers (as expected) from moderate chromatic aberration throughout it’s focal range.
    On the other hand, it’s not as bad as other, even more expensive, lenses of comparable focal range.
    In short, pretty decent for a budget 11,1 times zoom, which seems to reach its sweet-spot early on: only 1 to 1,5 stops down from its f/max. throughout the entire focal range.

    People who have been destroying this lens (and others like it) in their critiques, seem to forget that for some purposes - like social events, weddings and general light travel - an all-purpose 11x 400-dollar-zoom-lens comes in extremely handy, and therefore, ought to be forgiven for some of its weaker points.
    Lest of course, you are prepared to lose *the* shot while changing lenses back and forth (which I am not) or are planning to mount it on a 8.000 dollar D3x, which is plain out stupid.
    Lets face it, this Sigma makes for a fairly campact & light package, which, combined with any half decent DSLR blows the pants (plus underwear) off of any 10x zoom P&S camera out there.

    Strengths:    Small size - Large Zoom Range
    Zoom Lock
    Hood included

    Weaknesses:    Slow noisy AF
    Serious vignetting
    Only acceptable sharpness
    Poor exterior finish

    Bottom Line:   
    I bought this lens originally for my Rebel XT to replace the Canon 28-135 IS That I found did not offer enough wide angle with the 1.6 crop. While I was happy to get some wide angles I have grown to dislike this lens. First this has been the walk around lens for the Rebel XT and then in the last 8 months the wife's XTi. It's biggest issue is it shows serious vignetting. EVERY PICTURE with a light or sky background needs to be edited in Camera RAW to correct this. I would replace it but the large zoom range that it provides means that the wife can carry it in a small lowepro bag and not swap lenses, a task she hates. The finishing material has recently started to rub off. I would not buy this lens again. Canons EF-S 17-85 is a much faster focusing, quieter lens with IS for not too much more(in DSLR terms). It also has less vinetting. Heck, I think the kit lens may be a better option.

    Strengths:    Produces clear bright images, with faster more accurate focusing than the Tamron. (Price).

    Weaknesses:    This lens has less weaknesses than any other lens in it's price range.

    Some barrel distortion, and corner softness. It can have a hard time focusing in low light.

    Bottom Line:   
    I've used two 18-200mm lenses on my Nikon D50. The first lens I used was the Tamron. It had to much distortion, and softness for my taste.

    The Sigma's 18-200mm produces sharp clear center images, with faster more accurate focusing times, (compared to the Tamron), with less center distortion. However the lens does produce some barrel distortion and corner softness.

    Remember this is not a high end lens, but for the money I think it is a very good lens for me, and it's intended market.

    Strengths:    Light, easy to walk around with.

    Weaknesses:    autofocus has problems with little light situations

    Bottom Line:   
    The Lens is okay, but I don't know if it's a coincidence or not. Because I live in a dusty country it's annoying. Once the lens is on my camera, I believe somehow a lot of dust gets on the sensor, much more than other lenses. My Canon10-22ef lens was mounted for sevral weeks and I had no dust problems.

    Does any one have the same problem?

    Strengths:    Sharp lens
    Lighweight balances great with the small XT body
    Compact design
    Lens hood is included
    Nice finish to out side of barrel

    Weaknesses:    No image stabilizer but at this price none have it so zooming in faint light makes tripods mandatory.
    Non USM AF so you can't overwrite on the fly w/o switching to MF

    Bottom Line:   
    This is a great lens for people with small SLR bodies that take thier gear into high and remote locations. I use a Hoya UV filter and the included Hood carried in a Pelican 1300 or LowePro 65 AW topload. It takes sharp pictures and 11X zoom so going from wide angle to telephone is a breeze. This is my primary lens.
