    I understand that a lens with a large zoom ratio is considered to be of lower quality than a prime or lower zoom ratio. I've been considering a sigma 18-200mm OS lens which I've seen decent reviews for, but I'm wondering just how much of a difference it would make in terms of quality. I generally like landscape and wildlife, which requires both extremes and would rather not change lenses for every shot. I currently have the nikon 18-70mm which I'm quite happy with, but was wondering if anyone had pictures taken with a 18-200mm lens which would show a noticible difference in image quality.

    Thanks.

    I'm pretty sure my photography teacher has one... He was the spokesperson for Black's photography and is now a manager for Henry's...he shoots weddings and travel photography...teaches courses...

    Now I'm not sure if it's the Nikon or the Sigma one...but I know it has VR...so...

    It can sometimes be worth the tradeoff in sharpness to get a huge range if it'll let you get that shot you would have missed otherwise. Think of how useful it would be to YOUR photography.

    I don't know about the Sigma one. I own a 18-200 VR Nikon one.

    If I get a chance in the next day or so I will post some pictures and you can see for yourself...

    If you are going to be taking pictures of test charts, this is not the lens for you. If you are going to be taking pictures of non-moving subjects in low light handheld, and need a large range, it may be.

    I have generally found that people who hate this lens (the 18-200 VR) have never actually shot with it, other than perhaps the odd occasional snap in a camera store.

    I am one of those people never used it and have no interest in using it. I have waay better uses for $700+ than blowing it on a marginally sharp slow lens. I understand the size issue but personally I think image quality is way more important than convenience.

    I own one, I use it and I like it.
    I have the Nikon 18-200 VR and when I go travelling I love it, it is light, compact and fast enough for most situations. Go to the store and test one out, Rent one if you can and try it out. I do not know anyone who owns one who does not like it.

    I had one, used it for a couple of weeks and brought it back. As a convenient point and shoot apparatus it works very well. The lens is nice and sharp in mid apertures and the VR really does work. I did not like the lens creep and I found it very slow in the long focal lenghts. I got an 18-70 for a general purpose light zoom that my wife likes on a d70. It's a little sharper in wider apertures, does not creep and distortions are a little less noticeable.

    all my pictures are taken with my Sigma 18-200mm DC 3.5-5.6

    and i'm very new to photography and i think the lens is great

    big distortions at 18-35 mm ish though, can't even think about taking portraits with that

    Hmm..

    16 elements in 12 groups.

    ...that's a recipe for sharpness.

    It's okay, though, because three of them are aspherical, which you'll need to stem the distortion from the other 13.
