Average good lens
I'm not a pro photographer. Before this lens, I only have the Canon 18-55mm IS kit lens with the XSi. Here is what I found.
Pros: Solid built, Made in Japan. Clear and great color dept.
Cons: Lose sharpness around the center when use in mid and long focal length.

I expected a lot more from this lens compare with a Sigma lens that I used before with my Rebel XT. I tried this lens on the new Canon XSi, tested in every mode, every setting, adjust focusing point. The result are same. IT is easy to notice that the edge and around the center of the picture is blur, regardless it was taken inside or outside and in any lighting condition. Recently, I learned from experienced photographer about the ratio between the focal length and shutter speed, it was improved a little bit.
That's the only thing I'm concerned about in this lens. I'm sure if you're an experienced person and patient enough, you can find a way to work around this problem. Otherwise, you should consider a Signma or spend more for a Canon lens.

Nice amateur lens
I had the Tamron 24-135 lens and really loved it but it accidentally was dropped and broke so I replaced it with this because it was cheaper and I wanted to try the wider 18mm. It turns out this is an okay lens for casual shooting but I've noticed many shots coming back with poor focus points. I love the 18mm and can stand in a small room and still get the whole shot in. The 200mm is decent and seems to focus fine. This is not a lens for the professional but is a nice amateur stay-on-the-camera lens.

good but not great lens
I've been using this as my primary lens with my Rebel XTi for the past 1.5 years. I tend to do outdoor photography (usually hiking with it around my neck) with a good amount of landscape and wildlife shots. This lens is great for getting the range from wide angle to telephoto without having to switch lenses (out on dirt trails) and for not breaking your neck with weight. I've gotten some great shots with this lens, but I can't blow up many of my wildlife photos because of the loss of sharpness past 100mm. I'm still undecided if the versatility of this lens on long hikes outweighs the loss of sharpness (which isn't really noticeable if you just print 4" x 6"--but who wants to do that with prized rare photos of wildlife?). I'm still a newbie to photography, but I'm already starting to get the itch to invest in some better lenses. For now, I think I'm just going to get the Canon EF 100-300mm lens to give me the sharper telephoto images that the Tamron 18-200mm leaves me wanting.

Tamron lens produces vivid colors and accurate skin tones
I am a professional portrait photographer and needed another lens for my portrait room. My two Sigma lenses gave out within a week of each other and I was told Tamron was the way to go. My images have more color punch to them. I am extremely happy with this lens.

Better lens than expected. Better than kit 18-55
I wanted a walk around lens to replace the kit 18-55 canon lens. The reviews that I read were not very good but for 0 there is not much to choose from. I was pleasantly surprised when I did some tests at home at different focal lengths and F stops and the Tamron did a lot better than the kit 18-55 lens! I then compared it to my canon 28-135 USM IS lens and they were pretty comparable in image quality!!

The only down side to this lens (the only reason it is not getting 5 stars) is the poor focusing speed in low light. Apart from that it is way better than the standard lens that comes on the canon rebels.
