No lens in this catagory is perfect, you have to accept each lens shortcomings...this lens works best with the canon auto focus system hands down, tamron and others take forever to focus and often frustrate. While not perfect...clearly works better than others.

Consistent Output; Fast / accurate auto-focus

Heavy; Lens Creep

This is a great do-it-all lens covering probably the most frequently used focal lengths that the majority of people will use. Its not a substitute for a good prime lens as the compromises of a superzoom mean a trade off in overall sharpness, however this can only be seen in extreme enlagements and...

Easily Interchangeable; Quick Focus; Rugged; Strong Construction

I bought this as a replacement for one of the same model. It is a very versatile lens and I use it frequently, I have used it for over three hundred photographs in the last month. My original one is probably repairable but I needed a replacement urgently.

The focal range of this lenses is perfect for the types of photos that I take from sports to wild life. It is very fast to focus and easy to adjust the zoom on the lense.I feel for the money it is one of my better lense purchases.

This is a handy general usage lens. I basically use it for my kid's sports events where i am sitting far away but I don't want to bring 2 lenses. So I bring this one. I'm no pro, but i do notice a slight image quality difference between this and my f2.8 17-55mm lens, but it's still pretty good.

I bought my 550D with the twin lense kit which included a 18-55 and a 55-200. I only ever used the 18-55 but then 12 months ago I bought the 18-200 lense! It is much more versatile and the 18-200 lense travelled with me all through the US and UK on a two month journey and performed wonderfully.

Superior build quality; Super-sharp images

I bought one of these EF-S 18-200 with a 500D as a kit 2 years ago and carted it all round Southern, Central and Northern Australia, China and it has served me well as an all rounder.

Great lens, awesome Wide Angle & Zoom! Perfect all round lens. Smifu is definitely the cheapest place by far as I did tons of research before I brought it. It also got delivered in 48hours!

Meets my expectations with ease. Loving it.

Solid; it has a stabilization feature; allows a degree of freedom; quick response time and the focus is quick too

No issues
