18-200mm Canon lens, it's what you expect from the biggest company. I was very surprised when I got it out of the box, it is a lot heavier than expected, which brings along the problem when you have the lens about halfway and look down or up than it opens or closes under it's own weight which is a...

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

Brilliant lens to whoever wants a lens that can perform at wide range of lengths, I would strongly recommend.

Build quality; Image Stabilization; good range of length so know need to change lenses

Weight; movement in the lens because of weight; price

I use this lens in every day in church with excellent results.

Durable; Easily Interchangeable; Fast / accurate auto-focus; Lightweight; Strong Construction

Fantastic Purchase. Great value for money. Always have on the body, no need to constantly change lenses. Would highly recommend, as an all round lense.

I owned this lense before. Unfortunately, the barrel should be locked while in carrying mode. Otherwise can be fragile fully extended.

Easily Interchangeable; Fast / accurate auto-focus; Ideal all around lense

Lens Creep

It is great not having to switch between lenses for everyday shots, both close-up and at a distance. I highly recommend this lens.

"Covering 18mm to 200mm provides a huge amount of versatility with this lens. If you need to travel light and can only bring one lens, this might be perfect for you because it was for me.

Pros: Great overall lens, allows me to take only one lens. Pictures look great. Cons: Only annoyance is that the lens 'trails out' when hanging by the neck strap. Seems like that could have been engineered out.

I've had this lens for about a month. I've used it for some landscape, some street pictures around town and some shots of flower gardens and macro photos of flowers. I've used it on a 50D body and a T3i body about equally.

Lightweight; Wide Focal Length Range

Lens Creep; Poor image quality; Poor in Low Light
