The Lens at 18mm.
The 18-200mm feels very well balanced on a 40D.
The Lens at 200mm.
The zoom ring is nice and large easy to find while looking through the view finder.
A shot of the business end.
The lens seems to struggle with a little bit of lens creep (lens creep is when you point the camera down the weight of the lens causes itself to zoom) at 18mm pointed down it will stay put but twist it past the 24mm and it will slowly zoom to the 100mm area; but after that it seems to stay where you zoom it. My 72mm tiffen UV protector filter seems to need a cleaning.
The Lock button.
This "LOCK" button will lock the lens in position to keep it from lens creep I assume, please note that it will only lock while at 18mm.

When you zoom the lens it feels nice, but it doesn't glide frictionless like an L series lens.

The focus ring is nice and grippy easy to use although the 18-200mm doesn't use a USM focusing motor it is fast and fairly quiet.
A view of the AF/IS switches.
Image stablization on the 18-200 works well (this is my first lens with IS and it is a must at 200mm). Because the IS is built into the lens you actualy see the IS taking effect.
A view of the side of the lens.
Not sure what that red mark on the top of the lens is. My serial is 4501040815.
