Sigma 18-200 OS

I've been using the Sigma AF 18-200mm f/3.5-6.3 DC OS since June now here are some of my thoughts.

Pros:
Optic Stabilization
Lowish Cost
Comes with Lens Hood
Great Zoom range
Compact size.

Cons:
A bit heavy
Slow Auto Focus
Can't nudge the Auto Focus

Nutshell:
With an 18-200mm zoom range this works well as a lens that can stay on the camera most of the time. This is a good thing with the "dust on sensor" problems inherent in a DSLR. The lens ends up being a number of compromises. The price on Amazon is great, the Optical Stabilization works well and is a real plus in shooting. The Autofocus is sort of slow and hunts a lot in low light. The lens could be a bit faster but all and all for the Amazon price of around $462 it is a good buy, and has become my primary lens. Oh yeah, and the pictures turn out pretty good too.
