This is a very nice lens at a price that is very reasonable. It is sharp and clear, focuses quickly, and is a real pleasure to use. Because of the extreme range of this telephoto lens, it is not necessary to be changing lenses as often. The macro factor is a plus! I own several other Sigma lenses and I like them all.

I bought this for trekking with my camera because of its wide range. The hope was to reduce lens changes which introduce dust into the camera sensor. I like the high quality feel (not "plasticy"), and the fact that the lens achieves the wide range without being large and heavy. It doesn't quite have zoom power for birds and wildlife that my 500 zoom has, but it comes close enough, and has enough "wide" angle for some scenery shots.

A real bonus is the macro capability of this lens!

I wish it a were higher speed, but then it would be larger and much more expensive, reducing it's utility in backpacking situations, and breaking my budget.

Great lens for the money.
