Has anyone here used this lens? Is it a good lens overall in terms of sharpness, build quality? Happen to know at what range is this len's sweet spot?

Soft at wide open... very sharp at all range from f4...

I got the old Non DG... but with HSM... fast focus... see my gallery at www.bobtahar.com

Cos 17-70 is not f/2.8 constant - it's f/2.8-4.

So it's not that useful as the long end is f/4, that's where you need faster shutter speed to avoid handshake!

As the fonze say "exact-a-mundo"...

By the way I also have the Nikkor 18-70mm which I already sold to purchase the Sigma 18-200 OS.

Hah!!!:0...

What is your priority actually?? if you want constant F2.8...

2 best choice currently (cheaper) are Tammy 17-50 & Sig 18-50.
