pure luck.

go look at lensrental's repair statistics and their experiences getting
sigma to fix them. sigma told them 'customer damage' even when it was a
brand new lens, never rented to anyone.

I may have to put that puppy on my wish list, along with the 7D I'd use it on.
;^)

But believe me when I tell you that I'll never pay $980 for it.

Have you ever used the current version of that lens (the 18-50mm f/2.8)? It
weighs twice as much as a kit lens, and you could probably crack walnuts with
it. And unlike any kit lens I ever saw, it's a CA zoom.

Is that another one that's been replaced with Tamron's sad excuse for
in-lens focus motor?
