Sigma 18-50mm f2.8 lens

[ameerat42]

Folks,
I am wondering about how good this APS type lens is:

Sigma 18-50mm f2.8

on cameras of about 18MPx, like the Canon 7D and similar Nikon (and any others).

Does anybody have it? Any 1st hand experience? Any pictorial examples?

Ta, Am.

There's a test of it here for you.

Ta Benny. That was a good read. I will not now break my neck to get it, but spend some money elsewhere.
