Well, it seems I am one of the lucky few who have actually received a copy of this brilliant lens.
Previously I had a Canon 17-55 IS, Sigma 50-150mm f/2.8 OS, Sigma 30mm f/1.4, Canon 50mm f/1.4 and Tokina 11-16mm f/2.8.
I have long felt a slight disappointment with the Sigma 30mm and the Canon 50mm. Both offer great center sharpness but not so much in the border areas. So for me the 18-35mm was a great upgrade from the Sigma 30mm f/1.4. I've always felt I wanted a wider prime, and now I have just that.
I'm selling both the Sigma 30mm and the Canon 50mm since I know I will never use them now I've got the 18-35 which destroys them both in the IQ department.
Before getting the 18-35mm I thought that my 17-55mm f/2.8 IS would still be my walkaround zoom, but now I'm not so sure ... So the 18-35mm may end up replacing as many as three lenses. The jury is still out on that one.
