>>4106900>it's fine across the frame even wide open at 17mmI owned one. I know how it performs. I couldn't give two shits about your autistic sperging so you can "be right" in an Internet debate, or your whatever-website test numbers. The 17-40L was better overall on crop. And when I went FF, it was replaced.
>Oh, and show me a 11-26mm f2.8 crop lens that outperforms it, lol.A Tokina 11-16 f/2.8 @ f/4 produces better corners on crop than the 17-40 f/4L on FF.
