This is f3.5, all auto lens corrections set to OFF, levels/white point adjusted to 255. Should have been at f2. But what's the verdict? I see a little more cyan vignetting/cast in lower left, this is consistent with a few other shots today. Not sure I care.
When I white balanced using the center of the photo, and brought exposure down a little bit with this shot, it does seem like the bottom left corner has some cyan shift, and the other three have a bit of magenta shift, but it's tough to tell whether it is a big deal or not. Like Carsten mentioned, we need some infinity shots at f2 with a tissue over the lens, pointing at the sky.
