Any vignetting in the 15-35?

AFAIK, vignetting is inevitable, even in super teles, which have very little of it (a fraction of a stop), but do have it.

Question is how much vignetting would the RF 15-35mm have. Under two stops @15mm f/2.8 would make me very happy.

[For reference, @16mm f/2.8, the EF 16-35mm f/2.8 mk II has 2.8 stops, and the mk III has 4.6. The difference was discussed on this forums in the past, IIRC it was claimed Canon preferred sharpness over vignetting, and apparently a bit of barrel distortion.]

The firmware updates are very welcome, and long anticipated. I'll look forward to more details about them.
Exactly what I was waiting for the Eye detection so I can stay in this mode if it performed well! Since I don't do to much action it should be fine!!! I can't wait! I spoke with the canon Rep yesterday I should be on the list in Canada to get my hands on the first batch of the 24-70 I hope I can get it before a big calendar I will do in the south with 12 gorgeous models! I will be able to test everything over there!!!

Not that I've found. I'd love a simple 'in/out' option like I can set with One Shot - Servo mode.
you can costomize pretty much everything, I have set mine with a button so it switch only to 3 different focus mode. so I don't have to cycle trough all of them. The eye detect, the small single box, and the larger one after that.
