Quote:That's correct, it wasn't f/4, but who shoots landscape wide open? So, the vignetting might be technically there, but in practice it is no problem.PZ only mentioned it vignettes a lot when used relatively wide open. So, not sure why you seem to disagree? Canon thought it was a good idea to offer f4 on that lens. Maybe they don't think it is that irrelevant (they even offer f2.8 on FF UWA zoom).
