Quote: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).I don't see your point and I don't disagree. I just wanted to pint out that technically vignetting is visible, but that in practice it is no real problem as hardly anybody shoots landscape wide-open.
@Klaus: Yeah, I guess you make it right for everybody. What ailed me was that in your summary of the test results you weighed too heavy on the vignetting, which - again! - won't be much of a problem in the real life.
