Wondered if there's an easy reference to show the barrel distortion of several known Canon lenses. Maybe a PTLens file report would be useful.I wanted to compare my cheap lenses today to a possible L upgrade soon.For example, is the 24-105 L IS significantly "flatter" than the 28-135 IS, at both ends of the zoom.
