The Vignetting Comparison Tool
has been updated. The biggest change is that the test results have been regenerated and output at a larger contour results image size. All images are larger, but APS-C images are now shown full-size as well. Full frame lens results will delineate the APS-C field of view via a superimposed frame.
The ISO 12233 Chart Resolution Comparison Tool
has also been tweaked - primarily to move the sample images higher on the page (for less scrolling).
