New Full-Frame Vignetting Test Database
http://www.the-digital-picture.com has recently added full-frame vignetting test results for a large number of lenses. The results show f-stop contour lines as well as a rectangle indicating the x1.6 APS-C frame coverage.
Results are available up to f/8 both bare lens (pure optical vignetting / light falloff) as well as with a standard-thickness UV filter attached to the lens so you can see the additional effect of physical vignetting. You can even compare two different lenses on the screen together.
It seems like the results were mostly obtained using an EOS-1Ds Mark II body. Measurements were conducted with Imatest.
It didn’t take me long looking at the tests reults to see that the Canon 24-105 f/4 IS USM exhibits a lot more vignetting than the Canon 24-70 f/2.8 USM lens on the EOS-1Ds Mark II body.
