Yesterday I stumbled over an MTF test of the Sigma 24-105. A new one, although the lens is available since 2013. But it's from Roger at Lensrentals, so could be of interest: https://www.lensrentals.com/blog/2018/02...ries-lens/
Although vignetting is not part of his tests. It's just a comparison to the Canon 24-105 and Nikon 24-120 (which was better than I thought). And one paragraph in his report says, the numbers stopped down to f/5.6 were amazing, too amazing to be true and he is retesting it. And I'm loooking at it like "maybe it is a bit more than just another 24-105..."
