It's clear in the pictures by Martin, but not dramatic.

I wear glasses with varifocal lenses. A common problem with such glasses is that you have to find a spot on the glasses to look through to get sharp vision, depending on the distance to the subject. With the first 12-40 image I can find a spot where the image is crisp but with the first 12-50 image it is as if there is something wrong with my glasses as I cannot find any spot to look through so that the image becomes crisp.

It isn't dramatic as you can clear up such "fog" by means of added contrast and sharpening. I think that if these images were shot in RAW, the CA corrected and a bit more contrast and sharpening applied to the 12-50 image the pair would become much harder to distinguish. So the 12-50 is by no means bad but the 12-40 is clearly better. Images that require less processing end up looking better upon close inspection. But if CA were corrected and contrast for the 12-50 increased a bit then the images would look the same when viewed on a large computer monitor. Such monitor has a resolution of 2MP (soon going up to 4MP) and that is enough of a downscaling to make the differences disappear.
