Here's one of my tests shots for purple fringing, loCA,and other high contrast nasties. Taken from my truck at a stop light, a large commercial vehicle was next to me. 300mm wide open (high ISO):
Not much there to discuss, is it? The VS is my second best lens, beaten only by the superachromat. E.g. the Canon 300f/4LIS show comparably severe fringing and loCA. Just for the sake of comparison (so nothing quantitative here), if the LIS suffers "ten times" stronger CA, it is just "twise as" sharp as the VS. And the minute advantage in sharpness is immediatly lost if the focus or exposure is not spot on. If this is the weak end of the zoom range, I have to say that I find it pretty sufficient for what ever challenges there is. We are discussing the final few percents of physically attainable performance. Yes, I´m still as amazed by this lens as when I posted the OP. Images from skilled photogs do support it nicely, I think.
Yes, we are splitting hairs. This lens is a super performer - regardless. Thanks for posting. It got me looking - and I found one
