Very good but the vignetting ...

I saw this on page one: "when stopped don't a bit". Smile
Re: the vignetting - after the EF III it was kinda unavoidable. Smile I see that to drive the point home, you included the uncorrected chart twice. Smile To be fair though - the same EF 16-35 III had the identical vignetting value of 4.6 EV at the wide end so I'm not sure what lenses the "That's almost 2 f-stops more than on comparable DSLR lenses" line is referring to?
Pretty odd to see an extending 16ish-35 lens, too - I thought the Sonys were the odd ones out.
