Ok the sample is good and hard to explain CA and vignetting by sample variation, quite a disappointing review, however would it be possible to test another sample ? the results seem too bad to be true.
OK this is a thanks for the warning style review........
......surprisingly uninspired sharpness from 50mm up at the borders, poor vignetting and CAs... and all this from a top of the range expensive OEM lens...huge heavy and expensive!
I suppose the question is: Is the Tamron better? at the longer end it looks to be, has better CAs and can be bought for a lot less money!
The Tamron had its share of gotchas as well methinks - like vignetting and distortion - but the resolution seemed better in both Canon- and Nikon-based tests. And then, the G2 version is looming...

The Sony 24-70mm f/2.8 is probably the only fast std zoom lens that is good. I don't expect anything from the new Sigma and Tamron.
But then this is a useless lens category - not really fast, excessively heavy and big, very expensive relative to what they offer. PERSONALLY I couldn't care less.
Something like the Canon 24-70mm f/4 makes more sense.
But we are all different.
