">this page on the website</a></div>I shot a LOT of photos with the 70-200 2.8 mk1 and I've shot the mk2 for almost a year. Both are good copies.
The mk2 blows away the mk1 in every respect. The mk1 was a good lens for its time, but the mk2 is a good lens - PERIOD. Primes? Why bother?
Something has gone horribly awry in your testing process for this not to be reflected in your measurements.
