May I quote another Roger Cigala post?
"Recently, the good people at Imatest have developed an ultra-high resolution, backlit chart printed on photographic film that is perfect for testing long telephoto lenses in the lab. The combination of a new, cool Imatest setup and a new, cool lens proved irresistible, so we decided to compare the new Tamron with the olderTamron 200-500mm, Sigma 50-500mm OS, and Canon 100-400mm IS lenses."

Please note: I don't see lensrentals and PZ competing for the "best results". Each of you guys does a great (and free of charge for us users) job and together the results are stronger.
