I can't believe you would test a brand new lens that has not even hit store shelves yet on old discontinued cameras! I've owned many of those camera models on my way up to my current A77 and there is no comparison in image quality. I can't imagine many people in the market for this lens would still be using it on any of these old cameras. The test results would not only be more accurate but I am sure the lens would have better results on the new cameras. I am going to check your Nikon 80-400mm lens tests and see if you tested it on old discontinued cameras too. In the interest of fair comparisons I hope you did.
