This was actually an interesting exercise.. I ran some resolution tests on my 80-200 earlier this week, and the results were disappointing enough that I sent the lens off to the Nikon repair facility to have them check it out. Significant chromatic aberration effects were clearly visible, and this is after the D700 is supposed to be correcting for lateral CA. The corners were very soft too. It was bad. The center of each image was ok, probably why I've been happy with the lens on my D100 and D2X all these years. I figured I should test the remainder of my lenses, just to see if there were any surprises there. Thankfully, there were not. Surprisingly, the one lens that was as sharp wide open as it was stopped down some was the 14-24. That thing is some kind of crazy sharp lens. My ancient 50 f1.8 AI wasn't bad either from about f2.8 on. I bought the 80-200 used and I've had it a while, so it wasn't entirely surprising to find problems there. I bought a 300 f4 AF-S and a TC14E used as well, but those both seem to be fine. My homemade resolution target won't be running rigorous lens benchmarks anytime soon, but it's good enough for a rough equipment check. FWIW, you can get the ISO charts here.
