You also need to find the aperture where the lens is sharpest. The 100-300 at 300mm is sharpest at f/7.1 for instance. Quite a lot better than f/6.3 and a lot better than f/5.6. I have no idea where the Oly is best.

I never shoot my 100-300 wide open for this reason.

Excellent point, Tony. One of my frustrations is that every lens has a different sweet spot. Some lens are okay at wide open. I may have to write a cheat sheet and paste it on the camera or lens.

I will try to test multiple apertures.
