When we look at how panasonic and panaleica lenses score and when we look at similar lenses from other brands, there seems to be little reason to think the 100-400 mm leica will need to be stopped down seriously to obtain excellent results. Of course we can not be sure at all, but I have good hopes it will do well at 400 mm and think even @ f6.3.

Exactly!

If the lens was branded Panasonic Lumix, it would have been most likely an f4.0 - 5.6 lens. It was probably Leica's stringent image quality requirements that forced Panasonic to stop it down to f6.3.

I expect sharp images with this lens wide open with no need to stop it down for better sharpness.
