And I am speaking from use....the Q and 85 are right here beside me...I can handhold it for most of the trime at 1/60....any 400mm, and I would need faster.

What 400mm f/5.6 have you used  on FF?  But if you want to show us a q+85 @f/1.4 and 1/100 at ISO 1600 handheld shot, please do.  I'll then attempt to recreate it with 5DII+100-400L@f/5.6 1/100 @ ISO 25600.  I have enough pixels to crop a little to get the same FOV so the 400 vs. 480 difference can be handled.

Any longer focal length but especially with a physically longer lens, I will not get as slow a shutter speed as a physically shorter lens.

If that were true than 500mm mirror lenses would be much easier to handhold. They aren't.

Actually, i thought it would be too far away and impersonal though i like a 300 2.8 for portraits...in practice, for smaller adults and children it will be a useable combination with a little room to move.

It's kinda creepy and stalkerish....

Not seeing it.....again varies camera to camera.

Doesn't vary that much for contemporary cameras.  Exactly what two cameras (one FF, one 1/2.3") are you looking at where you can't see the difference?

Forget to answer this one?  What camera pair do you think you don't see it?  The DPR tool can be found in every review....
