Ah the only problem I have with this logic is "stopped down to F 2.8".
I have a roomful of lenses only a quarter of which can be "stopped down
to F 2.8" as the ARE 2.8. Or they are slower. You must be mainly into
the much faster glass and forget than most mere mortals OPEN UP to 2.8;
not stop down to it. I suspect or remember you have the 85 1.4.
My first lens on my first camera was a 2.8 so for some reason anything
faster than that I think of as "fast." On a normal or very short tele.

I do have a Noctilux though and stopping down to 2.8 is stopping way way
6 clicks. 
3 stops. 
The "middle" of the lens f stops as they are engraved on the lens is
f4!! Kind of where you'd expect f8 to be there. (really)
