Didier, I think they are discussing an error that occurs with that camera's
metering, or perhaps an issue with the actual value of the marked stops on
the lens. Never happen with an M Leica ;-)

IMHO opening one aperture stop means getting the double light?
So from 1.4 to 2 you should get half of the light?

>from 1.4 to 2 you do get "about 1/3 more light"  (well a little over, but
not much more) or am I mistaken?
