Think about that again. If the AF works fine with f/5.6 and EV(100) of -1 (which it does as this is specification of most PD-AF systems) and if the amount of light is the limiting criterion, then AF should work fine with f/8 from EV 0 onwards. It really makes no sense to deny f/8 capability for that huge range of EV 0 to 18 (or whatever the maximum is).

Of course you're right, but I could certainly imagine a manufacturer making a ridiculous decision just to have a one-stop-improved minimum EV spec for the AF system.

Anyway, thanks for the link and for correcting my misunderstanding.
