Personal insults are not allowed on this forum.

but you don't seem to refrain yourself from doing it, hypocrite!!!!

or you are just intentionally miss understanding. A f/4 lens will most definitely still be able to achieve focus in lower lighting conditions than a f/5.6 lens and that is what we are talking about.

We are talking about why they will perform the same, all other things being equal.

You can work it out by solving the f/5.6 + ND filter vs f/8 conundrum.
