Who is shooting in -3EV anyway?

I, and others, gave you examples were it is useful. If you brush them aside as not valid because it is not your shooting style then why start a post at all.

My opinion is that a camera that is capable of shooting up to 102,400 ISO but won't focus in low light is out of balance and not very useful. This is enough argument to make -3 eV focus sensitivity very useful. Personally the 5DMKIII should have had this too.
