When I used EV adjustment function, on that function screen, there is a green colour square (or rectangle as you can say) box on the centre of the screen and the box is movable.Do you know what is the function of that box? Thanks! (I've read the manual, but it doesn't mention that box)

雖然好仔細、準確，但真係要想想有咩用？^_^
