9 k0 S9 |. M8 @ m8 R$ j& m, T7 @4 p1) The f/2.8 gives you one extra stop of hand-holding possibility, but at the cost of depth of field, whereas the 4.0 gives you 3 stops of hand-holding possibility at any aperture. Winner: f/4.

2) The f/2.8 gives you one extra stop of light in darkened conditions when photographing moving subjects. The f/4 doesn't. Winner: f/2.8.
