**********************************
K' `( h8 `# u9 H: ]+ k: c7 @* |Anyhow, you pose a good question - f/4 IS or f/2.8 non IS. Here are the main points:
) V+ w' U( {5 t, j
: l3 X; t. A/ N1) 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/4.0 k4 H1 C8 L: J6 c
2 i, {8 t& S4 L3 K7 }
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.

3) The f/4 is lighter and smaller. Winner f/4.

' d5 J+ U% I% P4) The wider aperture of the f/2.8 can offer more creative possibilities, especially when taking portraits. Winner: f/2.8.4 a$ a( N& ?/ y. Z

5) The f/2.8 has better bokeh (creaminess of the blurred areas). Winner: f/2.8. |
