>>203657 It's useful, though not as much as on a long lenses. You'll gain exposure speed alright, but the additional effects dont come into play as importantly as in longer/standard lenses. You can't easily generate bokeh with that focal length, even at 2.8, or it wont be anything to write home about.
Because depth of field is so large by being a wide lens, focusing will do a minor job. Additionally, the stop difference between a 2.8 and an F4 of any other wide lens will not likely be enough to ruin your shots.
Wider lenses are easier to use for handheld shooting. A 1 stop difference like that one helps a 50mm waaaaay more than it helps a 14mm lens.
Additionally, if you're doing landscape shots or urban landscape pictures, you ought to close down the aperture anyways, so again, 2.8 vs 4 is hardly worth it.
Opinions, though.
