Mark, Georg - the 24/2 master - have already posted good advice to you.
My relatively short experience with the 24/2 ais revealed that for landscapes I need at least f/8 for border to border good sharpness.

HDR sunset with the Nikkor 24mm f/2 AI-S
D3 + 24mm f/2 Ai-S supported over the windowsill, remote cable, ISO 200 at f/8, base exposure 1/2s, plus -1EV and +1EV; slight 5% crop.
The reddish cast was what my eyes saw at the moment, no overdone HDR.
I have no 24/2.8 yet, though I am at a bidding race for an old non ai 24/2.8 N.C (Curtis guilt!!!) at the moment , but I suppose this and the ai/ais versions are better lenses for landscapes, as Curtis and now Tony have showed previously.
On the other hand, if you are planning a lot of bokeh playing and some artistic shots the 24/2 lens supposedly is better than the 24/2.8.
