The 16mm fisheye will do it (I recommend the Nikkor f3.5 version over the f2.8, if you can find one). The 16mm is compact and light, very sharp, and an excellent landscape lens if used with understanding.
The fisheye perspective does have the advantage of keeping foreground
and background size relationships much more equal than even a much
narrower angle of view standard lens like the 15mm would do. The
fisheye perspective does impose one awkward requirement: that the
horizon be near the center of the photo to avoid objectionable
curvature (the swing-lens panorama camera alternative [like the
Widelux] imposes the same requirement). A little ingenuity using interesting sky, an overhanging tree or rock outcroping, or a bit of judicious tilting if the horizon line is interrupted and not clearly visible over much of its (photographed) length can do wonders to
solve fisheye perspective "problems", giving you nice images of the sweep of a landscape (or an entire canyon, etc.) in a single 35mm
slide. BTW, I like using 16mm's with the TC14A for a nice alternative superwide angle of view (performance with the Nikkor 16's is excellent
on the TC14A converter by f5.6).
Hope This Helps
