If you are intending to photograph scenes, then I woouldn't suggest a walkabout. Park yourself on a spot you are happy with, set up and wait for the light. If its for architectural stuff, its the usual stuff you see from my photos I would recommend, The Esplanade, Gateway(look out for the guards), Pinnacle at Duxton and in general buildings within the CBD which are tall enough to catch strong sublight.
There are a few tilt/shift and shift-only lenses from Nikon. I'm using the PC-E 24mm. I used to have the TS-E 24mm MKI from Canon and got rid of it soon after I got the PC-E 24mm. Also using the TS-E 17mm as well. Ocassionally, I borrow a PC-E 45mm for assignments. These are the 4 I've used.
