Thanks Rally, and you're right! I am having fun. Lot's of it. Taking just the one lightweight camera and single high-performance lens is key. You challenge yourself to capture everything with the one focal length. I's amazing how creative you end up being - adapting to the situation rather than merely dipping into the bag for another lens or resorting to a zoom - not that there's anything wrong with that... LOL
I have a meeting in town this morning (well, a business lunch at the Malaya) so I've decided to go in a couple of hours early just to photograph the streets around Central, Haymarket and Town Hall/QVB. Can't wait to get there.
