In any event, I strongly recommend that the OP does not take photos during the landing. IME, photos of the view of Sydney city centre almost never come out nearly as well as it looks to the naked eye. There is, in general, much to be said for not spending one's entire life missing the great views to be had in this world simply because one is always staring through a viewfinder or at a tiny display screen on the back of a camera. It is much better in this case to actually look at the view. Much better pictures can be bought.
