Yeah. I would like to go to a big city and take pictures.
I do not know what I should buy next. I like night and I like macro.

But is the USM slow+ I thin ki heard something about it.
uh USM is short for Ultra Sonic Motor and it makes the lens focus fast and makes almost no noise
I've heard those lenses
without USM, like the kit lens you've got with your XSI/450D, are slow and noisy

hmm if you are into night photography you probably should get a lens with wide aperture. the ef 50mm f/1.8 II is a cheap lens and good one even though the build quality is poor but I am sure if you dont plan on to drop it or anything it should be satisfy your need for a night photo lens unless you want to zoom too. then you may want to look at ef-s 17-55 f/2.8 IS USM which cost like 1200 dollars or the much cheaper Sigma or Tamron 17-50 something f/2.8 lenses
