Thanks for the kind words Archiver & Mike! I think that this kind of casual documentary usage is where the Fuji system really shines. There are better tools out there for studio portraits, billboard advertisements, etc., but I'm less interested in those kinds of photography.
RE: lenses, the original 35mm f1.4 has a nice look, but I imagine the newer f2 version (which I don't have) might have been more reliable in AF performance, especially in low light with fast-moving subjects. But use what you have, right?
