I've used Canon lenses for eighteen years, and they're just as sharp over the entire f-stop range now, then when I first bought them. You can probably get by with an inexpensive body; afterall it's just a "box" that holds the film. I've always held the belief, that if I'm going to invest top money it's going to be good lenses. To caveat I'm not an employee of Canon, just a satisfied customer.
