Nikon 8518 vs Canon 8512 - What's the Difference?

I think Sony's lenses are always kind of the best when it comes to lenses in general. You get 15 frames a second max when you... I mean, do you really need more than that? Unless you're a sports shooter, for the most part, 15 is plenty. But the focusing speed, if I, you know, comparing it to, let's say, a 51.2, may be able to get more data through it and might give you better autofocus just from my using it. And speaking of Sony lenses, I do think they are the quietest lenses. I think they're the fastest autofocus lenses. They somehow make them the smallest lenses too.
