Hello there friends! I am trying to become familiar with the things people talk about on the forums, and I am also confused about certain things. First question: What does it mean when people talk about a 'Fast Lens'. For instance, people will say, "I know, I need a faster lens". What is this referring to exactly? Is it the speed at which it can auto-focus? Second question: Since I have the D60, I know that I need to get a lens that is a AF-S in order to have auto-focus enabled. So the question is, if you don't have auto-focus, how do you focus? I know this may sound stupid, but to manual focus do you just twist the zoom lens until you have the picture in focus through the view finder?
