Afternoon all,

I've been reading a lot about lenses recently and I was wondering if someone could tell me what the mm figures relating to any lense refers too. I can understand that any lense with a large range of numbers (Eg 70-200) is going to be a fairly strong lens, but how can I tell whether I'm looking at a wide angle lens for example, or a macro lens?

Thanks very much,
