Can anyone help me understand the meaning of focal lenght in a camera? This is the definition that I have but it's a vague definition.

1. The distance from a lens to it's focus.

What and where is the focus?

2. The distance from the lens to the point at which a colimated beam of light entering the lens is brought to a point.

Uh?

you're welcome - it looked like pretty solid info and pretty down-to-earth, too (not like some photography sites where they try to impress you with their technical knowledge without actually telling you much)...

Very Happy I know. That is the impression I have of the website also and why I've bookmarked it.
