Focal blur, a how-to, please, if possible?

I would love to know how to do focal blur in Blender if it’s possible, thanks!

Do you mean a depth of field blur effect? It is limited at the moment but search DOF or try this link:
It is only a post effect achieved through Composite nodes and has the disadvantage of bluring edges adjacent to the background (blurred bit), oh and it’s difficult to adjust the focus over time (pull focus).
Hope this helps

Whoa, I’m sure that would help, but I basically don’t understand ANY of that, lol. If I had time to read the whole thing, I’m sure it would be useful, but I’m busy alot :-/
