On the manual focus, one direction focuses closer (macro) and the other direction focuses further, I think at the furthest end of focusing, it's infinty...usually the symbol is the sideways "8"
Still a little lost, how can it be infinity? The focus ring (or whatever it is) has a size.
And when your focusing, it still goes in and out of blurriness and stuff like focusing using MF on an AF lens, right?
