close up filter is a filter for attaching to lens.  Then you can take at a closer subject distance.  There will be different magnification close up lens marked as either +1, +2, +3 etc to denote diff magnification.

A close up lens is a specially designed lens ( marco lens) use to take close up photography.

Welcome to ask any question!  Everyone begins from asking and acquire his knowledge. No need to shy!

Of cource there are limitations.
eg the range of subject distance is limited.

s602 has macro itself. It's macro is quite great but has its limitations.

close-up filtering is to extends 'another' macro ability on its normal lens. so you can use its normal 6x zoom lens to do macro shot.
However, it also suffer from some limitations.

So... are they useful? depends on your situation.
From my experience,

built-in macro/superMacro:
pros
-easy to use (click 'flower' and use)
-can shot in close/very close distance
cons
-3x zoom only
-magnification is limited
-image is relatively dark (b'coz your lens too close to the subject)

close-up filter:
pros
-6x zoom possible
-magnification is higher (depends filter type, +1, +2, +4, the bigger the higher)
-can retain longer distance between the lens and the subject
-so, the image does not suffer from 'lens shadow'.
cons
-DOF(Depth of Field) is very short
-Focusing Distance is very short
-therefore, need some time to practice how to use it properly
