Very good macro shots can be done by the FZ10 without any accessories (for example, see the Hover-fly on pear tree blooms (alternate link) by MSgt Jimmie Burton (USAF Retired) -- and Jimmie seems to be an accessory freak! Jan in CA also has a very nice FZ10 `macro' gallery.
Information about the FZ1 macro (apparantly similar information applies to the FZ10 macro)

Comparison between Olympus B-Macro and Raynox Macro-Explorer set (f8, hand-held, external bounce-flash) -- by Clint751 (dpreview, Panasonic forum, 16 March 2004). Clint (and others) report that the B-Macro has less vignetting than the Raynox Macro-Explorer at lower zooms (especially less than 10x). Clint also says camera-subject distance can stay the same while zooming with the B-Macro. Clint also has further comparisons between the B-Macro, Macro-Explorer and a Hoya +4, using just a piece of rope to compare focus (depth of field) and curvature.
I have had the Olympus B-Macro lens {+2.5, two-element lens, 55mm thread, almost certainly the same as the Olympus MCON-40} since a I got my FZ10 a couple of months ago and love it. I just got the Raynox MacroExplorer Set today from B&H. I think they have different strengths {some people say the 1.5x is a +4.5 and the 2.5x is a +8.5. both are two-element lenses}...the B-Macro can be used throughout the zoom range but I can get greater magnification with the Raynox...
...I don't think the Raynox is quite as sharp to the edge as the Olympus, which is specifically designed for a flat field; but, the Raynoxes are pretty close to flat field, especially at smaller apertures...{look at this dpreview discussion for more technical information about how to attach the Raynox Macro-explorer to the FZ10, or see Section}.
A distinct advantage of the B-macro lens is the increased distance between subject and camera. You get maximum macro at 12x zoom at about 11 to 12 inches (the Raynox lenses are probably more like 5 or 6 inches).
