No I am not saying that, You do use an adapter but the adapter that came with the FZ5, while it is a little too long it is nowhere near as long as the one that came with the FZ20.
Everyone is using the one that came from panasonic with good results.
Most need to at least do the sanding, I mentioned and some are doing Fmoores modification but for just Filters and teleconverters the little sanding trick is all thats necessary.
There is a chance depending on the thickness of the filter she gets that there will be enough threads to work with no sanding but, I would imagine she will need to sand.
You can then use the hood that Pansonic provided either in the stored position or the in use position.
And while it seems there is one aftermarket adapter available no one seems to be able to get it.
Pay close attention to what Fred Moore says in this thread.

And then this is how he made a really good FZ5 adapter but this is not necessary except for heavy lenses or a wide angle lens.
