Panasonic Lumix FZ20 adapter...help!

[Lanimilbus]

I've been searching for months for an adapter for my Panasonic Lumix FZ20 and have had rather horrible luck. What I'm trying to find is an adapter that will attach to my FZ20 and allow a 52mm threaded telephoto and/or a 52mm threaded wide-angle lens converter to be attached to it. Basically any adapter that will step down and allow a 52mm threaded lens converter be attached. So far I've found this: https://secure.soligor.com/index.php?id=5&backPID=415&L=1&tt_products=6568&L=1

and this: http://www.bugeyedigital.com/product_main/ray-rt5264p.html


...but both have such little details and look so sketchy (one spelled "adapter" wrong on the thing itself) that I'm not sure that they'd work. So, could anyone here tell me if either of those really would do what I'd want them to, and if not, if any other adapter exists that would work with the Panasonic Lumix FZ20 and allow 52mm threaded lenses to be attached?

Thanks a lot in advance,
