What's the best way to fit filters to P&S digital cameras?

Hi all, I have many 58mm filters that I use with my film SLRs. I was

wondering if there is a contraption out there that would allow me to

fit my big filters to my small Minolta G600 digital P&S. If so what

is it called and where can I find it?

There is no filter threads of any type on the G600's lens or barrel.

So I would assume that something would have to hold the filter out in

front of the lens.

Anything would work as I would probably be taking the shots on a

tripod as I usually do, so portability is not an issue. I have tried

to make my own adapters but the results aren't perfect because I am

not a skilled craftsman. Plus these home made attempts have often

turned out inconvenient making it difficult for me to switch filters

with reasonalbe speed. Thanks for any help.
