I currently have a Canon Powershot S1 IS digital camera, and I'm looking to get a few different kind of filters for it, but I'm a bit new to professional-ish photography and I was curious if anyone could help me clear up something I'm a little confused about.

I was looking through the instruction book and it says that to be able to attach any lenses or anything on, I need to buy their special Conversion Lens Adapter LA-DC52E (link ), and then I can attach either a tele- or wide converter, however I can't attach any filters or lens hoods to the converters.

My first question (if anyone knows) is whether or not I should be able to attach a lens or filter to the Conversion Lens Adapter, or should I expect it to only attach the tele- and wide converters?

My second question is do you think any third party photo company might make any converters or adapters that would be compatible with my camera? I figure Madcatz makes video game controllers for X-Box, Playstation and Nintendo, so maybe somebody out there makes equipment that's compatible with cameras they don't make. If anyone has any knowledge of this kind of stuff I'd love to hear anything you might have to offer.

As always, thanks to all you guys for all that you do.
