Acessort lenses for digicams

[Mogodore]

[font color=\'#000000\']Does anyone have any experience with using accesory lenses on their digicam? What sort of results did you get?

I'm particularly interested in Raynox or Century Optics if anyone has used them. Based on what I've been able to find the seem to be the best available - short of the camera maker brands - and they cover a wider range of magnifications.

Second thought - are the camera maker brands camera specific or will they work on other brands of cameras?[/font]
