As it turned out, my camera is not threaded for a filter. :cry:
The only option was a filter holder called shoe digi-holder which screws to the bottom of the camera and extends to the front of the lens. It's kinda funny looking but it works. It came with 2 filters, (a filter sunset 2 ref A198, and a filter star 4 Ref A057); and 4 adaptor rings. I can't use these rings for now but I'll keep them for when I upgrade. I also picked up a circular polarizer A164 which looks too dark but when I used it, the pictures were ok.
