You don't need a DSLR to use filters with your camera. Cokin sells a magnetic filter system that's compatible with most compact cameras. A small or medium metallic ring fits around your camera lens and keeps the filter holder in place. If your camera has a tripod socket, you can use the Digi Shoe Holder instead, which screws into the bottom of your camera. Both holders work with Cokin A-Series filters, which can be purchased in kits with the holders or separately. Stock up on color, infrared, diffraction, graduated, center-spot, and star filters.
