I've used the Fuji S5100 (very similar to the S5000) with the Olympus TCON 17, which gives 1.7x magnification to your camera. You have to fit the plastic lens adapter ring (a tube shape) onto the front of your camera - this should have come with the camera but you may not normally use it. Then you screw the TCON onto that.

It works well and you can get decent images. The more zoom you have, the more camera shake becomes an issue, so you will need to get a tripod, or rest it on a fencepost or whatever. Not sure how much these lenses now cost (eBay?) but you might instead want to save up a bit extra to get a more modern camera, e.g. one with some sort of image stabilisation which will allow you to shoot in lower light. I still use my Fuji sometimes, even though I now have a better camera, so it is worth hanging onto.

With any of these lenses (Raynox, Opteka etc.), you just need to check that the filter thread of your camera is the same as that of the lens, and if not you can buy a step-down or step-up ring, which will allow the extra lens to fit on.
