Some point and shoot cameras will have the ability to select some settings. What I use is a DSLR which use interchangeable lenses. A Canon Digital Rebel would be the least expensive DSLR and the camera body with a kit lens (non-macro but may still work to get started) and will cost @ $750 for the latest model. The previous model with the same kit lens would be $500. Check out B&H Photo on the web. They are very reputable.
