Hi, I'm looking around for a good quality digital camera, but I don't know which ones to choose. I narrowed my choices down to three brands; Canon,Olympus, and Nikon. If you guys have any other brand that i didn't mention please inform me. The requirements are: 4x optical zoom and up, 5.0 megapixel. The price range up to $300 US. It will also help if you guys give me the model type for example, Olympus C-5500. I hope you guys and girls can help me out again. Thank You!
