I bought this camera a few days ago to upgrade from my Mju 300. It is a lot sleeker looking with more added functions, including a whole range of shooting modes. The ones I have tried so far, such as sunset mode and nightime with portrait mode have worked really well. Another big advantage is the 5x optical zoom as most other basic digital cameras only have 3x zoom or less.
The camera is easy to use and looks really stylish, I would advise buying a 1GB memory card to ensure you can store a few hundred pictures on it. The battery life is also not great so get a spare one - it takes a Li-42B rechargeable, do not be misled on the Amazon site with the Li-12 or 10 batteries which state they are suitable for the Mju series. Also, a case is an essential as not included with the camera.
Overall, a great little camera, just needs a few accessories purchasing and unfortunately on Amazon they are all from different sellers which means paying over the odds in postage!
