One complaint that I have about this camera is that the LCD screen cannot be moved for taking pictures at odd angles, or to protect the screen when you are done. Overall, it's a great camera. One of the lesser-known but very unique features of this camera is that it can maintain an F-stop of 2.8 throughout the entire zoom range. Most zoom lenses must reduce the aperture size, letting in less light, at full zoom. The top-notch Leica lens on this camera allows you to maintain the maximum aperture setting at full zoom, allowing you to use the zoom effectively in low light settings.
Here's my list of accessories that you may want to purchase in addition to this camera:
1. Bigger memory card (comes w/ 16MB SD card). If you want to take a series of photos in rapid succession (using the "burst" mode), a high speed (Ultra II) SD card works better. Otherwise, a regular SD card is fine. Also, several smaller memory cards may be safer, and cheaper, than one large memory card, in case a card goes bad.
2. Camera case. I just bought the Tamrac 5683. The fit inside is snug, but with a little room for a lens-extension. It's not quite the smallest bag for this camera, but it's very sturdy, waterproof and has a good deal of padding. It also has just enough room in the side pocket for extra cards and cables.
3. NC (no coating) or MC (multi-coated) clear filter. This is a filter that you can attach and leave on at all times to protect the lens. In order to use a filter, you must attach a lens hood. The camera comes with a hood that requires 72mm filters. You can also purchase a hood (e.g., made by Photosolve, Pemaraal, or Raynox) that fits 62mm filters. Why would you purchase a 62mm hood? Several reasons. First, 72mm filters are more expensive. Second, the 62mm hood is shorter and smaller than the Panasonic 72mm hood. Lastly, I don't think the Panasonic 72mm filter lets you cover it with a lens cap, though I'm not sure.
4. 62mm lens cap (for the filter in #3).
5. AC adaptor to power the camera directly. The camera does not come with this, but you might find it convenient to have.
6. Extra battery. The battery charge lasts for quite a while, but it never hurts to have a backup. CGA-S002 is the part number.
7. USB card reader for SD cards. The camera comes with a USB cable to transfer your pictures from the memory card to a computer. However, a USB card reader can be useful if you want to download pictures without turning on your camera.
8. LCD screen protectors (look for PDA screen protectors at an office supply store, and cut to size).
Finally, if you buy accessories online, just make sure you find a good price, because the online stores that sell really cheap cameras tend to overcharge for the accessories.
After owning this camera for a year and a half, I have more reservations about it. If I could, I would change the rating to three stars. I have found it difficult to get a sharp focus, and also difficult to get a clear image indoors. Granted, indoor shots have less lighting, so require a longer shutter speed with greater risk of blurring, but it is still frustrating to see only one picture in ten come out clearly, even with the motion stabilization. Turning up the ISO to 400 helps, but results in noisiness that I find unacceptable, so I rarely go beyond ISO 100. Also, this isn't the greatest camera for taking quick shots. The focusing speed, and picture-taking speed are frustratingly slow. If you want to get that perfect facial expression on your toddler at just the moment you see it, another camera will probably serve better. Granted, these are some of the prices you pay for a more complex camera with a higher-end lens (as opposed to a point-and-shoot). Also, don't mistake this for a full DSLR. My friend's Minolta DSLR focuses in a split second with a satisfying click of the lens body. The Lumix sometimes focuses over more than a second, going in and out of focus until it tries, and sometimes fails, to find the focus (again, in lower light conditions).
My wife now wants me to buy a Canon powershot. She gets frustrated with the Lumix because she can't figure out how to adjust all the right settings, and it looks like I'll have to give in on this one.
