There's also an alternate accessories catalog available here. However, if your looking to buy anything, you'll be hard pushed to buy them from any official Panasonic shop (well, that has been my experience).

I've recently managed to find seller(s) on eBay that can supply Panasonic accessories quickly & cheaply, in particular the UV & ND filters for the 46mm lense. If you need any details about the eBay shops I used, send me a PM, or reply to this thread, and I'll supply the details.
