I have a Panasonic Lumix FZ7 and I'm looking at the accessory page and it has a couple of lens protectors. The problem is there isn't a description for any o this stuff. I was wondering if its something I should think about.

Also, what does the adaptor do?

The Telephoto lens, worth the money? I'd like to be able to get a bit closer to my Wildlife subjects, the 12x is good, but I usually can't get up close and personal.
