I finally bit the bullet tonight and paid for the digital camera I've been saving up for/lusting after for about two months. Panasonic Lumix DMC-FZ20k Anyone else have any experience with this camera, or anything similar? 10x or 12x zoom, 5+ megapixel, digital SLR types of digital cam? Any one here a professional (or experienced amature) photographer? Any tips or must-have filters, travel case, etc?
