I have come across Dzone2 on eBay which than become a fans of them as I do not need to pay GST when I got my little camera. Big saver for me :)
Anyway, they are holding a competition on facebook which ends in March about "filters". You will only need to upload a photo to show what other purposes filters are for apart from mounting on lens and you will get B&W, hoya filters and cleaning sets. They are top quality brands which worth more than 80USD each.
link? And its already march.
