^ Dude just save up the money for a babydeath, that lens is a waste of money. And that camera doesn't have a filter size, so there's no threads for the fisheye to screw into anyway. I listed several excellent options so you wouldn't be wasting any money. Use them haha. The cam caddie is the only good thing there.

I feel like kids aren't even reading the thread lol.
Ben, it depends on your computer. It may not even have a firewire port. If you have a laptop, you might have to get a PCMCIA card w/ a firewire port installed on it. If you have a newer mac, you need a 4-pin to 4-pin firewire cord. Older macs, and if you have a windows, chances are it's 4-pin to 6-pin.
The camera's always 4-pin.
