Had to get a new cable as I got a new MacBook Pro laptop recently and the firewire connection is upgraded from the old iMac G5 (2005) I was using previously (from firewire 400 to 800 I think), so I needed a new cable to connect my new MacBook Pro to my Canon XL1 video camera. This is the cable that does the job very well.
I choose this cable over the others on Amazon as it was listed as a 'Pro' cable and looked quality and I wasn't disappointed (especially with the good price). I am very pleased as this is a really good quality cable (always a worry when ordering cables online). It has a good quality build and nice professional design and silver/steel metallic finish with plastic coating and the connection was really fast with no problems. Similar cables in PC world were £17-£24 so this is a great deal.
Just to confirm, as it took me a while searching for the right cable - this cable fits the firewire for the latest MacBook Pro released in 2010, which is Firewire 800 I believe. So if you've just upgraded your mac and wondered why your cable no longer fits from your firewire connected device, this is the one. :)
I ordered this cable from Neet Cables and it arrived very fast - within days of ordering.
