5D and WFT-E4A question

[A-Teague]

Sorry guy/ladies if I'm in the wrong room.

I'm thinking of converting over to Canon and have been looking at the new 5D Mark II with the battery grip. But before I do, I'd like to know if the Canon WFT-E4A FILE TRANSMITTER f/5D-MARK II could be used in place of the battery grip or do I need both?

Thanks in advance!

You can't use both at the same time. If you want wireless file transfer or the other benefits of the WFT-E4, that's all you need to get.
