450D grip contacts information.
5 months ago
Let me start by saying that my good friend Google didn't come trough this time.
I'm trying to find information about the contacts used by the battery grip, the ones inside the battery housing. Is there any info on how they are used, what does each pin do? I'm trying to build an intervalometer that will be housed in an battery grip and using those contacts seems the most elegant solution. Also, does any one have an old, no longer working, grip that they might sell a bit (a lot) cheaper? I really don't wanna buy a new one just to take it apart...
