I was cleaning my Canon 60D camera house and everything, and I took off the battery grip to make sure there wasn't any dust or whatnot inside.
Then I noticed something, there seems to be set aside space on the arm that sticks into the camera house for ... something.
Does anyone know if that is correct, and then what that "something" is?
Here's pictures of the space:
There's even some small "arm" that I would gather something would fit behind, perhaps to hold it in place. It doesn't fit anything inside the camera house so it doesn't appear to have any purpose at all. You see that "arm" best on the second photo.
The small light gray square block extruding in the lower right corner of the area (best visible on the first photo, to the left of the arrow pointing left around the center of the photo) is a rubberlike block of foam, again supporting my theory that something is meant to be fastened in here.
There doesn't seem to be any way to connect anything to power or the camera itself though, so I don't understand what it could be.
