Well it's like the title says; mounting my Canon BG-E7 grip to the body leaves a large gap. I've tried it without the battery compartment door in it's storage place, thinking that might be the problem. However it changed nothing.
The thumb wheel seems to be turning freely, so there is no binding on the threads. I can't see anything that should be causing this to not seat flush...
I'm going to try and get a picture showing the fit...
Anyone have any ideas?
EDIT: Okay here is the picture.
