These few drawbacks are true but eventually arrange me to delivery, I received this case with two foam inside to protect it from being overwritten (indeed, should further packaging because the case was very slightly crushed but without the leather is thereby damaged, that is to say without bending). A first placed at the bottom and a second placed inside. I got the first foam I realized a notch to place my second memory card, which solves my second point. I placed all in the background. Thus placed, my camera is now very well positioned in its case, which solves my 1st point.
Regarding the battery, I'm not sure that, for reasons of electrical interference, to have it near the camera is a good idea.
