Hi all, I was wondering if anyone knew about a battery-grip-styled grip for the EPM1. I don't need to actually supply power to the camera, but want the additional bulk. The EPM1 is a fantastically compact camera, but I would really like some additional bulk to balance out the weight/mass when I mount legacy glass like Canon FDs. It would also help with using telephoto zooms. I believe the other term for it is a vertical grip?
