Several year s back I injured my lower disk making carrying a huge gear bag to shoots / events, tough before the action started. As this was slowly getting better the micro 4/3rds world was developing some great cameras. I found the OMD-E-M5 MkII a super multi camera in one, its controls are configurable and its a great video camera. With 5 way image stabilization and essentially water tight it get the job done under most conditions. Built in Wi-fi for easy xfer to ipad.
