I need a bit of advice regarding possible upgrade. I currently run with the Canon 7D and have done so for seven years. I am looking at what would be a logical upgrade. Obviously the 6D Mk II and 5D Mk IV are in my mind as the best possible candidates but I would also like to hear your experiences with the 6D Mk II in particular as well as any other recommendations; esp as I know next to nothing about the mirrorless department.
