Hello, ran into some issues with my E-M10, have several lenses, batteries. love the camera. had seveal problems after an encouter with "water" hiking. do not often need water proof, though. Only issue lately is No Flash. Should I up upgrade to E-M10 Mark II ( this week sale with Olympus ) $ US 549 and a Pro lens 14-40mm ( $699 ) curious on your thoughts, or advise.
