The photos of my OM-D have horizontal bars appearing in jpg or raw with multiple lenses (olympus and otherwise). I'm attaching a sample at 100% (not necessarily of the region in focus). The lines are worse at higher iso but the sample is at ISO 200. I reset all settings and nothing changes. The camera is up to date (version 1.6). Has anyone else seen this? And how on earth do I get them to stop?
