I've had my E-M1 since it first came out. It's been a total joy and the best camera I have ever used. But now it seems to have died. Just now it powered on fine and when I zoomed in with my 40-150 PRO everything went black. Tried cycling the power switch. Nothing. Changed the battery. Nothing. Changed the lens. Nothing. The power meter had read full last night when I checked. Tried battery #3. Still nothing. So I am guessing this is a catastrophic failure. Could it be the power switch? I am charging the first battery at the moment to see if maybe it was just a matter of the batteries all being dead, but that seems highly unlikely. Anyone else experience anything like this?
