Recently watched a three hour webcast on using the EM-5. Got lots of tips on setting up the camera but the best one was how to fix that aggravating long cord on the Olympus battery charger. The Mac Book Pro comes with a power cord and adapter. If you want to use the long cord instead of plugging the power unit direct to an outlet, then you must remove a little plug which happily can be plugged into the Olympus charger which can be pugged directly into the wall. Goodbye long Olympus cord!
