So a battery charger with its versatility, the loading possibilities - even in the car - one of each camera. It is incomprehensible to me that this Olympus not standard mitliefert at the relatively expensive camera as in my previous Olympus cameras. To load only the battery in the camera is impossible, if you want to take pictures for longer. Loading and shooting must be able to run in parallel. The addition of 2 spare batteries is optimal. So one of the power goes out determined not so fast. I can only recommend this product.
