It's often surprising to buy an expensive camera if you then only buy accessories with which one sets the performance down. The best example is a fast camera and a slow memory card. But even with the right battery you can save yourself a lot of annoyance. Who characterize the non - holidays and suddenly the battery is low or after a few shots empty. In my view the replicas come to a maximum of 60 to 75 percent of the original battery.
I have chosen for this very reason for the original. However, I have acquired it at your local dealer, because there was a price advantage there.
