Field test: Shooting Roller Derby with the Olympus OM-D E-M5 II

James McDaniel is a self-taught photographer with a special interest in roller derby. He's also a Micro Four Thirds shooter, so when we were looking for someone to test out the E-M5 II in the real world with us, we immediately thought of James. Watch our latest video field test to see how how the camera performed on game day, and don't miss an opportunity to see Barney on roller skates. See video
