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 field test video to see how the camera performed on game day, and don't miss an opportunity to see our very own Allison Johnson in action, and editor Barney Britton trying out roller skates for the first time in his life - all for the sake of camera testing.
