The EM-5 sensor, as exceptional as it may be, has a coating on its attached hot mirror that reflects purple light off axis:

many digital cameras of this type have such a hot mirror; often there is a combination of absorption filter (cyan color) and reflection (interference) filter that will produce the magenta/purple off axis glow. So the question would then be why the EM-5 has this problem and not those many other cameras with similar hot mirror. IMHO the hot mirror is an unlikely cause.
