The sensor itself is also quite reflective, think some of the reflected light bounces back on the sensor again?

The flange distance being a lot shorter in m4/3 cameras (compared to reflex cameras) that phenomenon has to be taken into account. That's why Olympus, who has a huge experience in electronic microscopes (there lenses nearly touch the subject), has allowed its camera division to access its technology in order to apply these sophisticated coatings at the back of their lenses in order to minimize that.

This is one of the secrets that explain the amazing sharpness of most of the recent primes made by Olympus.
