I really do not see why. Sure, the sensor should not reflect much light,
but how hard can it be to compute the amount of light that has fallen
onto the sensor when you know how reflective it is? Even if reflection
is only .1% this seems verye feasable to me. For me It is still a big
miss in all DSLR's, especially coming from Olympus.

Someone care to elaborate?
