Interesting problem with Olympus EP-1 and 14-42mm
I found on 43rumors.com interesting link to an article on Imaging Resource - here. It's worth a read because it shows that mirrorless cameras can also be affected by "mirror blur". Of course the cause of the problem is not mirror, but the shutter itself. Imaging Resource tested EP-1 with 14-42mm lens and found that at 1/100 and 1/200 shutter speeds you cas see blur in the pictures . The cause is probably movement of lens elements caused by the shutter.

The blur is always vertical and only few pixels high so there is no reason to panic.
They made great comparisons and even a graph which shows why the problem is visible on shorter shutter speeds and not on longer ones.
