Despite what a couple of dealers told me, the Inon EP01 fits on the Olympus PT-EP06 housing without any problems or housing modifications such as grinding off the light switch guard. It clears the light switch guard handily. So, I'm pretty sure it will fit on any Olympus PEN housing that has the light switch (or doesn't) so long as the thread direction is normal, i.e., turning counter-clockwise to loosen (including the Olympus PT-EP06L). I believe some of the earlier Olympus PEN housings had a reverse thread.
