Olympus E-PM2 Super Control Panel (SCP)
The Olympus Super Control Panel is a special hidden control system. As you can see above, it makes viewing and changing settings on your camera really easy. It's not turned on by default. Here are simple instructions on how to enable it.
I own 3 Olympus Pens, the E-PL1, the E-P3 and E-PM2. I can confirm that all Olympus Pen cameras, since the old E-PL1, as well as the new OM-D have the Super Control Panel (SCP) option -- they are all turned on in the same way.
