For Oly users

There is a lot of information stored on the E, OMD and pen cameras. Things like shutter activations and such. To get to it:

Begin by inserting your camera’s battery and holding down the ‘menu’ button while you turn the camera on.

As soon as you see the LCD illuminate, release the menu button and immediately press it again.
You will now be presented with a menu; select the ‘SPANNER’ option and click to the right using the direction pad.

Scroll down to the brightness screen and click to the right once again.
Select the INFO option and then select OK.

You will be presented with a screen that says ‘OLYMPUS’.

Enter the following code sequence: UP, DOWN, LEFT, RIGHT, SHUTTER, UP.

The hidden information should show up!
