Olympus has issued updated firmware for its latest PEN models to better cope with the recently launched Micro Four Thirds power zoom lenses. Firmware v1.2 is supposed to result in a more accurate display of focal length on the camera display, in EXIF data and in playback. Firmware can be downloaded either via the Olympus camera software or by using the 'Digital Camera Updater' utility downloaded from the company's website.

Olympus statement:

Today Olympus announces the release of new firmware for the E-P3, E-PL3 and E-PM1 that more accurately displays the focal length data for electric zoom lenses shown in playback, EXIF data, and in the monitor while shooting.
