General

The downloadable OLYMPUS EP50 firmware archive contains the necessary file to update the OLYMPUS EP50 camera firmware to version V4.0_20230523 as well as instructions on how to perform the update (PDF file). Please read the instructions carefully before performing the update.

Changes / Corrections

Firmware “V4.0_20230523” corrects the following issues:

• Movies acquired with the camera’s embedded OSD software exhibit a periodic brief pause when played back
• After formatting the SD card with the OSD software, saved files were only shown when the camera was restarted although they were correctly saved to the SD card

The current firmware version of the camera can be verified inside the camera’s embedded OSD software (click on the “i” button in the bottom tool bar) or inside the EPview (Windows) application software.

To do so please start EPview (Windows) and check the information given under “Device settings” > “Camera” section > “Information”. To access the “Device settings”, please open the “Acquire” menu > “Devices” > “Device Settings…”.

Cameras with a firmware version lower than “V4.0_20230523” should be updated.

4. Insert the SD card into the OLYMPUS EP50’s SD card slot (camera must be switched off first)
5. Switch on the camera by pressing the power button. The blue status LED will start blinking quickly, which indicates that the firmware update is in process.
6. After around 6 minutes, the status LED indicator will blink slowly before staying lit permanently. This indicates the firmware update has been completed and the camera has successfully rebooted.
