Olympus quietly released another firmware update for the E-M1 mkII. This seems like another small bug correction. It improves operation of the EVF. Not sure exactly what is being corrected as their description is vague. However, I have communicated with people that have had odd behavior in the evf when switching between manual focus and autofocus using the clutch. Maybe the bug was related to this? Anyone know anything more? Regardless, it is probably a good idea to update.
