Earlier this week, Fujifilm released updated firmware for the X-Pro1 and X-E1, bringing focus peaking and improved autofocus performance. Unfortunately, something seems to have gone wrong with the version for the X-Pro1, and the firmware has now been pulled by Fujifilm.
In a statement on its website, Fujifilm said:
According to some reports, the problems with the firmware are more widespread than just with video. Have you tried the new firmware? Had any issues?
