E-M1X won’t update a lens with two batteries loaded. I needed to take out one battery for the E-M1X to be able to update lens firmware. I did not try to update to 1.1 because I have major shoots coming up that I don’t want to bother with firmware until after.
E-M1 mkII updated to version 3 with no problem. Some notes…
- Custom Menu A1, AF+MF is OFF by default. Turn this back on if you use S-AF+MF or C-AF+MF.
- Custom Menu E1. Low ISO processing… change this to Detail priority for best image quality, or Drive priority if you need the fastest FPS you can get.
