A few days ago I updated my Sony 100-400 GM lens from version 1 to 6. I can't tell if it performs any different, and it's certainly not worse, but the programable buttons don't function and are no longer shown in the menu.
I don't normally use them so they won't be missed, but I am curious, has anyone else experienced this bug.
Sounds like there is a problem somewhere that you have not discovered yet. You may want to see a Sony rep somewhere to get the update fixed.
