Sorry my English is bad.
I'm having a different issues with the new 1.50 firmware. I have the r6 and r5. After updating both to the new firmware, I notice on the r5 that the M-fn button doesn't work like it use to.
Before, when the M-fn button is pushed the the "DIAL FUNC" menu will appear. Now when the M-fn is pushed it doesn't nothing. The "Customize button" mapping is still at default at "DIAL FUNC"
Because I had a wedding on Saturday, I had to find a work around by mapping the AE* Lock button to "DIAL FUNC" and it works normal.
On the r6 with the new firmware (1.50) everything works normal.
Also, I was not able to downgrade the r5 to 1.40 in EOS Utility. It won't let me. Is anyone else having this issue? I will be calling Canon tomorrow and see what they say.
