I think I discovered something odd with the User Presets.
I just noticed that when I go to U1, U2 or U3 I can’t set my i menu the same as I have it in M, A, S or P modes. I never really thought about it, but if you go to a user preset you might want to go into the i menu and it would be nice if it was set up identically to that in your M.A.S.P modes. You can’t for instance set up the Release Mode.
Incidentally I am using the latest firmware 3.1
