Back button focus

[Raymo]

I have 'lost' my BBAF ability and haven't found out why. I used the settings recommended in Steve's Nikon autofocus system book as follows: Focus Mode set to AF-C; Under Custom Menu: AF-C Priority selection "Release"; AF Activation is "AF-ON only". The AF-ON button doesn't work. If I switch back to "Shutter/AF-ON, AF does work. Does anyone have any suggestions for what might be going on? Thanks

What camera are you using?

Sorry about not including it. It's a Z6II

For BBAF "AF activation" under the custom settings A menu setting (it is a6 on my Z8, a Z6II may be a different item number) should say "OFF". Is it set to off?

If not in the AF activation menu go to the sub menu AF-ON only then next sub menu and ensure "Out-of-focus release" is set to "Enable"

@Raymo

My Z6ii BBF works OK. In the list of things that you posted I don't see custom settings>controls>custom controls>3 right hand clicks n the multi-selector to get to the AF-ON button where you can assign the function you want.

I suspect the same thing as Graham -check and see what the AF-On button is programmed for under F2 in the Custom Settings Menu. If it's not AF-On, it won't work as expected.

Got it! Thanks to all.
