Hi Duncan,
Just to make sure we are talking about the same things, the D500 offers three different "banks":
1. Photo Shooting Menu bank
This one includes all the settings that are adjusted by the Photo Shooting Menu (the one with the small camera symbol). Examples here are quality settings (RAW or JPEG), storage folder, file naming or ISO settings (AutoISO etc).
2. Custom Settings bank
This one includes all the settings that are changed in the Custom Settings Menu (the one with the small pencil symbol). This one includes a lot of settings like AF customization, metering settings, bracketing and self-timer settings as well as button customization, to name a few.
3. Extended Photo Menu banks
This last option is actually more of a special case of 1 (Photo Shooting Menu bank) and you can turn it on or off in the Photo Shooting Menu. When turned on, basic exposure settings are saved as part of the Photo Shooting Menu banks. Example: Photo Shooting Menu bank A can be set to Manual exposure while B can be set to Aperture Priority. If the setting is turned off, changing from Manual to Aperture Priority in one bank will also change the exposure mode in the other.
Personally, I don't understand why you want this to be turned off. Without this settings, the Photo Shooting Banks seem quite meaningless to me!
I hope this makes things a little clearer.
I too found this system in the beginning really confusing as I came from a camera that had different User modes on the mode dial (which I still think is the better solution).
I can offer you a quick overview over my use of these banks:
Photo Shooting Menu banks
(with Extended Photo Menu banks setting turned ON)
A: Standard wildlife mode
- Manual with Auto ISO
- Modest shutter speed (around 1/800s)
B: Action wildlife mode
- Manual with Auto ISO
- Fast shutter speed (around 1/3200s)
C: Standard/landscape mode
- Aperture priority
- ISO 100
- Different storage folder to differentiate wildlife and landscape photos
I have set the movie record button to allow switching between the Photo Shooting Menu banks, so pressing the button and turning one of the dials cycles between these modes. This way, I can quickly switch for example from a quite slow shutter speed to a fast shutter speed when there suddenly is some action.
Custom Settings bank
A: Wildlife
- Restricted AF to AF-C (meaning when I go to this setting, I always will have AF-C, so I don't need to check the setting)
- Pressing the joystick will activate Group AF
B: Standard
- No AF restrictions
- Pressing the joystick will activate Auto Area AF (which I like to use in some cases but never when doing wildlife)
(These are just two quick examples but maybe the most important ones to me)
Switching Custom Setting Banks is unfortunately not as quick as cycling through the Photo Shooting Menu banks. I have set up the Fn2 button to go to the first entry of My Menu which I have set to Custom Settings bank. So one click on Fn2 opens the list of the saved Custom Settings bank and I can quite quickly switch.
This got quite long and specific and your needs may be completely different but I hope you got some pointers on what is possible.
As I said in the beginning, I am not a huge fan of the banks but they can be quite useful when you configure them to fit your needs. This initial configuration can be a bit tedious but may be worth it in the end.
Cheers,
Lukas
