hi, everyone
i got my brand new Z8. there is no PSMAC123 dial. how could i save my setting? i had set shoot 2 mode to 15/1 iso 2000 F5.6 for flash. but sometime i would adjust some setting based on that moment, for example: F3.5 and 20/1 shutter speed. and then, sometime, i will change to shoot 3 to do continuous shooting without a flash. then, i will switch back to shoot 2 , but its still F3.5 20/1 . i want it back to 15/1 F5.6. i need the old one C1, C2, C3 seting, please help
The professional Nikon bodies (eg D850, D5, and now the Z9 and Z8) have never had the custom settings options, but uses two Menu memory banks. A "shooting menu bank" and "Custom settings bank". And as an aside if you want the Shooting menu memory banks to save exposure mode, shutter speed and aperture you need to switch on the "extended photo menu bank" option.
The philosophy of using menu bank memory is rather different to the one of using custom memory options C1,C2 etc as they only remember a limited number of controls and are "dynamic" in that they always remember your most recent changes and don't take you back to the original settings you saved in memory.
They don't really work, if you want to save static changes ie one set of settings for landscape and another for action, but work well if you want subtle changes though a days shooting.
I have the shooting menu set up for three different bird photography settings, one for fast flying birds (menu bank b) , one for slow flying birds (menu bank c) and a third for static birds (menu bank d).
Menu bank B has a starting setting of 1/2500s (set up at home), but if its bright day and it's very fast flying birds I might change this with the control wheel to 1/5000. If I switch subjects to static birds I change to Menu bank D, which among other things has a saved shutter speed of 1/800s.
Now, and this is where the menu banks are different to the custom menus, if I now switch back to fast flying birds (menu bank b) it doesn't change back to 1/2500, but has remembered that when I was using this menu bank earlier in the day I had set it to 1/5000, and that is what it changes back to. It will also remember if I also switched from aperture to manual mode etc. At the end of the days shooting I set the menu banks back to my defaults.
So, as I said the menu bank approach is more dynamic than the custom menu option and adapts to the shooting conditions as you work. I'm fairly confident this is why this approach has persisted on the Nikon pro bodies.
They are much more difficult to get your head around, and not great, for the "save and forget" approach that the custom settings allow for. However from what you describe, they might actually work fine for what you want.
If you google Nikon z8 (or z9) and shooting menu banks, there are lots of videos going through how you can set them up and use them. There have been subtle changes between camera models (I use a D500, and I only do wildlife with it), but the basics has been the same for close on a couple of decades so older info is still going to be useful.
