Yes. I recently discovered how auto ISO works (use it with manual mode). I never used auto ISO on my DSLR (D850 and D500), but recently moved to Z8 and started using it. It works great most of the time for wildlife, but I found out over the last month that trying to use exposure compensation does not work (since I am in manual mode). On my DSLR's I used aperture priority with exposure compensation when needed.
The problem with the Z8 is that you have to go into the menu to turn auto ISO on or off (which is annoying - why can't they just put it in the ISO dial: spin down to the lowest ISO and then spin again and the next setting is auto). If someone knows of a custom function that will activate exposure compensation with manual and auto ISO, then please tell us. If not, I may go back to using aperture priority because I like having quick access to exposure compensation.
