Using my D850, 500 PF lens, I was shooting in full manual mode (aperture, shutter, ISO). I increased exposure compensation and the shutter speed dropped. I expected (preferred) the ISO to change instead. Is there some camera setting that specifies which variable changes with exposure compensation. I do use auto ISO often, but sometimes it isn't what I want. Thanks.
Camera setting changes with exposure compensation.

If you would like to post, you'll need to register. Note that if you have a BCG store account, you'll need a new, separate account here (we keep the two sites separate for security purposes).
Something's not right there. In full manual mode including manual ISO the only thing that should change as you dial in exposure compensation is the way the meter reads in the viewfinder. No settings should change at all.
If you do want the ISO to vary with exposure comp then shoot in full manual with Auto ISO but if you're actually in full manual with manual ISO setting then nothing should change other than the meter reading as you dial in exposure compensation.
I'm not aware of any camera setting that would cause shutter speed to vary with exposure comp while in full manual mode. I'd double check all settings to make sure you didn't accidentally switch to aperture priority mode and if not then maybe try a full camera reset as something isn't right there.
FWIW, I just picked up my D850 and tried to recreate what you describe and I can't find any settings that would shift shutter speed with exposure comp while in full manual mode including manual ISO.
Thanks for your response. Now that I think about it, you are correct. I'm not sure what happened or what I did incorrectly. Perhaps it had to do with my excitement of being only about 30 feet from an immature bald eagle in big dead cottonwood and my 1st outing with my new 500 PF lens.
If you hit the ISO button, hold it and turn the front dial it changes the camera from manual ISO to Auto ISO and vice versa. My Z6ii is set to just tap the ISO button without holding it down. After tapping it once I can make all the changes I want before tapping it again, or hitting the shutter button to turn the ISO adjustment mode off again. And yes, I've inadvertently changed my camera from manual to auto ISO this way by not paying attention. 
LOL, that could be me.
Pretty sure it's been most all of us at one point or another...LOL, that could be me.

On my D 850, I use Auto ISO, but in Aperture Priority mode. In setting Auto ISO I set my desired shutter speed. When I dial in Ex comp , Plus or minus, my ISO changes. This is what I want to happen.
I've just put my D850 in full manual mode and set 1/50 at f4. I then moved the exposure compensation up and down fully and on the display the shutter speed and aperture did not change. I then took 2 pictures pne at zero EC the next with +5 stops EC and looked on the LVD and again the shutter speed and aperture were still 1/50 at f 5.
The behavior you describe is perfectly normal in aperture priority mode, so the first question has to be are you sure you were in manual mode?
Second question is if you were in full manual mode why use exposure compensation?

I have not said this on this forum before but with 40 years experience I always tape up the front and rear dials before a shoot. The only thing I change on a 1500 shot shoot is to turn the flash on and off . I also pull the electronics out of the Grip and just use it for battery storage or for a GPS tracker

Interesting..
Raises the questions (hope you don’t mind me asking.)
What subject(s) do you shoot? And what are your settings?

Interested in this too, assume it must be subject dependent? Couldn't use that technique myself, quite often I'm shooting at 1/80th then the next shot has to be 1/2000th.
I assume this is for studio work where lighting remains constant? This would not work if I’m chasing wildlife or birds that move around outside because the light is constantly changing.
Very kind, Sir.Pretty sure it's been most all of us at one point or another...

Aperture mode ,F8,auto iso 200 -6400 ( so it goes to 800 with the flash on) 1/60 min FP 1/350 ,2 FPS then tape up your dials and go shoot your wedding. Change to P mode for the dancing (no flash) Tape up the lens switches too and the manual focus ring.
I keep spare AA in the grip on one camera and spare ENEL 15 in the other.
Different sort of bird ..often with no knickers to avoid knicker line....oh what fun.

Okay a wedding means a once in a lifetime occasion and you’ve got to deliver.
Clear, thanks for the headsup.
(Expected somehow your answer LOL)
