i have a d7100 and i use easy iso , i assignt it to the back scroll wheel , i use aperture priority and use the front dial to change aperture , rear dial for iso and keep and eye on shutter speed to focal distance , if you need fast or slow shutters you can manipulate iso and aperture to get what you need
i was the same , very frustrated having to look for the iso button and change it ,using the rear dial you can use it while looking through the viewfinder easily , you wont regret trying it
You beat me to it.
to set it up. go into custom settings
then D shooting/display,
D3 iso display,
show iso/easy iso,
press ok.
to operate, press and hold the iso button on the back of the camera (4th one down on the lefthand side)
and use the thumb wheel to adjust.
