Setting F-Stop/aperture manually without sub-commnd dial?Hi All,

New here and I have a big issue - my sub-command dial at the rear of my D7100 is no longer working. It's rubbed smooth and spinning without clicking, and I am not in a location where I can get it replaced due to this pandemic. I've looked but can't find a way to manually change it? Might be missing something very simply but never had to do other than use the dial for years! I had the same issue with ISO but found that setting.

Any help would be appreciated.

F5 in your Custom shooting menu allows you to swap the function of the main and sub command dials. You could set both shutter speed and aperture by toggling this function on and off.

Page 257 in the D7100 User's Manual has the information @bugmat.

Thanks @Needa and @Marilynne - I'll try and se eif I can make a workaround.

Hi , I’m a bit confused , it’s the front , Sub command Wheel that alters aperture . Maybe this from the manual can help short term , good luck

Yes, the front dial controls the aperture. The rear dial controls the shutter speed or ISO. It you put the D7100 in Aperture Priority with Auto ISO, it should be a work-around until you get the rear dial repaired.
