a7II customize rear dial for ISO

[oneeye]

When I have to shoot fast in photo journalism, I don't have the time to bother with A or S, so I use the P setting and adjust using the front dial for a compromise.  But sometimes there is not enough light so I have to lower the camera, redial the ISO, set it and then, again, find my subject focus and shoot  -  and the picture is usually gone by then.  It seems to me that the two - front & rear dials work the same, a waste of a useful feature.  So, I would like to know if it is possible to customize the rear (only) dial to change the ISO.  That way I can keep the subject in sight while only turning one of two dials to set everything needed for a fast shoot.  This would work well, but I don't know if it is possible with the current software.

Any suggestions?

Not sure if that is possible; If you use ISO Auto, you could use M option which allows shutter/aperture to be changed with front and rear dials, the camera will set the correct ISO for those values.

I agree with LiveShots, try ISO Auto. Adapting Jim Kasson's manual exposure strategy

1. Decide on the f-stop you need based on DOF, not the light.
2. Decide on the shutter speed you need based on motion blur, not the light.
3. Then [let the camera] set the ISO...

Thanks.  I know I can set the ISO to auto but the separate use of both front and rear dials - rear for ISO - would be a great feature,  just like customizing the buttons.  Too bad Sony doesn't have this customization feature available for these dials.

I can only echo others sentiments. Let the camera choose the iso values, s/speed and aperture are your main concern operations wise.

Probably just me and my big clumsy thumb, but I really dislike the rear dial.  I find it very difficult to rotate it without pressing one of its button functions.

@tinplater Do you mean the control wheel (13)? ISO can be assigned to that but, iiuc, not to the rear dial (9).

I would also love this customisation, to have the rear dial control the ISO. The lens I'm shooting with has an aperture ring, so I don't need that feature on dial.

I don't know about your camera, but on mine, if I press the ISO button with my index finger, I can immediately and easily change the ISO with the rotating rear dial using my thumb.  Perhaps yours operates this way as well.  Perhaps not.

The Rear wheel on the A7II is recessed further away than the optimum position because the slope of the body below the dial is too shallow.  If you look at A7III, you can see the slope is much more steeper bring the real dial closer to the thumb.  And then having the C3 button so close to the dial doesn't help the situation either.  I end up accidentally pressing the C3 button if I am slightly more aggressive in turning the dial.

The only thing you can do is to train your thumb to become familiar with the rear dial's position and remember where the C3 button is located.  Turn the dial lots of times so it becomes more responsive.  For the first while the dial was hard to turn but it gets easier when you work the dial back and forth.
