I love my M-D and the ISO control on the back. There are the usual numbers - 200, 400, 800, 1600, etc., and there are two stop points between each one so, in theory, one can graduate between the known values. I like this control.
I see the M10-D uses the ‘rewind’ ISO control. Does that too have 2 stops between each labelled value? Or is there a lower level of control on the M10-D?
