I wondered about this also, so experimented this morning.  Like the others
responding, I set the shutter speed and aperture manually and let the camera
(Fuji X-E1) pick the ISO (range from 200-6400 for raw files).   It appears
that the camera is using the exposure mode selected to determine AE (i.e.,
spot, average or multi), and you can change it even though not in AE mode.
Also I notice that AE/AF lock works for recomposing (although the ISO
changes it you move it way off the mark).  Very neat.  I think this is a
good solution for the Fuji at least, since it has little noise at higher
ISO's.  Thx for posting the question - always something new to learn.

In a recent thread,  Mark Rabiner cleverly argued for a new approach to vary
exposure, that raised eyebrows, but has received support and accolades. 

Rather than varying  f stop or time of exposure Mark pushed the idea of
varying ISO settings using  AUTO ISO. Ideal for many conditions this is
being widely used. Fast digital cameras NOW have various AUTO ISO systems
built into the program options.

I generally shoot fast glass at full aperture, in aperture priority mode.

I would like to learn more about Auto ISO mode, its use, strengths and
weaknesses, impact on the results...from Mark and other 

friends here, so please don't hesitate,


thanks, Steve
