*ist-DS ISO warning function

[David Oswald]

The *ist-DS has a menu setting by which the user can request that an ISO 
 warning light up if a predetermined ISO sensitivity is exceeded.  To 
me this feature makes a lot of sense if one is shooting in auto-ISO 
mode, where the camera moves up to a higher sensitivity if not enough 
light is available to take the shot at handheld speeds given the 
currently set ISO.  In auto-ISO mode, it is very useful to have the 
little ISO light turn on in the viewfinder if the camera has chosen to 
set its ISO above, say, 800.

But that's not quite how it works, at least for firmware version 1.01. 
The ISO sensitivity warning does light up if the user manually selects 
an ISO that is at or above the warning level.  But the warning doesn't 
seem to trigger if the camera's auto-ISO selects such an ISO automatically.

This seems like a nearly useless function, as it currently works.  Why 
would I need an ISO warning to trigger when *I* set my ISO above a level 
that *I* predetermined to be the warning level?  In my mind the only 
real need is to be warned when/if the camera automatically selects a 
high ISO.  ...but as I just mentioned, that doesn't happen.

Can anyone else confirm/deny, or otherwise shed light on this quirky 
feature?
