@ briveira
you are right
the menu code does not notice the change to ISO 100 because it shows it as the default selected option whenever you have a non-standard ISO selected
, this is not a problem.
I will change some code to force it set iso to 100 when press SET right after show ISO diaglog.
I shoot a hundred pic today and it turn off my 400d's display one, and i face another problem that when in play mode delete button not work.
Thanks!
