On the M9, I concluded that setting aperture AND shutter speed manually and letting Auto ISO take care of the ISO was extremely useful. What I did not like was using Auto ISO in conduction with aperture preferred (on the M9). Herbert Kanner kanner at acm.org 650-326-8204 Question authority and the authorities will question you.
