We'll have to wait another year to find out:https://www.facebook.com/photo.php?fbid=456583604400854&set=a.108293225896562.11313.102447209814497&type=1
Optimal Prime: Given that the X10's auto ISO always seems to choose a higher ISO than necessary, I have a nagging suspicion Fuji knew of the problem even prior to release.
For instance, when the Auto ISO is set to 800, despite being outdoors on a sunny day, the lowest ISO setting the camera seem settles on is still ISO 400...
This issue has also been noted several times in many forums, along with the inaccuracy of the AF and the mediocrity of the X10's Image Stabilization.
Fuji definitely needs to invest more in Quality Control or else their whole 'Made in Japan' marketing slogan will become a handicap rather than a selling point.
Obviously, Fuji's tolerance settings are very different than the paying consumer's acceptable tolerance. Something to keep in mind when working out the firmware fix (if possible at all).
Higher ISO allows for better highlight protection and does make sense in high-contrast situations outdoors.Usually DR is set to 400% at ISO 400.
