Does Canon *min.* autoiso range work on older cameras?
« on: August 27, 2013, 01:06:26 PM »
Though older cameras like my 60d only have a *max.* autoiso range setting in the canon fw, I just discovered that the min part doesn't contain junk or zero, but actually the setting that is used - iso 100. Could it be that Canon uses this value in their fw, but just didn't provide an ui frontend for it? If so, exposing it would make a great addition for the ml expo menu!

Did anyone try to *set* this value yet (I'm a little hesitant to do something like this, even in C mode, since I cannot afford to brick my camera)? This is how it's read, the same as on 5d3/6d:

Code: [Select]
int canon_min_iso = auto_iso_range >> 8;

I thought all of them had a min/max for auto ISO just not sure if its used if its not in the front end... ie you change it and nothing happens. Its a memory location and not a property so assuming it would be fine.
