When I use my D810 flash in “Flash Commander Mode”, I set the ISO sensitivity setting to “64” and the Auto ISO Sensitivity Control to “ON”. This should set the ISO to whatever sensitivity is needed to get the right exposure for the shot, but it doesn’t work. The ISO is always “64”. When I use the flash In TTL mode, the Auto ISO works fine.

 

Has anyone else had this problem?

As a follow-up to the above topic...

There seems to be a little discrepancy in the Auto ISO settings in both the D810 and the D850.

 

D810 in Commander flash mode @ 64 ISO sensitivity, in Auto ISO mode. Camera Info reports ISO 64.

Auto ISO didn’t work in Commander mode.

 

D810 in TTL flash mode @ 64 ISO sensitivity, in Auto ISO mode. Camera Info reports ISO 12,800.

Auto ISO seems to work properly.

 

D850 in Commander mode @ 64 ISO sensitivity, in Auto ISO mode. Camera Info reports ISO 64.

The ISO should be higher since Auto ISO seemes to haver worked here.

 

D850 in TTL mode @ 64 ISO sensitivity, in Auto ISO mode. Camera Info reports ISO 2500.

Auto ISO seems to work properly.

 

I tried to post example images but I wasn't allowed to.
