Re: Is auto ISO fixed with fill flash?

Hi Kev The Doc,

Thanks for the hints. Raising the max auto ISO value considerably confirmed your observation that it uses half that value as the maximum ISO. The histogram showed a better distribution, however the high ISO values lead to more noise (ugly in black fur) and more influence of ambient light (moving puppies have some "ghosting" effect of motion blur combined with the flash exposure)

In short, the problem is: not enough light. Either the A77 solved this in a better way or the Metz 58 AF2 was more powerful than the Godox (despite the specs).

For the time being I'm experimenting with one of the old Metz flashes in slave mode. Maybe I'll see if there is a better way to let them work together but currently it seems to work fine just in the optical slave mode where it fires as soon as it detects a flash.
It looks like the Metz flashes at full power and the Godox adds whatever light is necessary for the scene.

Thanks for the clarification.
