I would like to understand more how the “Focus with filter” in the filter setup tab works with the ‘auto focus with filter’ on the focus settings tab and “auto adjust focus per filter”.
For instance - if I set Lum, for a narrowband filter in the ‘focus with filter’ tab (in the filter setup) with ‘auto adjust focus per filter’ set, does the AF use the Lum and then offset?
Or, put it another way - is there a setting combination that would achieve the following:
- Autofocus for wideband filters (LRGB) use its LRG or B filter for focusing
- Narrowband filters use Lum for AF, and then automatically offset.
There is an interplay - which I think is only partially explained in the help file and I am not entirely sure of what overrides what.
