Great article, especially the undocumented features. I need to try this but theoretically if you enable orientation linked af point you should also be able to set independent af-on settings for portrait or landscape mode...that is have two selectable zone af points in portrait mode and zone af and 61pt in landscape mode.
I tried and used orientation linked AF point but the thing is that sometimes you change AF mode setting (e.g. from Zone AF to 61pt AF) in landscape and these changes are then not in effect when you switch to portrait which becomes kind of frustrating and very complicated - so I stopped using it.
And you can further customize your use modes by recording your ideal BIF fast action settings to custom mode 3 at the end of the mode dial. This will let you switch to this mode quickly without looking and will also save all of your customized settings....one may actually want to use different af and af-on settings for shooting a wedding or portraits or even bif with a different lens.
Yes, that's exactly what I do. C1 is my action mode. You also said to leave AF case 1-5 in their default state and use 6 for BIF settings - a good idea but not even necessary because when you save your settings to C1 and then
overwrite AF case 2 while inside C1 mode
, case 2 will only be overwritten in C1 mode and not in Av, Tv, M etc!
Thanks for your input!
