Christian – Yes, indeed. That is one of my new favorite features on the GFX 100S!

Jeroen – Hello. Thanks for the nice comment. As I said in the article be aware of what lens you are using as some are slower than others–all of the GFX zooms are very fast. Some of the GFX primes are a bit slower and hence for faster moving subjects I choose the appropriate lens (for focus speed) as well as focal length. As for my settings, I just leave the “Face/Eye Detection” in “EYE AUTO” mode 99% of the time. I don’t really use “Face/Eye Detection” for tracking anything that is moving–only for portraits where the subject isn’t moving. If the subject is moving I use a larger square with the “ZONE” or “WIDE/TRACKING” modes and adjust the “AF-C CUSTOM SETTINGS” to match the scenario. Also, the “Zone Area Switching” varies depending on which option you choose in the “AF-C CUSTOM SETTINGS”. I also use a smaller depth of field to give the AF some cushion as well when shooting fast action. I think the key thing to remember is that the GFX cameras have a much shallower depth of field at any given aperture compared to smaller sensors so f/5.6 can still be pretty shallow depth of field with action. I would suggest testing it out on a variety of subjects and seeing what works best for your use case scenarios. Hope his helps.
