I've just come to the attention that some generally shoot zone AF. I'm a Canon and Fuji shooter and I've selected my Canon tools for hired events and my Fujifilm gear is generally used as a secondary system for personal projects, family documentation and casual.
A fuji shooter has made it to my attention that he uses zone AF over selected auto focus points. I've been vocal regarding the slower and sometimes unreliable AF performance of my X-T2 (even with Battery booster) in low light for events documentation. The AF has virtually failed on me on many occasions during spontaneous events or when using bounced flash techniques in low environments/venues. Mirrorless does not take advantage of infrared focus grid on speedlights like Canon or Nikon. I was informed zone AF is more suitable but this leaves the camera to decide my focus points. Such techniques is a big shock to me. I choose my tools specifically for many reasons. This is probably why I still cannot let my Canon gear go.....one the same note I do like fuji render too.
I've never ever used zone AF for events and probably never will.
Just out of curiosity I'm making this poll. I've honestly ever considered Zone AF for birding/fast moving subjects while panning or just quick AF acquisition with longer lenses but not short fast primes or mid telezooms for human subjects in social gatherings.
I think a poll is quite cut and dry. Please note this poll does not apply to Sony A9 users LOL!!! The eye tracking on that sony body is absolutely insane. However for multiple people in the frame eye detection can be risky in my opinion.
