Hey Jan


This was my set up at 2 air shows this year. I must have seen at least 15 people with the 100-400.


I don't think you can go wrong with zones, I used AF Expansion just because it was set there from shooting football.I use Servo and highest frame rate.Even at 8 frames I miss the the Thunderbirds crosses.Since everything is left to right, for the most part, and pretty far away I don't think any of the exotic focusing custom settings are necessary. C.Fn III #1 you can adjust servo tracking sensitivity. Mine is set to fast It may not matter due to the distance you are. #3 might be good to set to Continuous Track, incase someones head passes in front of the lens. #9 will turn on all the AF points. AWB will kill you FPS so set it accordingly.


My rule of thumb, if I'm shooting jets Av @f/5.6 (under DLA) ISO 400, IS off. For props I use Tv 1/400 (+-) ISO 100 and IS mode 2. ISO 100 usually will keep the f/stop around the DLA point. You could use a ND filter, but I don't think it will be necessary.
