I use the 100-400. It feels like it was designed with air shows in mind with push pull zoom. 70-200 is too short in my opinion especially for jets.


I use the whole zoom range and I usually shoot in Tv mode at 1/500. Prop planes, If I remember, I try to switch to about 1/125 or 1/250 with the IS in mode 2. Jets I turn IS off.
