When doing flight photography, my preference has been to set AI Servo\/Auto Select 19-point AF (the one that features a set of parenthesis-like brackets) and then manually select the central sensor.\u00a0\u00a0 If you are in AI Servo AF, the selected sensor will light up when you select this AF Mode. If you are in One-Shot AF, only the brackets will appear.\u00a0 Others much prefer using either the central sensor alone (via Single Point AF-Manual Selection) or AF Point Expansion (Manual Selection) for flight photography.<\/p>\n<p>The more I study the 7D and the Mark IV Instruction Manuals the more I realize how complex each camera is.\u00a0 I am hoping to offer a combined 7D\/Mark IV User&#8217;s Guide for sale at some point but that will most likely not be until spring as I have tons more to learn&#8230;<\/p>\n","protected":false},"excerpt":{"rendered":"<p> ngg_shortcode_2_placeholder Canon 70-200mm f\/4L IS lens with the 1.4X II TC (handlheld at 208mm).
