This Cattle Egret eating a Mayfly was photographed with the Canon 800mm f/5.6L IS, the 1.4X III TC, and the EOS-5D III. ISO 400. Evaluative metering at zero: 1/1600 sec. at f/5.6.
Central Sensor/Rear Focus AI Servo AF. Taped the pins.
The big news here is that once I worked through the chatter and acquired focus AF held nicely though the bird was walking through the grass. The next step is to try it with an outer sensor....
Don't be shy; all honest comments welcome. Questions welcome too.
