Canon AF Settings for Birds in Flight … an illustrated e-mail Guide: $10. Free with proof of purchase of any BAA Camera Users Guide.
As most of you know, I struggled for years with choosing which AF Area Selection mode to use for birds in flight, which AF point to select, and what settings to use for the three parameters in the case settings. Ironically, right before I switched to Nikon I tried something new and found that it worked like a charm. I was able to get sequences of sharp flight images with both my EOS 5D Mark IV and my EOS-1DX Mark II camera bodies.
