Steve, thanks for posting the highlights as well as the details. Adding the bird AF is welcomed as is the af mode cycling feature. Now the big challenge will be figuring out how to optimize the function and reassign all of the buttons. Currently I have the shutter assigned to one AF area, the BBAF to another, and a fn button assigned to spot. Do you see any wisdom of keeping multiple buttons assigned to individual af modes or does it make more sense to just assign the cycling to a fn button which could work while shooting? No it doesn’t offer an override, but if the af has improved that significantly, and one can switch modes near instantaneously, is the need to handoff as pressing?
