Hi Gary
Congratulations with your 1DX, and the 'super' lens... what a great combination.

I appreciate your sample photos, beautifully natural and lovely compositions of wildlife. These are the sort of photos I like.
Gary, do you feel the AF is 'best you have ever used'? How would you compare it to other Canon DSLRs you've used? (I have a 7D and have managed to squeeze out lots of good photos, including bif).
I'm sure the 1DX is obviously superior to the 7D in every way.... but just good to hear your thoughts and see those sample photos.

Neuro.... yes... keep repeating to yourself.. you must.. keep strong... for all of us...

Cheers!!
Paul
