Thanks. The reason for my comment is that I was imaging ducks swimming around at this one suddenly decided to fly....it travelled maybe 30 feet or so and landed again but I was able to point the camera and fire a burst of 3 frames. It locked on instantly (albeit at very close range) and all 3 images were sharp. The system of AF point auto-switching is amazing for flight shots. That shot would have been near impossible (for me) with the MKIV. I shot pictures all afternoon yesterday. The speed of the camera and AF system are the most impressive features so far....may have to put the MKIV up for sale to offset the financial blow but I am lovin' it so far.
I also attempted some images at 600mm......no not the new supertele.....my old 300mm 2.8L + 2X TCIII. Works quite well actually. These 2 images demonstrate what it can do. These were converted with ACR with the clarity slider at around 15 but no more sharpening in post.
These are both full frame images (uncropped). The light was quite good so the 2X TC may not perform as well in poor light but these look pretty good to me.
Of course with the 600mm lens you would have the option of adding the TC's and get even more reach. Anyway, just a little more 1DX info for those interested.
