Interesting, the first youtube clip was shot whilst i was standing at the counter trying out a 1DX.
Whilst they are interviewing the gentlemen who has just bought the 1D4, i was standing behind, to the left of the 2 gentlemen who are located in the right of the frame.
Their interest was very much about the video qualities of the 1DX, and they were happy to pre-order.
My interests were very much about the ISO, the focusing & ergonomics.
The Dual CF and Gigabit ethernet ports were very much matter of fact, but holding it and trying it at extremes was what i was about.
In respect of 'why they keep pushing' the 14fps - is because it is a whole new mirror mechanism that is what has facilitated the excellent video moire that they keep talking about. The 14fps is a side effect, but a welcome none the less.
My take on the 14fps is - use it like 204k ISO - when you absolutely have no choice.
For wildlife - they will be gone after frame 6, your hands will feel like they're holding a hammer jack after a few seconds. It is noisy and it creates some vibration - but if you have a high enough shutter speed, you will over come it.
As for whether or not i'll get a 1DX, the answer is, i'm already doing my sums and working out what i need to do to get one. 1DX with a 5D2 as a second body should keep me happy for a few years :-)
