To answer some of the questions above.
I was waiting until Sony gave uncompressed RAW as a option before taking the plunge.
To answer someones incorrect statement!! YES I am very heavily invested in Canon L series lenses as you can see at the bottom of my posts, if you had bothered to LOOK :
& do I really need to explain uncompressed RAW Here?
Yes the 1DX is the wrong camera for me NOW at this moment in my life (it had not been until a Year ago).
I have already given my 1DMk4 & an 600 EX speedlite to my son & I will be giving him the 1DX as well, along with a heap of L series lenses & another 600EX.
The reason for all of this is simple, I can no longer hold them for more that a couple of minutes because of the weight & I am getting weaker as the months go by, as I've been diagnosed with MND (Motor Neurone Disease). The Sony A7R II with its FF & now uncompressed Raw plus being very very light weight will allow me to continue doing what I have enjoyed all my life photography! (I'm now 69) for what ever time I have left on this planet.
Whilst the 1DX is without doubt the best SLR available for sports or studio work, the Sony A7R II runs it very very close, maybe not for Sports photography but I don't think I will be doing a lot of that now in my condition.
Had Canon got there arses in gear when they had the chance with there own mirror-less camera (instead of the pathetic M series) I would have almost certainly bought Canon again.
yes I will miss the simplicity of the 1D series cameras & there ability to change settings very easily plus all the other features they have like full waterproofing etc etc, but what I shall really miss is the security of the Canon CPS service backup :'( , as that is second to NONE.
Tiltshift YOU were spot on with your comments
my man.
