had the d4 and d800 set up for a while. I moved to canon because i wanted the 5d iii over the d800 for my travel camera, faster fps and better auto focus system. I got the 1dx a year later to shoot indoor sports, the 5d could do it, it just wasn't as fast as the d4. I bit the bullet and bought the 1dx- i couldn't believe the autofocus ability of it-really a step above the d4.
I did watch the same review you metnitoned (very long) on tube by two photographers that were testing the d4 vs 1dx and at the end the long time nikon user decided to go with the 1dx because the autofocus speed was in a "different class" than the nikon.
I agree with him on that. I also think the 1dx does a better job with metering over the d4.
The canon rep was in our local camera shop a few weeks back and he told us canon updated the firmware in the 1dx and they did not plan to upgrade the body.
It will be interesting to see if the d4s' new autofocus system has caught up the 1dx.
I never really understood why nikon put the qxd card format on the camera. Both are great cameras, but i think the 1 dx has the edge right now.
Interesting, yours is obviously inline with a consensus opinion of 1DX and Canon owners...but definitely not of die hard Nikon fans (I don't know any personally). It's cool that you are a Canon convert!!
In the test we both watched on youtube...I can't help but think that the respective lens's autofocus speeds played a major role (especially since they were depending on the elements going from close to distant focus, back and forth, over and over). Nikon...well they just can't make lenses like Canon, and I suspect really none of their lenses can make use of whatever AF speed ability the D4 or D4s, has. But unless someone, I don't know...tests an "identical" Sigma or Tamron lens on a D4s and a 1DX (that somehow also has consistent and "fast" AF...a tall order!), there's no getting around using a Nikon lens on the Nikon body. Obviously a third party lens is not a good way to test either camera's AF capability, so it's a bit of a conundrum.
Unless of course, you are of the opinion that Nikon's 70-200 f/2.8, is in every way equal to Canon's current "version 2" 70-200. I doubt it is, but I really have no experience...yet.
I wonder why you would favor a 5D3 as a travel body over the D800? Unless when you travel you are only shooting sports action. Usually "travel" implies vacationing...and shooting scenery, landscapes, etc...which the D800 would be superior for doing (assuming you have really long, skinny fingers, for the Nikon ergonomics).
As for the Sony card, obviously it ties in with using image sensors designed by Sony (and possibly other components too, I don't know?). They claim the Sony card is faster than CF cards, but I have no idea.
