I had a quick play with the 1DX at the Canon Pro Solutions show yesterday. Absolute monster.  I wish I could get 100% crops showing noise comparisons the best I could do was take a friend who is a D3S owner.  Going purely by what we could see in the LCD (no memory cards allowed I should have taken the laptop and plugged it into that! And I don't know if the jpg preview on the lcd has noise reduction on or how much) the 1DX at 51k ISO  outperforms the D3S at 12,800.

As for video, I believe each recording mode includes an option to make all frames a keyframe.

I was told by a rep there that the 200-400mm, to his knowledge, is in prototype stage only and might not even actually make production.  This contradicts a canon rumour post from today.  Personally, since Canon had a 200-400mm mock up in a cabinet which was always surrounded by punters asking about info on it I can't see this not making production.

if one looks at every generation of even crop camera's, there is typically about a 1 stop gain in each generation increment. My 40d for example, compared to a 60d.

Fullframe Im sure on this body will easily do 2 stops better with the massively significant changes they have made to signal processing and sensor design. 51k may not be super usable for many people, but for some it will. One also shouldnt ignore how amazingly good noise reduction in lightroom/photoshop have become. ISO is always a compromise, but if you really need to nail a shot in the dark, I doubt theres better than this 1dx or d3s.

Some other comments from the London show

Chris Miller shared some of his thoughts about using the 1D X at the show yesterday.

No cards allowed, but he was able to make some (limited) image quality observations

In other comments I've heard, it seems that the Canon people were asked quite often about whether the 1D X was 'really a 1Ds3 replacement' - no revealing answers  I'm afraid... :-)

For high ISO low light shots most noise is photon shot noise and is unavoidable, it is a physical property of light.

However, the indication that there may be visible pattern noise (read noise from the electronics) worries me, this is a killer concerning useful dynamic range and has been a problem with Canon cameras, for example the 5Dmk2. I really hope that Canon can do as good dynamic range as seen in Nikon's (Sony's) newer sensors, which do not have any significant pattern noise problem.

LOL, you know it's an Engadget "review" when commentators inevitably compare the product to their iFruit. Nothing new here, move along. Pre-production firmware makes the high ISO observations useless at this point.

Having now had a play, I can comfortably say the ISO really is something else, the AF is also something else. Ergonomics a nice improvement and that gigabit connector socket is not to be sneezed at. Several other features, but I'll leave it all for my blog :-)

Can you post other things like:

- How is the shutter/mirror sound in comparison with older models? (louder etc.)
  What options do we have WRT this?

- How heavy is / feels?

TIA

Here is the link to my post on both items.

Regards shutter/ mirror noise - it was no louder than older models until you ramped it up to the 12/ 14fps. Then i think the speed of operation just couldn't be overcome. That might be a hindrance with wildlife, golf and tennis, but nothing else. So little did i notice it, i forgot to put in in my review - i was just impressed by the fact you could - and for 10 seconds.

Shutter options came in at single, low speed multiple shooting at 6fps (maybe 7) and hi speed shooting at 12/ 14 fps.

Weight is covered, slightly heavier than a 5D2 with battery grip, but improved ergonomics over come this.

Thanks Andrew for the review and for the clarifications!
One more: Are you just saying that you can leave the AF system 'alone' to choose the subject and track it, without back/front-focusing and/or choosing something else?

pretty much.

The trick is the large number of genuine cross hairs - 41 of them. But the real boost is those new additional double cross hairs. These include the usual '+' type of cross hair, but now also include the 'x' cross as well.

This is what really makes the lock so strong. Double the ways of keeping the intended target locked while it is moving. Of course, i couldn't get any one to run around or weave like a footballer, but the speed at which the camera just locked on every thing was just astounding. I was using the 'right cluster' (that is the best way of describing it) as i panned round the hall. Had about 20 focus points in it. The focus points lit up and went out light christmas tree lights and beeped merrily away - hence my statement that 'if their had been music they may have beeped to a rhythm'

But the strangest thing was - they didn't seem to get in the way of the seeing the subject. That was really strange, so much more unobtrusive than the 1D3 AF system.

Must remind you that with AI Servo, the trick is to lock on to the right subject in the first place, but once locked...
