1D X ISO Shots

[neuroanatomist]

There are quite a number of other differences between the 1DX and the 5DIII, but none of them are any more significant to real-world shooting than the noise difference we see here.

Depends on your definition - if you're talking only IQ, fine.  But...better sealing and 250K more shutter actuations seem like they benefit real world shooting, not to mention the improved metering.

I would say there is marginally less noise in the 1D X, but nothing to really use as a reason for going with the 1D X and only visible side by side. However, to me, the colour reproduction is better in the 1D X, as the MkIII has a slight yellow tinge. Again though, that would be easy to correct and could be done with a preset to save time. Most probably wouldn't benefit from the 1D X, but those that need the features (e.g. weather sealing, speed etc.) would happily pay the extra. AF accuracy may be similar, but the reported increased AF/tracking speed of the 1D X could be the difference in getting the shot, which alone would be worth the extra to pros that have to rely on it to get the shot.

Basically, the 1DX is a speed demon. 12 FPS and unsurpassed autofocus performance.

There are quite a number of other differences between the 1DX and the 5DIII, but none of them are any more significant to real-world shooting than the noise difference we see here.

Unless the 6 FPS of the 5DIII isn't fast enough for what you're doing, there's no reason to spend thousands more on the 1DX. But there are those for whom 6 FPS is painfully, unusably slow, and their biggest problem right now is wiping the drool off the back of their sniny new 1DXs.

I'm just wondering when we'll see the 1DXXX with its 24 FPS framerate and buffer limited only by card space...imagine what the cinematographers will do with that!

Exactly.  I think the IQ and ISO is similar, the next logical thing to do would be to take some low light action, or just any sports for that matter.  Unfortunately my first football game isn't until late August.  But that really is where things will show up.  Low-light, real photography, with action.  I'm guessing these photos will show the advances of the 1D X.  I have a night football game in late August, but that's the best I can do for low-light sports, and the soonest.  If I can find a sports event soon, I will.  I am going to a car show this weekend.  I will shoot the car show with both cameras and process in post as normal, everything business as usual, no RAW files being posted, and do a real-world comparison.  I think that would be the next most meaningful step.

The 5DIII already has plenty of sealing, more than enough for most camera owners. Not many people will find themselves in situations where the 1DX is adequately sealed but the 5DIII isn't. Some, but not many.

And not many people will wear out a 5DIII shutter. Those few who will are going to be CPS members and aren't going to notice the $250 or whatever fee to repair the camera plus the day or two it takes to get a loaner while the one is in for repair. They're not going to notice, of course, because it's one of many backup cameras they already have for exactly that sort of contingency.

If the metering on the 5DIII were problematic, you'd have a point...but, again, the 1DX is better while the 5DIII is just fine.

Just to reiterate: I'm not trying to claim that there's no difference between the 5DIII and the 1DX. Quite the contrary. My point is that, except for the fact that the 1DX is an unbelievable speed demon monster and the 5DIII is merely not pokey, the differences are fairly minor, especially in the real world.

And, to continue the theme: most people don't need an unbelievable speed demon monster and so don't need to spend the significantly extra money on the 1DX. That's especially since, in the film days, the 5DIII's 6 FPS would have been considered reasonably fast, and even (barely) adequate for pro sports. But you'd probably lose your job if you tried to cover the Olympics for SI with a 5DIII instead of a 1DX, and rightly so, and those're exactly the sorts of people who should be snapping up the 1DX as fast as their credit cards clear the bank.

To add on, I don't think Canon intended there to be a huge difference between the 5D3 and 1DX.  I can appreciate the strengths of both.  I think the real comparison would be the 1DX vs. 1D4, which the 1DX was intended to replace.  I'd be really disappointed in Canon if the 1DX blew the 5D3 out of the water with regards to color, metering, and IQ.  What you are paying for primarily is the speed.  If I wanted AF-point spot metering I would have just kept using my 1D Mark IV.  Since I'm doing college sports this year, I'd like the speed.  Just as a disclaimer, that's the reason I personally bought the 1DX.  I knew going in the IQ was not better than the 5D3, and it isn't.  I agree that if you don't need the speed and AF-point spot metering, you really would have wasted your money over a 5D3.  If you need the exceptional speed and want to enjoy 1Ds3 or 5D3 IQ, it's the way to go.  You have to decide if the extra speed is worth double the price.

We'll find out however, with more testing.

Good thread so far. I like these real world comparisons of yours. The "real difference" between an 1Dx and a 5D3 imo is this: The 1Dx is the extreme photopress workhorse. While the other cam is the top allrounder body. That's why I go for one, and because an 1Dx is way too much money for me. But I am sure I'll have plenty of camera for a long time. Shooting a 30D the last five years...counting a little more than 40k exposures...Purchasing the cam at my 48 years, the 5D3 will do for quite some time, concerning an amount of 8k exposures per year ;-) And it will allow me to do all these low light shots at almost no light. First I'll do is to try out my 50 f/1.4. Hope retail price over here in Switzerland comes down a bit once the christmas carousel gets started...

... compared to the silent mode of the 5DIII, the 1D X shutter sound (even in the nominally silent mode) is loud!   

Yes the 5DIII silent mode is eerily quiet. That rowdy 1DX shutter may be the price we pay for 500,000 actuation robustness.

The new metering in the 1DX has really impressed me so far.  I still have a D4 lying around and over the week-end I played taking the same shot with both the D4 and then the 1DX (inside shooting) - not a real test but just real life shooting... There is no doubt that both metering system are "tuned" differently.  However all the "WOW" pictures I got were from the 1DX.  Not only is White Balance much improved from the 5dmkII but there is just something about how the 1DX capture light and adjust the exposure to make some spectacular shots.  In comparison the Nikon metering seem to produce more flat pictures...still very good...

My point was not to make this comments about Canon versus Nikon metering, but just using reference points I have/know since I cant compare with the 5D mkIII...
