Roland Karlsson: So. No motor? And how do it glide? And can you adjust the speed?

I just checked out the website and looks like I'm wrong. No springs, but there is friction adjustment, similar to a Video tripod head.

I'm guessing that it's spring loaded, given the arms are quite fat. Speed adjustment would then be possible by tightening or loosening the hinge mechanism. So you probably have to push the arm to the other end first and then it will travel back the other way on its own.

Ktrphoto: Can someone tell me, what is the point of showing how poor the images are when you try to recover from 5 or more stops of underexposure? It is not something that is likely to influence anyone's decision on whether to buy this camera or not.

It might be relevant for a camera aimed at the general public, who, a decade or two ago, were saved from their exposure errors by the latitude of colour print film.

But this is a camera for professionals and skilled amateurs and they don't make a habit of messing up the exposure that badly. I am much more interested in the IQ when the exposure is correct.

I don't really buy the argument that you need to be able to pull detail out of areas that are 5 stops underexposed either. Two stops maybe.

You can see hints of noise in the shadows in the sunset tulip photo done by DPR of the 5DS which was post processed, even without pixel peeping. Better DR would surely give less noticeable noise. http://www.dpreview.com/reviews/canon-eos-5ds-sr/11

marcio_napoli: Is it me or the crop sensor D500 beats the D810 on DR ? :O

Depends on what part of the test shot you're comparing. Comparing the shadow next to the bottles the D500 does better but comparing the 4 portraits, the D810 is better.

Yay for Pentax! Are we looking at the next phase in digital cameras? Pixel shift tech gives even better sharpness than the 50MP Canon 5DsR. Even the silver coins retain their circumferential dots. Let's not also forget no more aliasing and moire (as far as I've found).

elave: I would like to see real world results. Because this high precision tools are almost like industrial equipment. You can appreciate cost benefits only by comparing them in real world. Still from a technical point of view the review is as complete as a lab tests can be.

Quite likely they will have real world shots too, as per Nikon D5.

indusbreed: Bringing A7rII into the equation is fine but was not necessary. D5 is the direct competitor. Might as well throw some Phase one images there as well. A7 R II is no doubt a brilliant tool, but for all intended purposes, its the odd tool out here.

Please do some real world tests as well.

Sorry, deleted.

BokehFanatic: Can somebody explain to me why we would need to push images +6EV? Personally, I've never done more than +2EV, and in most extreme situations +3EV when considering bumping up the shadows. That begin said, it's nice that Canon has great progress on this regard, finally!

However, the D5 has a full stop high ISO advantage to me, and I'm pretty sure 95% of the 1DX/D5 users care more about that than the dynamic range.

Sometimes it's because you've got both underexposure and shadow lifting to do. Might not be used very often but still good to know the DR limits.

Time will tell as to the ratio of sports shooters preferring more DR or better high ISO. Much will also depend on how well the noise can be cleaned up.

D Gold: Just an observation...

Set it to raw, load the D500 in the next window. The two cameras look identical noise-wise as you go up the iso scale. Then the D500 gets better above 102400 .

And D500 has a powerful AF that probably yields more in-focus frames.

So a 3 fps advantage for $4k more over a D500? Looks like this new Canon is mainly attractive to pros with lots of Canon L glass.

How about comparing the 4 portraits? In sports photography, faces are still important aren't they? Even if you say the D500 is better at ISO 200K, it aint all that pretty.

Mikael Risedal: well done Canon

That's an odd comment coming from you :-) Not being sarcastic right?

Favorable Exponynt: Maybe reviewing these kinds of camera should be left to people who actually work day to day with these monsters (recognizable by their big fore arms). I bet they don't whine about minor dr differences.
They would care much more about the drastically better battery life of the D5 compared to 1DX mkII (3780 vs 1210 cipa rating) that is more than a 300% difference. What has Canon put in there? Can you clock down the Digics? Or disable one of them to save battery?.

And you know this how?

I don't see the D500 better at all at any ISO. Either on the Full or Comp setting.

Thanks for the latitude tests DPR. DXO gives us the ratings, but you give us actual images to compare side by side, including options for 100% and equivalent size.

After generations of promises of better dynamic range, Canon finally deliver a nice leap from the 1DX2 and 80D. It's been a good wait for the 1DX2 results since announcement.

It really does look like Canon and Nikon have traded sensors for their flagship cameras. Canon now with more DR, Nikon now with better high ISO.

munro harrap: I try but fail to understand. I try hard, I still have my 1DsMkII, but fantastic though it is, it is used little, replaced by the D800. Now why do Vanon continue with these 18-22MP full frame models at all?
IF you want fast frame rates and prefer accidental timing to your own choices, anything much cjeaper will do, and is all you deserve, but I want a 50MP 1Ds with the same 0.042msrc lag my 2004machine has. Not some obsolete low res machine, as I have got one already.

Is the 5Ds shutter lag so bad? If you want 50MP without the high frame rates, that's your camera.

Perhaps a reversion to off chip ADC?
Just wondering if on chip ADC and deep buffer causes heat problems.

toomanycanons: OK, better than before but still more noise than a D7200. Also, compare for yourself the Canon 6D against the Nikon D750--I never knew the 6D had such limited ability to bring up shadows!

Obviously the 6D is limited by some old tech. All Canons before 80D had the same DR of 12EV or there abouts, regardless of full frame. New tech cracks that barrier. Good thing we don't have to wait years after the 1Dxii for the tech to trickle down to a consumer canon. It's been too long already.

In reply to:

stevo23: And yet, Nikon D7200 still looks significantly better.

We'll take whatever improvements they give. DR has been hovering around 11EV and 12EV for yonks.

We've finally cracked through the 12EV or so DR ceiling. A red letter day for Canon. It's quite strange Canon took so long but thankfully we're here now.

On article Canon updates firmware for EOS-1D X and EOS-1D C (33 comments in total)

Yay! to intelligent photography. Why did it take so long? A red letter day to the Canon faithful.
