The possibility is there, however really unlikely. I frequent DPR forums, and we hardly ever see anything removed, thread by thread, even those that that discussed the old thread, unless influenced by the powers higher up. The removal of threads of this magnitude just isn't commonplace.

But hey, maybe they have an new and overzealous mod that is cleaning house of faked news and files! And the perpetrators are having a change of heart as well, and removed their own copies of files too, hosted on other sites. My faith in humanity is restored. :D

DPR boards are full of mis-information, yet those posts never get cleaned up. DPR doesn't administrate their board for bad info or fake info, unless influenced by outside sources. It appears you have your mind set that there is no way raw files have made it out into the wild from the myriad of 6D2 bodies that are out there, despite this happening time and time again in the past. I guess we will all see once the raw files appear once again for mass consumption. :)

responding to your edit:

Well I think I've also made it clear that I find internet forums can have false information.:-) I never made the claim that pre-production 6D2's haven't been out there, I'm just being skeptical of internet sources. You've been the one adamant that we should take heed in the internet rumors. Perhaps the reason DPR saw fit to actually mod the thread was because of the false claim of a RAW coming from them (which for any respected organization like DPR, would then have its own actions). The main difference in opinion is whether this is a front from Canon or if it's DPR responding. And finally, I think we can all agree that the verdict of the 6D2's DR will be when published RAWs come straight from the source (namely DPR and DxO). :-)

The thread on DPR appears to be back, but with only old replies? https://www.dpreview.c​om/forums/post/5981109​3 (external link) Wonder if the discussion got too heated and they nuked it and restored an older version. last I saw there was heated but not out of line commenting going on. Things can spiral out of control quick though.

Seems like I have always heard that cameras for editorial review are typically in the reviewers hands two weeks before they get in the public's hands.

Isn't 6II supposed to ship the 28th of July?

If so, that would make two weeks land last Friday ... after the files were leaked to the internet.

That's a completely different thread, asleep for a week until someone posted to it today.

None of this makes sense to me. As a 5D4 owner I fully expect the DR to be better on the 6D2....exactly the way it was when I owned the 5D3 and 6D. Logical since the 6D photosites are larger.

I will offer this info up and leave it be.

Here are 3 download links for 6D2 shots provided by a member. These were run through DCRaw as well, and the same characteristics were found with these raws as the now-removed DPR files and what Rob supplied. This is why I feel there is more reality than fantasy with what has been happening with the various raw files. Since Amazon owns DPR, it is in their best interest to make sure Canon is kept happy, and that no bad press occurs, real or otherwise, hurting their future sales. ;)

This is why Rob says he pulled his files. Keep in mind his copy of the 6D2 said "sample" and came in consumer level packaging.

These are still available, and I have them as well if the links disappear.

Use this button to download the CR2 files. Take a look and see if the files are fake or not, I have no way of knowing. Be sure to upgrade your DPP if needed. If you know how to use DCRaw and compare to 6D, cool! :D I know I don't.

Base-ISO DR has nothing necessarily to do with sensor size or pixel size. It is down to the quality of the circuits that bring the signals from the amplifiers at the photosites to the ADC.

The normal, extrapolated expectation should be that the 6D2 had a hair less base-ISO DR as the 5D4, if it used the same ADC technology. That's because when late stage noise is the main limit to DR, the only way to have more DR is to have more pixels.

To change the topic a bit, anyone been looking at the jpeg samples out there especially the higher ISO samples? I have to say if the DR topic is alarming the jpeg high ISO should be even more so. They are horrible. Totally NR crushed making everything look like plastic and the sharpness just plain sucks. Here (external link) is an example.

EXIF indicates the image was shot Jan 2014 with a 6D not a 6D2. Are you referring to the original 6D? At 1/10, even with IS, I'd say sharpness is acceptable. It was also shot in Av with -1 EC and was processed in LR 5.3 if I'm reading the metadata correctly.

This is probably not a sooc jpg. The output quality likely has more to do with the photographer's LR processing than the 6D's jpg engine.

and yet every video about 6D2 is telling that 6d2 is great low light camera and Canon is pushing low light as highlight of new 6D - is it possible that there is a problem with Raw converters because this is "not yet out" camera - i know there was a lot of problems with Fuji X-T2 Raw when he was out and even today !?!!?

I'am in such a big problem now - I just got the opportunity to buy 6D2 this friday 21.07 as a key buyer at my local photo store and now there is this DR nightmare story and all the others, I'am waiting for so long for this new 6D2 and i don't care about 4K or dual sd but I do care about DR and ISO, I want arti-screen and DP af and touch so bad but now what to do !?!?!?! and no, i can not return it if I don't like it - they making me such a favor to have it 2 weeks before ( or even more becuase who know when will I get it if I don't preorder it now ) ?!?!?

Exactly.

Those files at DPR are likely the ones that will make it into their final review of the camera.
So, analysis done on these files is fully legit.

I suspect that the DPR thread was taken down because of an NDA violation - not because of inaccuracies in Bill Claff's analysis.

Another thing to consider:
Canon already has 6DII sample images on their website, while the camera is not on sale yet.
So, are these images from a pre-production model as well ??

That was a rhetorical question, btw.

In general, the hardware specs of this camera has been locked for at least six months (12+ months is much more likely).

So, unless the analyzed RAWs are 6+ moths old, it would be naive to think that RAWs from a camera purchased at retail will show different characteristics from the ones already established.

OTOH, the people that don't trust the preliminary results are unlikely to accept the productions results either (DxO is crooked, right).
Thus, not much point in arguing about that anyway.

... and now there is this DR nightmare story ...

The 'DR nightmare story' is true, unfortunately.

Bill Claff's analysis shows slightly worse DR on the 6DII vs the original 6D.

I personally wouldn't read too much into this 0.2 EV stops difference.
For all practical purposes, the 6DII has the same DR as the original 6D.

Unfortunately, that's ~1.5 EV stops worse than the 5DIV (and 80D).
You can definitely count on that - pre-production model or not.

May I ask what led you to believe this was a 6D2 SOOC shot in the first place? Who/what gave you that impression? It would be interesting to know how this sort of disinformation is being peddled.

N.B. Absolutely, 100% clear that you had no part in this.

Well I'm prepared to wait for the real reviews to come out.

I'm sure that it's not the case but looking at your record of posting here, it would be possible for somebody to get the impression that the only reason you joined POTN was to trash the 6D2.

Just so we can know you better, what are your main personal areas of interest in photography? What gear do you use? Anywhere you can point us towards to see some of your work?

Unless the CR2 file structure has changed format, in such a way that the data is roughly in the same memory space as before, but the data is represented differently, this has nothing to do with a raw converter. The analysis was done using a raw file analyzer, and the CR2 file format/structure is known, from which locations hold raw data to the parts that hold the JPG file to the places the EXIF data resides. The analysis performed wasn't on a raw file being converted to TIFF or JPG. Again though, I have no idea what the underlying code in DCRaw is doing and how it rips apart the CR2 file, whether it is internal, or if it uses a raw engine of some sort. I do know the raw file format though, it has been published in the past, at least for the format before the 6D2.
