Analysis of RAW samples at Fred Miranda show weak DR

Neuro, Bill was upfront that this analysis is only preliminary and far from being final.

Those curves are from Bill Claff (PhotonsToPhotos.net) who is very respected, so they should be taken seriously.

Actually, my respect for Bill dropped a notch with this analysis of a leaked RAW file from a preproduction camera, with potential unknown (and unknowable) differences from the production units not yet available.

Yet we have reports from France of the same performance as the 5D4.....

There is too much noise from too many trolls.... too many rumors discussed as if they are facts.....

Wait until someone reputable takes a camera off of a retail shelf and tests it properly......

Until then, all is noise.....

I agree that Bill's data is appropriately caveated. Being first out with information is irresistible and appreciated by many. One step beyond rumors. Most have assumed that the sensor implementation in a 6D II would be of the same DR class as 80D and 5D4, but this new info is reason enough to question that assumption and at least give a moments pause to those considering a pre order. So, in that sense it is a service to potential buyers. A month of patience and the final data will be available for all to kick around.
I'm now thinking that the 6D II will have the effect of increasing 5D4 sales. Clever

Nevertheless, he drew a conclusion and supported others who have drawn the same conclusion.

Bill is smart enough to know that his data will be disseminated without any reference to those caveats.

I agree with you. I would do the same.

There's a reason actual journalists triple-source and don't just go repeating something they heard from some guy on the internet. It speaks poorly of him, no matter how he couches it, because as we can see, people are taking it as the gospel truth despite that disclaimer. And he must have (or should have) known they would.

So DPR has become DRP = DR Preview.

Well, Amazon's rising star Rishi will be along any day to tell us how poor the 6DII's IQ is, compared to its 'best-performing peers' like the D810 and a7R II.

I realize that you have a thing for DPR, but to be fair, all they have done in this whole tempest in a teapot is repeat a statement from Canon. It is others who are stirring this up and making mountains out of something that doesn't even quality as a molehill.

I'm with Neuro here. At a minimum, a clear 'Potentially Pre-production Model' next to the 6D2 listing in the legend was in order.

Notes:
Canon EOS 6D Mark II measurements are estimates pending complete results.

Putting that in red right under the chart is not enough? He posted pre-production estimates for the A9 also, with the same sort of caveat there.

No, it's not, because this happens:

People can just forward the chart without caveat. All we have to see is a footnote marker "(e)" in the legend.

Think about this from the chip designer's point of view...... Canon is shifting ALL sensors to a finer fabrication line.... they have had to redesign their sensors to fit, and EVERY other sensor so far has the ADC on sensor and has greatly improved DR.....why would the 6D2 be different? Canon would have had to deliberately designed an inferior sensor for this model only, knowing full well that it would impact sales and profits..... That's right, they would have had to have made an additional expenditure of money and resources in order to deliberately sabotage their best selling FF camera knowing that it would cost them even more money, and at the same time, drive people to the competition..... not very damn likely!

I have a real hard time blaming people reporting on things for the chicken littles of the world

The internet does not have any standards for truth or excellence. Most of us understand and accept that. Use it for good or ill as you will.

A sign of the times; we're in Trumpland. A certain minority will always enjoy trashing anything for a lark or for a misguided conviction, after all we see examples in the news daily.

Here we have the world's most amazing cameras in all of history and folk want to diminish them to equivalent to trash (whatever brands), in spite of the amazing photos that we're seeing from amazing photographers using them in recent years. Almost amusing but actually sad to think that I might excuse my crummy shots in this way if I purchase a 6D2. I've loved the 6D and the new version has lots of upgrades and I'm now to believe it'd be trash in my hands?? :)

And, in my 4 years of 6D I've shot probably 75% at ISO 1250 (mostly wildlife). For me higher ISO capability would be great since I never seem to have enough light out in the bush. It's higher ISO capability that is making me appreciate having the 1DX2, heavy beast that it is. Never imagined I'd be able to live such a dream in the latter years of life.

I have an easy time blaming people who use the veneer of journalism to lend credence to "some dude on the internet said this, so I'm going to 'report' on it".

When it's someone on FM it's someone on FM. When a "respected" site repeats the claim, suddenly it appears much more legitimate. This, again, is why journalists are supposed to multi-source and verify.

Agree 100%. I believe most of us here were assuming we'd see the 13+ EV DR (+1.5-ish EV bump over the prior model) that the 1DX2 / 5D4 / 80D all demonstrated, so no, this makes no sense at face value.

Neuro is quick to point out the D5 experience, where it appears Nikon abandoned base ISO DR opportunities (I believe to pursue better performance at high ISO). But why Canon would deliberately do that as the start of their FF portfolio after just updating two other FF models differently makes very little sense.

My money remains on this being a RAW file from a pre-production model. It may have been properly analyzed -- the PtP person is not without cred -- but the file may not be the final output people see with their production 6D2s.
