Analysis of RAW samples at Fred Miranda show weak DR

[Mikehit]

Assuming of course that you are the target population for the 6D2....and it sounds like you are not.
That is what you seem unable to comprehend.

You mean the people who are in the market for a FF with an articulating touch screen? Who don't want to carry their "pro" camera everywhere? SMH

2% of the photos in my collection are base ISO. I really don't care about it. It sounds like I am more the target customer than you are.

Most photos are not taken at base ISO everyone knows that. This focus on DR on the mk2 is ridiculous.

Maybe Canon shooters avoid base ISO cuz it's been so noisy for so long there's little point to not using 400 or 800 which actually provides good results with NR and FPN reduction...

Or maybe its because real-world photographers need the aperture and/or shutter speed for real-world photographs.

How you know this?
What is your data source?
Need be representative of all camera owners, not just CR people.

Probably because most pictures are taken in the automatic mode, which tends not to pick iso100

You are right about base ISO photo. But unfortunately 6d mk2 lose to 5d4 in all ISO range.

So it looks like Canon doesn't put the most up-to-date sensor available into the 6d mk2.

If the 6D2 sensor was created after the 5DIV sensor then yes, it is an up to date sensor.

As for the link - you will not notice any difference in DR above ISO 800. Even at ISO 400 tell me what scene you can take with the 5DIV that you could not take with the 6D2.
Now, if you are criticising Canon because of what the technological tests show and you want another 1/4 stop of DR simply because yu like the sound of it....fair enough. But in all practical terms it is meaningless.

no data, but it will be a bell curve shaped distribution, and the centre of such a distribution is not at one of the end points.....

If you look at the curves, the differences between the 6DII and the 5DIV is much less as ISO increases above base levels. Your call, but I doubt that the difference above ISO 200 would make much difference to most peoplle

The data is simple physics. ISO 100 is inadequate to get sufficient shutter speed and sufficient f-stop for all but the brightest, sunny days. I don't think automatic mode has much to do with it.

If no data then everything is guess and assumption. Not Fact.

Unless your name "Donald Trump", then anything can be fact.

You also no data, just assertion.

Everyone say which ISO popular and unpopular. But nobody got real data on ISO usage?

ISO 100 the most popular !

For every photo taken outside, I try to stay at ISO 100.
And most of these photos need/require shadow lifting.

So, overall, unless most of your photos are indoors, then dynamic range (DR) at base ISO is quite important.

Flash is getting exhausted quickly @ ISO 100.

For the original assertion, "Most photos are not taken at base ISO," would data pulled from the EXIF information of over 19 million online images suffice to adequately demonstrate the truth of the statement? Or would you prefer to argue the point further?

If you remove "Other" which might include unable to know from the Exif, then ISO 100 would be about 48% and let's not forget that some cameras start at ISO 200.
In any case, based on the Mode, Shutter Speed, and Aperture stats I suspect that's not a representative sample (despite it's size).

 

[Loswr]

If you remove "Other" which might include unable to know from the Exif, then ISO 100 would be about 48% and let's not forget that some cameras start at ISO 200 (.

In other words, the statement, "Most photos are not taken at base ISO," is supported by those data. Based on the way they report the other stats, it would seem that 'unable to know from EXIF' is excluded from the count.

In any case, based on the Mode, Shutter Speed, and Aperture stats I suspect that's not a representative sample (despite it's size).

The question is, representative sample of what? It's clearly not a representative sample of photography, since Apple 'cameras' account for ~5% of their EXIF sample. Even for ILCs, I sincerely doubt that the 5DIII+6D+5DII account for ~30% of that population. But it is likely a reasonable approximation of representative for full frame users, which is relevant to the 6D discussion.

My suspicion is that "other" is 160, 320, 640, etc, etc.... all the results that were not 100
