Panasonic did something special with the Z6 III sensor

I think the whole topic of a lack of dynamic range for Z6 III is overblown.
Perhaps, although some believe that even discussing the camera's dynamic range at all makes it "overblown".

One observation...debates about what represents adequate dynamic range only seem to come up when discussing a regression of dynamic range performance in a new camera model. I hardly ever see it debated when a new model makes an improvement to dynamic range, even though the improvement itself is still discussed.
I think it’s mainly overblown because at base ISO, DR is about the same as the Z8 at that same ISO value, and nobody ever complained about that camera to the same extent. So it’s rather selective there.
The maximum DR for cameras is at their base ISO
True, but sensor performance should be compared at the same ISO values.
Try to get away with that restriction in an equivalence thread :-)
and the Z8/Z9 have significantly greater DR at their base ISO of 64 than the Z6 III does at its base ISO of 100. And there was a healthy amount of discussion about the Z9's DR when it came out.
I don't seem to recall that, but it is interesting that the DR of the Sony A1 (according to Russ and Loz) is "in another league" compared to the Z8:
. Their sensors seem so similar.
I don't know who Russ and Loz are, but Bill Claff has the data showing the two cameras have the same DR at their respective base ISOs. The A1 has about a 1/3-stop advantage in general across the board.

The question that's too often ignored in these discussions is, does having a lower DR make a camera unusable. When the Z6III came out, people were losing their minds over a peak DR of 10.44 stops at ISO 100. To put that in perspective, I shared that for years I'd been photographing wildlife and birds with a Nikon D500. I would typically use an ISO of 400 to be in the camera's invariant range. The D500 has just over 9 stops of DR at ISO 400. That's more than a stop less than the Z6III at its base ISO and the D500 makes gorgeous images with those 9 stops.

We're photographers and we'll always welcome more dynamic range if it fits within our creative goals for a photo. As Horshack has documented, Panasonic has applied a technology allowing a fast action, high data rate camera to not pay a significant price in DR at base ISO to achieve that data-crunching nimbleness. That's a good thing and I would welcome it in future generation Nikon cameras.

However, let's not lose sight of the fact that great photography can and is being done with exposures so weak that a camera's DR is in the 6 and 5 stop range. That's like 3% of the DR of the Z6III at base ISO, less than that if the reference is the Z8 at base ISO.

The bottom line is this: if a person can do outstanding photography with a Z8 or Z6III, it's not the camera's fault.
 
...

One interesting clue for at least the sensor readout method is the fact that Panasonic's implementation increases the readout time by approximately 2.3x times.
Does the longer sensor readout lead to greater rolling shutter? From the way I've understood what you've described, it sounds like it would.

If a camera supports a lower ISO than a competing camera then that camera has an advantage over the other camera. Why should that advantage be discounted by comparing only common ISO values?
That’s the difference between comparing cameras, and comparing sensor performance.

They are the same core sensor, based on their identical readout speeds after normalizing for their slight post-crop sensor row count differences.
I wonder if differences in the CFA might be responsible for the observed difference. A less restrictive filter lets more light through, though color accuracy could suffer as a consequence.

OTOH maybe it’s just different processing downstream?

Not sure what you mean. When you want maximum dynamic range you use base ISO. If a camera/sensor has a lower base ISO then you use it to get that camera's/sensor's maximum range. This thread is entirely about dynamic range.

Exactly this. A very large majority of my ISO 100 shots could have been shot with a marginally slower shutter speed without any real drawbacks. Those were shot at ISO 100 exclusively because that was the absolute minimium of my camera.

If you can drop the shutter speed. Now we’re into use case. Maybe you want a slow shutter speed and that’s fine. Or maybe you have so much light available and/or shoot with a very large aperture, that you don’t worry about it. All I’m saying is, I use ISO 100-800 too.
If a camera/sensor has a lower base ISO then you use it to get that camera's/sensor's maximum range. This thread is entirely about dynamic range.
If this is the definition of dynamic range, then ok, but then it does have an impact on use case.
 
True, but sensor performance should be compared at the same ISO values.
Generally speaking for the kind of sensor in the Z6III, increasing ISO decreases DR at the highlight end.
I never understood DR “at the highlight end” or “at the shadow end”. I think you’re talking about the curve being applied either in camera or in post to interpret the RAW data?
So increased DR is only usefully deployed when you can increase your exposure (ie. lowering shutter speed, opening up your aperture or adding more light) in order to collect more light. Comparing sensor performance at the same ISO doesn't matter here because of that: you want more DR, so you're going to have to increase your exposure in some way already. It would matter if the ISOs had different gain settings, for example.

IOW, you can't say that ISO 100 would have let you use a faster shutter speed to better freeze action (for example) and ISO 64 would force you to use a slower shutter speed, so you can't compare the two ISOs. In order for you to get more DR at any ISO, you have to increase your exposure in some way, so if ISO 100 gave you the same DR as ISO 64, you'd have to use the slower shutter speed there as well.
Sorry but this is not making sense to me. It feels like you have an opposite understanding to me. Of course a lower ISO would force me to use a slower shutter speed for the same exposure (assuming the same aperture as well).

That’s fine, but now we’re talking about use case. Like maybe landscape photography on a tripod where shutter speed doesn’t really matter because nothing moves. Except maybe clouds or stars, and maybe that’s the whole point.

Maybe I should have added “for the purpose of this discussion”.

I linked the video. Though they are just photographers and his observations are based on using the camera.
The question that's too often ignored in these discussions is, does having a lower DR make a camera unusable. When the Z6III came out, people were losing their minds over a peak DR of 10.44 stops at ISO 100. To put that in perspective, I shared that for years I'd been photographing wildlife and birds with a Nikon D500. I would typically use an ISO of 400 to be in the camera's invariant range. The D500 has just over 9 stops of DR at ISO 400. That's more than a stop less than the Z6III at its base ISO and the D500 makes gorgeous images with those 9 stops.
So now we’re talking about “DR at ISO”, which seems to be a different definition from what others are using. Though I agree that this is useful to talk about as well. After all, the fact that you don’t gain any more DR when lowering the Z6III ISO from 100 to 64, means that, unless you’re losing highlights, you should shoot at ISO 100 or higher. Because then your signal to noise will be better (stronger signal compared to the noise).
We're photographers and we'll always welcome more dynamic range if it fits within our creative goals for a photo. As Horshack has documented, Panasonic has applied a technology allowing a fast action, high data rate camera to not pay a significant price in DR at base ISO to achieve that data-crunching nimbleness.

Yep, but only when used with an electronic shutter. Panasonic only implemented DGO for the EFCS/mechanical shutter on the S1 II, likely for this very reason.

They implement the same DGO for video on the S1 II, which by design is required to use the electronic shutter.

True, but that’s like saying that a 28-70 lens doesn’t perform as well as a 24-70 lens because it can’t go to 24mm. Which is true, but it doesn’t say anything about the image quality of those lenses.

I’d be happy to, but not everyone seems to have the same definition of dynamic range. Bill Ferris mentioned “dynamic range at ISO 400”. So is it the absolute widest range of brightness values you can get out of a sensor, or is it that, relative to ISO?
You introduced the Z8/Z9 into the discussion, then claimed the discussion switched from sensors to cameras.
Could you try to read more understanding, maybe? Sorry but I feel like I have to get every little detail exactly right, or I get this kind of response back. It’s not much fun.

I didn’t make this claim in the first place anyway. My point was that sensor performance, to me, means signal to noise ratio. Not signal to noise at the lowest ISO. If you disagree, fine. If according to you, I don’t use the proper definition of DR, fine. There is still value in that, if you know the Z6III doesn’t go lower than ISO 100, its DR is ok. Not great, but ok. Or at least I think that’s how it could reasonably be described.

This is where I’ll leave it anyway. I’m working as well and I can’t keep so many balls in the air as I seem to have to here.

Dynamic range is the ratio between the largest and smallest measurable values of a specific quantity (source). For images that means the values from saturation to the noise floor, where some define the noise floor as an SNR 1:1, whereas others like Bill Claff define it as 20:1.

Perhaps that's the issue - everyone seems to craft their own definitions.
 
Perhaps daring to lift my head above the parapet again - I hope Tom Hogan does not mind me quoting from his Z6 III review.

The purpose of this post is to perhaps get back to photographic reality :-O

Tom mentions in his tests that he finds no Z6 III DR disadvantage over the Z6 II above 640 ISO, and just over half a stop below 640 ISO.

Quote from Tom "I see a maximum of about 10.5 stops of dynamic range in my tests of the Z6III. I regard that as more than enough for virtually any use " (my bold).

The Kodak 8 Gray Scale and Colour patches from 48 years ago are a bit limited in 2025 for testing dynamic range.

Imatest has a 20 patch system .

The Imatest target is back illuminated, is intended to cover only the central part of the sensor area to limit lens corner vignetting, and otherwise is to be used in a darkened room with no frontal light falling on the target area,

Imatest mention that lens veiling flare limits the dynamic range that can be recorded by the sensor when a lens is attached.

Shooting outdoors, particularly with elements of frontal lighting, the 50mm f1.2 Z with Arneo and Nano coating should have less veiling flare than the 1995 50mm f1.4 AFD.

Dynamic range achievable can be restricted by both the lens used and the scene lighting.

The different methodology (to Imatest) used by Photons to Photos seems to produce an about 1 stop less DR score than Imatest.

I suspect Tom Hogan's Z6 III 10.5 stops DR test finding is based on outdoor photographic situations somewhat different to the Imatest methodology.

Whatever dynamic range number might be applied to the Z6 III at 100 ISO, like Tom Hogan I I find it has more than enough DR for almost any use :-)

In lots of ways good photography is similar to learning to play a piano - it takes practice to develop skill in either activity.

I think we can all agree we've come a long way from the early days of digital. We're splitting hairs here. IMO

Any use, prior to the invention of HDR televisions, monitors, and smartphone screens in the HDR specification released 10 years ago.

"UHD Phase A defines HDR as having a dynamic range of at least 13 stops (213=8192:1) and WCG as a color gamut that is wider than Rec.709"
