Lumix S1II Impressive Peak Dynamic Range Performance

[Interceptor121]

Not so at high gain (ISO 800) there is no increase there

Noise reduction at ISO 6400 generally the camera is not as well performing at high ISO like other Lumix Models but very similar to the original S1





The values at extended ISO are in Medium Format range (12.41 EV)

At base ISO 11.75 is a stellar value

Testing the camera for a few days will post some images at some point

As far as I know, S1ii doesn't enable HCG-HDR in photography mode. DPReview says there may be some noise reduction at base ISO. Can you double check that?

This section of dpreview has no mention of dual gain and dual gain has nothing to do with HDR photography

The camera has noise reduction at ISO 6400

At base ISO does not have any special shadow noise issue contrary to what they say

Very good result but I thought extended ISO could decrease dynamic range.
It means we can use extended ISO without any penalty ?
So why Panasonic didn't used ISO 50 like base ISO ?

Extended ISO is not linear in essence the highlights are compressed from bit code 8147 which creates a number of other issues

The data are looking really good and significantly better than the measurements of the Z6III, what should be the same sensor. Is there an explanation why it's so much better?

Also the curve doesn't look like a typical dual native ISO curve.

Yes there seems to be no dual gain that you can see

 

[sfrankel]

Do you have comparison graphs yet for dynamic range and read noise between the S1ii and S1rii that you previously evaluated? What are your thoughts and strengths and weaknesses of the two cameras? Do you see a difference in color science between the JPEG and RAW files or does it just come down to processing preferences? My interest is for photography only, not video. Thanks for all your current and prior efforts in evaluating the cameras.

I provided the dataset to bill claff who will publish imminently

For what concerns color science this is jpeg only and I do not shoot jpegs once you use adobe you rely on adobe mapping of the colors though camera profiles exist they are not identical

Did you perform the test in mechanical or electronic shutter? Did you use single shot or burst? Maybe Panasonic uses DR boost, what you can enable in video, as default in some photo modes? That would explain high DR as well as the missing dual gain.

Mechanical shutter. There is no DR boost for photos

I know there is no DR boost you can switch on and off. But after seeing your measurements, I thought Panasonic reads the sensor in certain situations, when rolling shutter makes no difference, in the same way they do with DR boost on in video. That would explain the much higher DR compared to the Z6III, which is said to use the same sensor, and the missing dual gain in the graph. Maybe you could also perform the test with E-shutter?

No it does not otherwise it would not be able to sustain 60 fps and your shutter speed would not go lower than a certain amount

The Nikon camera always lag on DR on other competitors but thats to do with something else I believe

Well, it can't do 60 fps with mechanical shutter. It only can do it with E-shutter. In mechanical shutter it only can do 10 fps. In mechanical shutter, a slower RS would be less noticeable in general because it's downsides are covered by the mechanical shutter.

I believe S1m2 enables DGO (or DCG-HDR as Sony calls it) in photo. To test it, OP can shoot photos at 14bit 60fps burst mode to see if PDR drops substantially.

Well, it can't do 60 fps with mechanical shutter. It only can do it with E-shutter. In mechanical shutter it only can do 10 fps.

The manual is quite clear when it records 12 or 14 bits which is related to speed priority setting

the raw file tag say 14 bits either way all other cameras drop somehow the bit depth past certain frame rate

For the situations you will use it dynamic range is not key especially as the autofocus cant keep so you will have pretty much a fixed scene

I think he also could just try it in E-shutter and mayd maybe check the readout speed with an LED light test.

There is no DGO in photo

Official results on p2p the extended iso had an offset

There's no DGO option in photo mode. But that doesn't mean it's not using it. GH7 and G9II enable DGO in photo mode by default without any DR Boost option either.

The PDR chart looks quite like how GH7/G9II behaves.

The ISO-Invariance test results of ISO100+6EV and ISO200+5EV are not in the same league compared to basically all other FF cameras. I don't think it's only due to some fancy NR method.

I'm really curious what's really happening. And it's weird why they don't market it.
