Exposure and brightness are the same net of what the camera thinks of it

Exception of the lens you mention a lot of Sony basic primes are not beaten by the best zoom Example 35/1.8 85/1.8 are super sharp even 28/2 does not get beaten pancake depends I have the G series ...

Unless the prime is really bad... The point is what matters most to you If this is ultimate optical quality take primes, however if you don't know what to expect or can't change lenses on the field ...

This is not what this test is about. This test is about producing an image that looks the same this is achieved by putting the lens aperture two stops away. After that is done you take shots in ISO ...

have a look at the base ISO case I am not trying to demonstrate anything I am curious what people see into things it makes you reflect about what is a fact and an assumption

Those tests assume same f/stop and shutter (maybe) and don;t produce the same visual image. So they are irrelevant

Nope that part is only to calibrate the system on what min max look like it has absolutely zero to do where the DR is compared to middle grey And the camera does not give an absolute crap about ...

It is not the SNR charts correspond to 1:1 pixel so for both cameras 30 dB are at ISO 800 Full SNR measurement does not look at saturation value but at grey scale at nomimal ISO. Once we have ...

DxOMark provides two measurements DR this is done with a lens lokking at bright and light patches using ND filters and aiming for SNR=0 dB photonstophotos does not look at that however it derives ...

It does not matter. As long as when you import the image in your editor middle grey stays as such which is grey patch on bit 116 code in 8 bits Do you know if in the camera you have middle grey is ...

Are you asking me or DxOMark and photonstophotos? Pear DR is when SNR=1or 0 dB as per DxOMark text I pasted here This is because in photographic sense they are related Feel free to complain to ...

For example?

Thanks for putting the effort in manufacturing those graphs which have no real foundation but look good for what you want to put across DxOMark has no idea where middle grey will be because ...

Read the imatest documentation ISO can be measured with Saturation or with SOS. The issue is that if you use it for saturation you cannot guarantee the sensor has a linear response. So what camera ...

Yes I was just pointing a fact There is a reason why that is not the case. My understanding is that sensors don't behave linearly across the range but there are shoulders. In addition there is some ...

Sony creators app does not support the A1

I have this lens and I am aware of the reputation issue however I do not see how this lens is going to be beaten by a zoom even a great one I have the 24-70GMII and I have not done rigourous ...

DxOMark does not give you the number of stops below middle grey until you have your SNR limit. DxOmark does not perform any latitude tests. DxOmark does not even consider middle grey for their DR ...

I have eyes my full frame images look better actually but you need to understand what better means. While what you say is true at pixel level you need to understand that photonstophotos or DxOMark ...

This is one use case and it is a practical one i have another for base iso when i print on a given size the image stretches the idea of setting the output with lightroom is meant to illustrate that ...
