I stumbled across this just now, seems to me a valuable resource to share. This is the chart of my current cameras compared with a Nikon D850  Click here to comment on this image. Link to site: https://www.photonstophotos.net/Charts/PDR.htm#Nikon%20D850,Nikon%20Df

Interesting - I compared my 610 with your 850   Click here to comment on this image.

If I am reading that graph correctly there's no improvement in dynamic range at any given ISO between the 850 and 800? So would I be right that the mystery green camera on this graph is the 'best' of this 3?  Click here to comment on this image.

Can I remind people that these are lab tests done in a controlled environment so as such are not 'real world results'. They are probably indicators of what might be obtained on a good day with a following wind by the average user.

As I understand it these are technical attributes of the sensors and hence independent of "real world" effects.

I dont know but I would expect that the dynamic range at top/bottom end will be more effected. I am no lens technician but atmospherics are a great leveller!

I am a novice in this field but are you two talking about dynamic range in the same way that the comparison is being made in? The dynamic range of an image is, I think, different from the dynamic range of the sensor and while the former will be influenced by the lens etc, the latter won't - see the article here - https://www.cambridgeincolour.com/tutorials/dynamic-range.htm. Or am I up the wrong tree???

Potential dynamic range of the sensor which ultimately gives you an image of good dynamic range. I personally have always been hugely sceptical of DxO results as they are lab based results. Having worked for many many years in a lab I know the difference between ..... it works, and it worked in the lab but I cant understand why it isnt the same here!
