Dynamic range measured by Photons To Photos: Sony A9III is surprisingly good!

Bill Claff from PhotonsToPhotos measured the Sony A9III dynamic range and there are quite some surprising aspects:

• Except of the Base ISO 100 and the ISO 8000 the A9III is more or less on par with the previous A9II in terms of dynamic range performance
• It also beats the Nikon Z8 at any ISO except again base ISO and ISO 800.
• The Sony A7rV is the Dynamic Range king but from ISO 800 the A7rV and the A9III performs the same!

Bill writes:

• Base ISO is 250 due to low full well capacity (FWC).
• High conversion gain (HCG) is available from ISO800.
• Maximum PDR is quite good considering the base ISO settings.
• Low-light ISO is also quite impressive.
• Noise reduction (NR) is baked into RAW at all ISO settings, and is most noticeable from ISO 16000.
• In the Fixed Pattern Noise (FPN) test, the I LCE-9M3 showed good results. Low values ​​are better than high values.

In summary:
The A9III performs much better than the “Internet” lead us to believe. In fact if you shoot at any ISO expect ISO 100 and maybe ISO 800 you can expect top class results with all the extra benefits that rolling shutter gives you (fast readout, no banding, no rolling shutter artifacts, flash sync at any speed).
