Fun fact: CineD tested >the Nikon ZR mainly to highlight just how impressive the Lumix S1II still is.

CineD conducted an in-depth test of the new Nikon ZR full-frame cinema camera. During their review, they noted:
These values are all in the middle to lower ground for a compact hybrid consumer camera. Recently, the Panasonic LUMIX S1 II showed what is possible, especially with their “dynamic range boost” feature turned to “ON” – it shows 2.5 stops more dynamic range than the Nikon ZR for ProRes RAW (when comparing dynamic range values between cameras, you should always compare apples to apples, hence RAW codecs vs RAW codecs and internal compressed codecs vs internal compressed codecs).
and further down in the review:
Putting this into context, the Panasonic LUMIX S1 II managed 10 stops of exposure latitude (Lab Test here) with DR Boost “ON” (9 with DR Boost “OFF”), albeit at the expense of a high rolling shutter. I really urge you to have a look at the LUMIX S1 II results again. You can clearly see how much better the LUMIX S1 II behaves in the exposure latitude discipline!
