I have tested the new firmware of the Z7 using my own usual workbench, excited kids running around indoors in crapy led lighting lacking power.
And I am happy to report that the Z7 with 85mm f1.8 S is now very good. Firmware 3.0 was already a very significant improvement, but as far as eye AF in AF-C mode goes 3.1 is even better.
It’s still not quite as good as the a9II but it’s IMHO at the same level as the a7rIV.
Cheers,
Bernard
