The list of cameras approved for 4K Netflix productions has just grown by two current representatives: The Canon EOS C500 MKII and the Sony FX9 are now both 4K Netflix "Approved". The Canon EOS C500 MKII accepts both full frame and S35 sensor readouts in both Cinema RAW Light and XF-AVC.
On the Sony FX9, Netflix specifies Cine EI (and thus S-Log 3) as the preferred operating mode in UHD with XAVC-I.
For further information about the Canon EOS C500 MKII you can find here our practical test of the C500 MKII and here our lab test.
For the Sony FX9 you can go to here to our practical test part 1, and part 2 as well as here to the lab test.
