Overlooked in the first articles about this camera is the 4K H.265 mode of the Panasonic S1. Similar to the Fuji X-T3, this will allow 10bit internal recording in HEVC with launch firmware version 1.0 – no need to wait for the paid 10bit update.
3840 x 2160 is available in 10bit at 24p, 25p and 30p with no crop – it is full frame.
The later paid update is for a higher bitrate 10bit 4:2:2 mode and V-LOG, but in the meantime 10bit H.265 provides the silky smooth colour of 10bit with HDR and much smaller file sizes.
