I sold my A7RII and i'm seaching my futur PP for my new A7RIII for shooting still RAW and for vidéo.
As we know PP interact with still raw, i'm searching best profil for maximise DR.
A7R3 have now Slog3+HLG + assisted gamma to see like rec709 but A7RIII is only 8bits, i'm not convinced at all (8 bits banding).
For vidéo my préférence is cine4 + cinema curve + détails -5.
I often matched my A7RII cine4 with 35% of kojicolor2383 rec709 lut with Fs7 Slog3 cineEi@800iso with 95% of kojicolor2383 slog3 lut and for both cameras add adobe kodac 2383 (20%) for skintone.
Now it's time to re-think my pipeline to better match A7RIII and FS7 in Slog3 + S-gamut3.ciné CineEi @800iso mode.

All expériences is welcome!
 
I tried PP10 (HLG + BT2020) for 4K vidéo, it seem's interesting to expériment, it looks like cleaner (banding) than slog3 S-gamut.cine3 in same condition.
I need to test more this PP, his minimum iso is 125 compared to cine4 where minimum iso is 200 or Slog3 minimum iso is 800 .
I graded it with colimetri hdr and add litle touch of others lumetri rec 709 luts, it's a bit new to me but résult was not bad at all. To be continued....
 
I haven't tried the a7R III, but on previous Sony cameras shooting stills in slog mode was a bad idea: you are underexposing A LOT. I don't know which of the others I would choose, though. Probably cine4. But perhaps the III has something better.

I have in my mind ETTR (expose to the right) when shooting with flat raw PP, perhaps it is not good idea but with PP 10 in A7RIII (hlg) iso can be set @125 not like Slog3 iso 800. Anyway DR between HLG and Cine4 seems be the same: 11.
The best way is to compare to see if it brings us Something better in shadows.
 
It is so easy and nice to match FS7 and A7RIII in Slog3 s.gamut3.cine that i'm looking a way to setup A7RIII in cine4 (no banding) with Sgamut.3cine then use lutcalc to made lut conversion (cine4toSlog3) and apply same slog3 luts on Fs7 and A7RIII in lumetri . Any expériences are welcome.
 
I hope sony will update A7RIII in futur firmware (4k 25p @ 200Mbs/s) or 4k 50P, or 10 bits.
The way i can match color between FS7 and A7RIII with slog3 S-gamutciné-3 tells me i need more bandwidth data for A7RIII.
Does someone can confirme me than A7RIII seems better in term of colors banding with slog3 (eposed in ettr) internal recording than older A7 ?
