Yes, the GH5 itself has the worst rolloff of the bunch. The S has good clipping correction, and I intend to bring the accelerated Alexa style rolloff to the S in the future (need to get a hold of one for measurement)

Looks good! Can't wait to try it out. 

Check it out:
New LogC Tungsten

New GHa Tungsten

VLog + Varicam 35 Lut

I will definitely try this in the future. Great work!

Just want to say the LUTs are great. It's interesting how different GHa is from the GHaLogC-ARRIAlexaLogCRec709 pairing.
Thoughts on a more neutral LUT with basically just the highlight rolloff (no longer having oversaturated and color shifted highlight transition is wonderful), or should I just use the Leeming LUT?
One note for anyone else using Resolve on a non-cinema wide-gamut hardware-LUT display (not specific to this conversion at all, just in general for color grading): Accurate color absolutely requires the usage of a flat system ICC profile, a monitor-loaded LUT, and a 3D LUT in Resolve (3D Color Viewer LUT) as Resolve does not appear to be ICC aware in any way, shape, or form. This isn't particularly noticeable with SOOC footage, but Log footage run through a LUT (let alone complete color grading) is pretty painful otherwise.

I don't really think the ISO interpretation has to be a negative thing... On the contrary, it seems you get more latitude to play with and adjusting the F-LOG or Eterna image in post to bring out the shadows by 2/3rds of a stop is trivial, with hardly any loss of image quality.

Thank you for the answer, Sage!

Quick try in daylight with GHa Daylight on GH5 with Anamorphic 2x . very nice and filmic.
 
 

And... the one that I'm floored by...

Hi Sage,
Will you be offering the GH5s conversion as a free update? I have the GH5 but may sell it to get the GH5s as it would suit my needs more. But I want to get into shooting something as it looks great and also test it out.
Will the color coded engine be an app that you input the Kelvin into to get the lut? 
Sounds intriguing!

@ Sage.  I have remote phosphor based lights by BB&S and Cineo. They both license the same patented phosphor formulation, so quality of the light is the same at the same panel color temperature. I have 5600k, 4300k and 3200k panels.
I am planning using them together to give me a color temperature between 4300k-4400k: 4300k (single 4300k panel),  4400k (combination of 5600k and 3200k) and 4350k (combination of 4300k/5600k/3200k).  I should have said I have tri-color lights, but that would have taken some explaining... ;  )
I would be happy to shoot some test charts. I have a ColorChecker Passport and I can purchase the additional color charts as you require.
Thanks!
Mark

Results look great!

That's VLog at top - and LogC at bottom

Its looking great Jeremy!
Watch this space

The hard part is done; its comfortably a slam dunk, so to speak.
Here's a taste - this is HLG (converted to VLog) and VLog (HLG is on bottom, with equally increased saturation to demo color, and overlayed vectorscopes):

The waveforms are likewise identical, and the conversion is silk, throughout the entire color space.

Its the conversion process itself that is entirely new; its pretty impressive

Vlog is the core of the original GHa; though wait a bit to decide. Something very relevant is coming

Pretty crazy. When I was young we busted our ass to try and get rid of Grain, and now every wants to add it!

Some recent tests with my new anamorphic adapter and Vlog. Really loving the color separation the lut gives. A few frames arent in focus...still practicing this anamorphic thing

Hello Sage! I'm very interested in your idea!
Yesterday arrived my new gh5 and I discovered all the dynamic range of HLG! WOW! Highlights are there!
But I'm stuck with editing workflow since premiere pro doesn't support rec2020... I found this topic so the idea is to use your hlg-to-vlog lut in premiere/lumetri color/Basic Correction/Input lut and in premiere/lumetri color/Creative/Look aplying vlog-to-REC709 lut. Am I right by doing this?
Thank you for sharing your work!
 

That video is sort of proof that 4k has Really narrowed the gap between cheap stuff, and Oh My God expensive stuff output wise. Sure the iPhone X doesn't have 16 stops of DR, but I certainly didn't see where it was lacking in that video, and you have to put yourself in the vast majority of peoples shoes, they have no clue what the hell DR even is LoL
I have the X and it has just about every trick in the book, especially if you use the Filmic Pro App. It has more video stuff than my Note 8. Better specs, but I still sort of like the Note 8 output. It maybe the screen, and the screen size that has more to do with it on the 8 than being "Better". Either way both of my phones are capable of some unheard of output even 3 years ago.
I would be damn proud of that video, to most people that is a winner. And what it was taken with just Wow when you think of it. And in your pocket all the time, just a miracle.

I just saw this video; this thing is really impressing me right now. It apparently has a telephoto lens option. This might just be worth doing something for
