Nick Driftwood posted that “Panasonic GH4 V log L versus Sony A7s S Log 2” comparison video. He writes:
Here’s test number 1 of a few coming up. A rather quick ‘vanilla’ test done in the back garden of my 83 year-old father – both cameras using similarly matched lenses , shutter and aperture was adjusted to keep in accordance to the default recommended LOG ISO as given by each camera. Exposure was bang on 0 for each. Nothing else I will give away about the above…just yet!
Panasonic GH4 has ISO 400 in V Log L and Sony A7s has 3200 ISO.
A7s is a full frame, GH4 is a M43.
I may or may not have moved the position of the focal length of each lens.
GH4 lens was a 12-35 Panasonic lens and the A7s was a 24-70 Canon.
This is a fun test and not to be taken seriously by camera fanboys.
With a little adjustment (not shown) its fairly easy to make both cameras match each other during grading. 🙂
3D LUTs employed: Panasonic VLog_to_V709_for_V35_ver100 & Sony FS55 1.From_SLog2-SGumut_To_LC-709 .cubes placed using LUT Utility plugin on FCPX.
NO OTHER GRADING DONE ON THIS
All 4K recordings were performed originally on an Atomos Shogun (zero’d) in 422 8-bit on the Sony A7S and 422 10-bit on the Panasonic GH4.

L-> 7s R-> Gh4
Also my guess. The greens on the right are “funky” at the 100% applied LUT ^^.
(That – And because of the shallower DOF the left one is for sure the A7s.)
Same guess here,but that 3 stop difference in ISO mean that DOF may not tell nothing.
That´s true – Forgot about the ISO3200 vs ISO400 difference. ^^
Noise in the blacks/shadows might be the tell, 10 bit noise should be significantly less then the 8 bit counterpart.
I think on the left is Gh4 and on the right A7s.
I agree, because the right video seems to have clearly more dynamic range, so that’s got to be the Sony.
Probably yes and also because Gh4 had ISO 400, the A7s ISO 3200 and the apertures opened accordingly.
The good thing is that the people are guessing! The ungraded versions are indistinguishabilly flat. No problems to mach different footages from both cameras in production as for me.
L is A7S.
why Nick don’t tell,which is what?
but i read on normal left to right he write GH4 on left and A7S on right.
A7s on the left, seems like typical Sony over-saturation. Panny colors look more neutral, GH image also seems to have slightly better DR in log.
Log, regardless of what camera, is crap if it’s not 10bit. GH4 VLog with Shogun is the way to go.
It s like saying that all C100, C300 user are amateur .
No it isn’t. I’m not questioning the cinematography skills of anyone that owns an 8bit Log camera. I’m questioning the manufacturers. I’m a colorist by trade. Trust me, Log in 8bit, though somewhat useful in some cases, falls apart very quickly when pushed. I color a lot of GH4 footage, and grading 10bit GH4 footage as opposed to 8bit is so much better that it’s ridiculous.
Yes and Raw is better than everything else , but here we are talking about a 1500 usd camera that can record log in anamorphic in 4k , I m a colorist too and I d rather have log on 8 bits than no log at all , especially if it smooth the roll off . Of course I would like 10 bits/prores/raw ect but for the price I m still amazed by what is camera can do . Regards.
Left is GH4, slightly sharper. If using m43 lens, sharpness and DOF can be achieved. 3200 ISO for the a7s vs 400 for the GH4. The lens was stopped down to f8-f11 on the A7S and likely at f1.4-2 on the GH4. Would love to see the final results. Do I get a candy if I’m right?
Yea I’ve changed my mind and agree with you. At 1080 I thought it was the other way around but at 4k it’s a huge difference in sharpness.
Yeah… f/1.4-2 with the famous Panasonic 12-35mm f/1-2…..
I’m afraid you won’t get any candy….
However looks like you are right about which is which: GH4 left, A7S right.
I would say GH4 at f/2.8 and A7S at f/8.
i’d say your on point here also.. the lens looks like a wider pov on the left and not flattering to face shape at all. i’m guessing SONY RIGHT as no ND was used which means Nick had to hit F8 or higher to get the same look but with a deeper DOF as a result which is why everyone on here is guessing wrong lols. my money is on FF look on the right – and sony colours on the skins/green i don’t mind the flatter greens but i’d cut the magenta a bit on the face in grading.
BOTH look good.
if dof is any indication im guessing the left is the A7.. much shallower. also there seems to be a crop factor since the right side seems “closer”
He says that he may have changed focal lengths on the lenses; I assume that the camera-subject distance was deliberately shorter on the left shot to make people assume it was the a7s.
I was thinking that too…also the left after grading show much more color data, as a 10 bits prores file.
GH4 … good for youtube videomaker but not much more.
is there anyone taking still pictures with a GH4?
So it’s good to the 99,9% of us.
Will you kindly let us know when will be your feature film in theatres ? 🙂
The GH4’s stills are fantastic, you should try one sometime.
I’m a photographer by trade and use the GH4 for stills, mostly because I also shoot video. I have other backup m43 cameras also.
You made me laugh. Gh4 is widely used for small or large budget films, weddings, and even in television industry. When we ordered ours, there was TV studio which bought 18 bodies.
Gh4 is still a very powerful and popular 4K video tool which happens o also take good pictures.
Left is just horrible a closer wider angle of view… not flattering.
Makes sense that Driftwood would dick around people with the V-log, just like Panasonic has been
I honestly couldn’t tell which was what but the different effective focal lengths produce different results as does the camera angle and lighting up the garden or into the darker hedgerow. Big difference in ISO used? Both are usable, it depends on requirement.
Because there is so much disagreement over what is what, I’d say you’d do just fine with the GH4. Though both are important, image quality takes a back seat to the quality of the storytelling.
BTW, I love the William S. Burroughs look of the Subject.
I really can’t tell which is which here. I haven’t used V-Log yet, Come on Panasonic!) so I don’t think I’ll take a guess. DR, resolution, color is close on both and could probably be graded to look the same.
I’ll flip a coin tails the right frame is A7s Heads GH4-
Heads!
I’d guess the left is A7S and the right is GH4, I use the GH4 as a photographer/videographer but I thought a) the shallower depth of field and b) it seemed to have an edge DR wise on the left, which i’m guessing comes from the full frame of the A7S. Still, I use the GH4 and love it.
WHICH IS WHICH: V-LOG-L / S-LOG-2?
Answer: Left is A7s SLog2 & Right is GH4 V-Log-L.
Nice test! Thanks so much! Making me feel a lot better about my upcoming Sony A7RII purchase. Decided against the Ursa Mini as its not as Mini as I would like it to be plus low light is more and more in demand and the Ursa Mini not as stealth as a mirrorless camera, which I enjoyed when I had my GH4.
mate, its beta. japan is refining things. im streamparsing stuff
If you are not toying and showing off with your special treatment, then will you or Panasonic care share the build? Thought not…
The exact reason I left Panasonic. They are moving way too slow with plenty of worthless excuses. Google for yourself, and you’ll see how Panasonic dropped the ball with V-LoG L, how it’s too late, and how they have lost so many GH4 users to their competition. Big business at it’s best
Much respect for your work Driftwood. You’d have to admit that there were some serious marketing, R&D, testing, and promotion missteps for V-LOG L. BTW, No matter what I tried, I almost always preferred my GH2 with Moon T7 over GH4 settings. The GH2 is so much cleaner, a lot less noise and super sharp, especially with Moon T5. Unsure what Panasonic has been thinking. They’ll have to pump steroids into the GH5 just to make a come back unless they plan on keeping up the Canon-like behavior where they accidentally changed the industry and then lost their footing to their faster moving competitors due to corporate Hoo Haw!
