Sony A7III vs Panasonic GH5S - Skintones, AF, Lowlight, Picture Profile

The only 5 things that truly mattered for me between the two for video. Lenses. How hard you need to grade. IBIS. Slow Motion, Gain I've been cutting Media Composer and grading in Davinci for 12 years so I can talk from experience after working with both of these cameras. Color science is too close to matter. Dynamic range is too close to matter. TC jam is bullshit. DOF is a wash if you know how to lens properly. GH5 is 10 bit 422. This is marginally better than A7iii footage. Not noticeable difference however until you do heavier grading or use custom profiles. You will be able to saturate to higher levels on your vectorscope without candyland mush. You will be able to color select more accurately with less chatter. V-Log profile is (generally) less noisy than s-log A7iii. A7III is full frame so you will ONLY be able to use a lens setup that covers full frame. Great for shallow DOF. Shitty for everything else. (weight, size,price,available options) GH5s is larger than any other m43 so your asp-c lenses such as sigma 12-35mm + speedbooster will show vignetting on the edges compared to the old GH5. If you know what you are doing you can get a lot of great glass. IBIS is not available on the GH5s so expect your handheld footage to look handheld (like all full size cinema cameras). Slow motion is much better on the GH5s is every aspect. Higher bitrate and higher framerates. Nuff said. A7III is full frame therefore better at crazy high gain than the GH5s. That being said, the GH5s is useable up to 5000 , which allows slow motion settings with no change in T-stop needed at 180 deg. It is also plenty for everything up to special use case gain boost. Twice as good as Arri Amira/Alexa as a pro comparison. GH5s is newer and has more available on board to create video. A7III is a great entry level full frame stills camera that happens to take bangin' video. They both work. I would choose A7iii if you already have full frame glass, shoot special use footage at high gain, can't shoot useable stuff handheld, primarily take stills. GH5s for people who want a full featured video camera.

This is such an important video. Thank you for taking the time to make it.

Finally, someone reviews these two game-changers. Thanks for the in-depth analysis as I'm trying to choose between the two as a b-cam for my GH5.

Very nice comparison, I'm going to have to go with the GH5s. It's menu system,10 bit, lenses 4k60 articulating touch screen and other options are more of what I depend on currently.

Forget the comparison. This video with a beautiful and very photogenic model, and beautiful music is a piece of art which I will view many times. Thank you.

Hands Down! This is the best way of comparison cameras, no other video has shown it in this way!

the gh5s image quality it's so damn good, I just finish a review on that camera and I'm so impressed with the performance

Fantastic comparison! Thanks so much for this. I've been using Panasonic since the GH2 and came really close to making the switch by staring at the specs of the A7III, but I pulled the trigger on a GH5S last night and am glad I did. While I do shoot stills, it's more for fun and not professional work. Seeing how much more details skin tones were in certain shots, I'm guessing because of it being 10 bit, really made a difference. Thanks for using the 179 AF trick too! I was planning on using that and it's nice to see both cameras are comparable in that department.

THANK YOU, THE ONE COMPARISON IVE BEEN LOOKING FOR.

Rarely rarely you find professional videos like this one. This is high-class bro, and whoever took this is a serious, serious cinematographer. How amazing, this was posted 2 days before my birthday.

I can watch those eyes all day long, regardless of the camera being used. Great work!

Thanks for doing this. GH5S skin tones look really good.

I wanted both cameras but only had the budget for one of them. I ended up ordering the GH5s first because of its more professional video features. I use the 179 degree autofocus and it works reliable enough on my glidecam. I still do plan on getting an a7iii to go with it. Each camera has its place. I'm not sure why there hasn't been a direct comparison video on these two yet. Thanks for the video.

Awesome review! But there is a need to step through the PP's of GH5S too. But anyway, thanks a ton for Your videos! Waiting for the A7S III, but it is easy to predict that new model will cost too much. At this time, GH5S is awesome!

gh5s skin tone is a killer... hats off to Panasonic.. but my heart still goes to Sony... nice review..!!! subscribed!

This was a pleasure to watch. Thanks!

Brilliant colours on both cameras. I’m very much interested in knowing your quick CC process on Sony slog2.

I wanted this video so freaking much. Thanks for doing this to us :) Did you had more time grading the Sony over the Pana? How was the 10bit gh5 efficiency? Something really special?

Great tests buddy. Sony's color is pretty good, the video quality is really good as well. The Gh5s has nicer roll off on skin and gives a more organic feel IMO.

If you actually want to compare a micro 4/3 with a FF then please keep shutter and iso as same & multiply that aperture with crop factor... If you are keeping f/4 in the pana, then you must keep f/8 in the sony. That will make a lot of difference in the whole test output.
