The BIGGEST ISO Mistake on the GH5 / Panasonic Cameras

Love the content as always. I personally from my testing would say that I would still try to keep my iso low for bright scenes but I have gone to iso 800, 1600 and been pretty happy with my results but I would not say that it is worth it to shoot at higher isos even in bright scenes. It all depends because I used it as a way to add film grain since I was shooting humans. If you were shooting a commercial for a product like soda or a snack then the clients might want it more clean. I get what you were saying and it is true that people should not be scared but people should be also thinking about why they should raise it. I also keep my noise reduction at -4 to get more noise/pleasing image since I hate how noise reduction smoothes and destroys images. What setting do you keep yours at. Great video once again.

Been using a gh4 forevver finally got a gh5 and was blown away that it has 100 ISO. Had this video not randomly autoplayed i probsbly never would have left 100 assuming thats the way to go. Great info!!!

This really helped. Thanks!

Dude great content ! Keep going 📈

QUESTION RHETT THOMPSON?
On High Quality Bit Rate Long Run VIDEO'S...DO Either GH5 Or Olympus EM-1 MKII Video FILES Get Split Up Into Multi Piece Bits?
IF One Does But The Other Doesn't ..PLEASE Tell Me Which One Does & Which Does NOT? Or IF Both DO?
I'M Of Course Wanting One That Just Spits OUT One Big FILE & Not a TON Of Multiple Small 2GB FILES That Needs Special Software Stitching Together?
THANK YOU🙂

I enjoyed your discussion. I have two GH5’s and GH5 Mk2. I shoot live theatre, concerts and dance shows. I live at ISO 400 and 800. Normally I don’t think about ISO but recently I spent a couple of weeks in the Caribbean and it was extremely bright. I used a variable ND filter but all my video footage was rubbish. I’m old and I couldn’t see what was in focus and what the exposure was really like. I think my ND filter was poor. I also think that not being able to use a matte box or lens hood made a difference.

Is G80/85 any good for recording in somewhat dimmed light? 🤔

Underexposing is almost always the reason when people complain about noise. Panasonic doesn't help that because I think they cheat a little on their ISO ratings. I find that it's best to overexpose by ⅓ stop or, better yet, use the luminance guide and expose to the right without clipping.

Finally someone who knows what they're talking about!

If the storytelling is great they will ignore the high iso noise.

What is the native ISO for Panasonic GH5 II? Is it also 400?

Thank you for the video! What exposure value is considered correct on the exposure meter Panasonic GH5 II and what is the exposure metering mode?

Does the sigma 18 35 become 10 25mm and 50 100 becomes 35.5 71?

How-lee shit, I didn't know 400 ISO would give more DR then 100 ISO , never shooting 100 again! TY!

Considering I have more than enough light available and a variable ND to fine tune the exposure, so that I can choose whatever ISO I want: What ISO is generally best when NOT shooting in Vlog? I heard 400 is best for Vlog, but I´m using CineD. So I guess it´s either 400 or 200, but people say different things.
And by the way, I´m not on a snowy mountain or something like that, just wondering for my general go-to ISO setting.
Thanks a lot in advance!

I totally agree with the dont care part
Some of my first videos i shared with people were really overly exposed and noisy, but those are the actually the ones i have gotten some of the best feedback on.
Personally i can't go over 1000 ISO because i instantly notice it and i feel like my footage is just completely ruined. I'm just really picky with noise and i think most of us are, noise has gotten itself a bad reputation which it doesn't deserve
Great video man

Learned a lot here ~ Great info/video ~ Thanks!

Your video is making me nauseated. Lots of people cannot tolerate moving images which are shaky and not stable--it causes motion sickness and is a well known medical condition. It's a bad idea to have a handheld shaky camera just for the sake of having a shaky image. It is literally impossible for a lot of people to view your video.

You literally just fixed the biggest thing holding me back from getting the shots I want! All I’ve ever heard from day one was drop the ISO. Thank you for opening my eyes to the actual functionality of it and how to use it properly. Super informative. Just ordered a new Voightlander lens too based off what I’ve seen in your other video. Loving the content.

Great video but just wondering why my camera only goes as low as 200 iso both in photo and video mode ?

bravo

Great video. I didn't know that low ISO crushed the image. I always hated the GH4 highlight roll off.

Great video buddy. Makes alot of sense

Great stuff! Thanks!

Gracias 😊

So if I am shooting a night time rocket streak shot, where I will be using the long exposure noise reduction function as I will be exposing for 4 minutes or more, will the extended ISO100 benefit me as I go from a smaller aperture like f16 to a larger one like f10 of f8?

I've done some testing since and you are correct and right about that 100. Thanks for answering my question. NObody is saying this anywhere and I'm a GH5 nut and watched every GH5 video out there. I know there is an a announcement coming today but most people say we won't see GH6 until 2022. What do you think?

Cant seem to put 200 iso at all on my gh5. it says in the "iso sensitivity" - this item cant be chosen

Great information, thanks! WHere did you get that the native ISO was 400? I couldn't find this on Panasonic site?

Very Cool. Are you talking about photo only. Would you apply this philosophy for video. I think not. Let me know what you think please

Maybe i'ts just my taste or style but I love the way the gh5 looks when it's a bit underexposed and you bring it up rather than perfectly exposed. (using v-log)

Such a rad transition.

Subbed. I agree

Great ISO explanation! Seriously this is one of the best ISO videos I've seen.

Hello from Toronto!
I shot my last two short films on my channel with the GH5 and Leica 12-60mm. I had nooo idea about the effects of highlight roll-off when you use a low ISO vs. a high ISO.
You can see in my "Rat Race Blues" film that I could've used that technique for a couple shots. I wish I saw this video earlier!!

In years to come sensors will be so good that there will be no noise and they will be adding filters to add back noise

Have you tried iDynamic for video - setting ISO to auto and use iDynamic (set to auto) in a room with background window daylight shooting inside which provide a much smoother dynamic range between the window daylight and internal

Thank you for the video. I have many different camera brands, but Panasonics such as my G85 colours - specially on faces - is horrible. It creates extra red and yellow colours that's very hard to remove in post process. Wondering if you have or noticed similar issues.

Nice, thank you!

this video is a winner, great job

You made the first mistake 6 seconds into the video. XD
ISO isn’t an acronym.
It comes from the Greek word isos, which essentially means equivalence.
The ISO website itself that coined the word explains it meaning and derivation on their website.

(If it was an acronym it would be “I.O.S.” For the
International Organization for Standardization)

So its pronounced “Eye-So”.
Not “Eye, Ess, Oh”.
:)

Thanks for the tips I still rock a gh4 and it’s a work horse have been thinking of dropping a mortgage payment on the lecia 10-25 f1.7 your thoughts?

You are seriously confused both on how the camera works and what the implications are. On the GH5 ISO is not a complicated topic, the camera is ISO invariant when it comes to shadow recovery. You also make some confusion about definitions. The value of 200 on MFT camera is the base value where gain control is applied. The extended ISO values are those where highlight compression is applied. As your video editor does not expect that and does not know how to deal with it the highlights look clipped but they are not. 400 is simply the value where noise reduction starts working there is no benefit shooting at 400 vs 200 if you are exposing properly. I do not recall reading any documentation nor statement from Panasonic where they mention native ISO for any of their standard front illuminated sensor digital cameras. Some of the examples you use to make the point are also not well chosen like the black frames which only show that read noise on a standard front illuminated sensor increases with gain, this is always the case unless the sensor has a dual gain architecture. For a video that is supposed to help people not to make mistakes this is pretty confusing

Nice video. I have g85 and its noisy and i dont care l. Haha

Is 400 iso on the GH5 the native iso when you shoot non-log profiles or when you shoot VLog?? Or both?

the sensor is amplifying and searching for light in the dark at any ISO thus creating MOS noise.

Nicely explained! Learned something new about the iso, and was curious about what the lowest extended iso vs native iso were in contrat to one another. Thank you so much for explaining
