  • @drdave Indeed noise removal does not add detail.

    I wonder if Gh5s could make better implementation of this issue. Maybe giving more structural noise, controlled and refined could make Grain like noise and gain detail loosing dynamic range.

  • @Bwhits

    NR is so deeply implemented on Gh5s video that as. Someone noticed, its too Deep to really know what it true or not.

    That is why a hack on this camera could make a real diference game changer. I wonder only playing with matrixes and codecs could make Gh5s a troyano horse

  • Remember this.

    M4/3 sensor size it's like your Retina size. It is special way of gathering images. More like human vision.

    I know maybe this has nothing to do with real life but from my experience focusing and achieving the look, and operation of lenses are far more natural. I can't say how or why I feel this. I have used all sensor sizes and all cameras except panavision and I swear it's not the same handling a gh series with evf and follow focus than an otherncamera

  • @bwhits

    Yes my friend. Panalenses distort the natural characteristic of things, since they are electronically corrected on camera, all its bad habits. Chromatic aberration, distortion and else. I don't know too what extent in the video mode this is implemented, but on photo its surely running.

    Panasonic lenses are extremely high detailed lenses that make footage with clinical characteristics. This for me renders the worst and most plastic images on the market. Grate for showing camera capabilities, not for story telling.

    I never use Panalenses on my rig. Not a way to get constant results on follow focus, behaviour and character.

    About Sony hlg I haven't tried it. Neither resolve on it. I can say premiere and Sony log are not friends.

    Gh5 has all fs5 features except 240fps 10bit 422 and 4k 60p 10 bit. LSI does support it, since Eva 1 has it, but panafriends won't implement it here. Shame on them, but fragmented segments here are very important for sales, and don't cannibalise on own products.

    Either way, Sony is very robust but fs5 plus external recorder and expanded backplate for extra features is kind of too expensive... Buy fs7 instead.

  • @bernie

    The issue here is the right iso setting for optimal performance.

    I think the announced based iso is not what they say. It is not dual native iso. It is an implementation which was adapted to run "like" dual native iso, but it is not. It is the Hdr feature on sensor, that is emulating another phisical readout, you could understand by seeing the sensor technical papers.

    What I meant is that this sensor has an ideal dynamic range on an ideal iso. We don't have that real information. From what I've seen iso 800/ 2500 seem the right one, but I can't say due to improper testing. And marketing lies.

    All images shown on videos tell the same story. Overwhelming low light for m4/3, but detail and dynamic range being affected by noise reduction implementation, and sensor properties.

    So... This camera ha an ideal range... I can't find it since the "dual native iso emulator" give us two values that are not native in nature of the sensor. This, I belive in variacam series, in this case, it is not.

    So just for being tansparent, from my stand point, this dual native iso is pure marketing. This is bad for pros who understand sensor behaviour in a very technical way. Makes me doubt about real limits.

    From what I've seen iso 6400 is the limit of clean.

  • You can always remove noise; you can't add detail.

  • @endotoxic @Bernie I don't know if it's been mentioned here before... but to my eyes... both the GH5 and GH5s look better without Panasonic lenses. The footage with native lenses just seems crunchier and more compressed, no idea why. I thought it might just be user related... in that people without native lenses might be into dialing the images in more (turning everything off)... but I see it in EVERY video with Panny lenses. Maybe they're extra high-contrast or something? Or... do native lenses trigger extra NR somehow? I dunno...

  • @endotoxic The fs5 has an option to shoot 120 FullHD continuous 422 10bit internally, in addition to buffer 240p FullHD 422 10bit. No camera beats that.

    With an Atomos Inferno you can record 240p FullHD continuous 10bit 422, plus 4K DCI 60p 10bit 422.

    And the auto ND is magic. In Resolve I have no trouble getting good colors from log. HLG is even easier. And I prefer the colors to those from Pansonic Vlog.

  • Thats the trade off, obviously detail loss is much less obvious and acceptable for viewer in video vs more noisy image.

    Obviously it is that software engineers had been forced to do to show "big advantages of large pixels". :-) And solution was same.

    Actually it also explain why you never have any honest option to turn it off.

  • @endotoxic @Bernie How far can NR be turned off?

  • @endotoxic

    Lack of detail is due to noise reduction. By looks of it, noise reduction has temporal aspect to it that allows for less noise vs previous in camera NR , but as the expense of details. Its the same technique that A7s series use.

    If you look at RAW noise on stills output at same ISO , you can see completely different characteristics. Its the same with A7 series.

    Higher up ISO it becomes mushy as detail and noise both get compressed. Thats the trade off, obviously detail loss is much less obvious and acceptable for viewer in video vs more noisy image.

  • Gh5 s lacks detail in all tests I've seen. It was expected since it has less native resolution and downscaling to 4k from sensor in gh5 gives better detail

    It would be interesting to see more resolution charts and how much the s line lacks behind.

    The yellow tint is also very much present on Gh5s. Though it would not be a problem to implement both footages and intercut them.

    I'm really close to buy new gear this time around. Eva-1 it is extremely detailed 4k, it is OK, but C200 kicks it ass un low light and color implementation, but it has this shit type code option and raw is not the answer for every take you do. Sony fs5 fs7 it is a pain in the ass to make color correction for any Sony log profile and lacks constant slow motion, Ursa mini Pro is still in year 2010 in its iso range and sensor implementation.

    Every time I see this Gh5s footage and compare it to other bigger cameras and heavier equipment, make me wonder why I started with m4/3 in the beginning. Light weight with robust implementation of codes, versatility, only bad low light. Now the bad lowlight is gone. 10 bit 422 clean image and v-log on it.

    The last B&h broadcast about gh5s showed me what could be donde and how much light it get gathered by this sensor. It is a clear indicator of the power of the sensor

  • Gotta love PB epic rant against lack of stabilizers
    Which is right after his rant against the lack of it in the GH5s

  • @Ironfilm it's easy for us, but having done a bunch of short courses I can tell you a lot of people don't know what it is. The software sure has gotten simpler; I vaguely remember not being able to play Prores files in Premiere, but I started on version 1.5. 1,5 appeared after 6.5 or something really weird, Long time ago. Must have been CS3 which came after version 2 which was really 8.
    Another issue for the stuff I do, which is events, is that ppl have an issue with raw or prores if filming a long event. It's tough to handle that much data in a multicam array if you don't have experience with really large amounts of data.
    Re EVA1 I'd consider renting it, would be interesting to test it against the Sony 6500 and the GH5. 6500 pulls a lot of detail, I'm always amazed by that. GH5 has some great options. 14 stops DR would be great if true....and if the stops are in the usable range which is another issue with DR.

  • I'm not sure who's buying this gear, but I would guess that a fair portion of the market is for serious amateurs, even for EVA1, etc., and a lot of ppl starting out can't always afford the high end gear. I mean, whose buying this stuff? Interesting question.

    I know someone who'd just finished first year of film studies at uni and purchased an EVA1! :-o

    and a consumer friendly codec or two.

    ProRes LT isn't friendly enough?

  • @Ironfilm I watched the whole Caleb video and there's no GH5s in the video, I mean, he reviewed the camera without the actual camera.

  • Well, personally I don't really care about debating IBIS, but, ideally, being able to switch it on and off so its "really" off is what I would consider not only practical but desirable. Then switch it on if you need it. There's a lot of super high end gear that has a gyro in it that runs even if you turn it off, and I've seen this gear on some really high end sets. I don't think ppl think twice about it in many situations. Turning it off is just engineering. Simpler than designing the IBIS, for sure, to make a switchable version. Remember lock down mirrors? Those were the days when that was what ppl worried about. Want five axis stabization with a lockdown mode, well, hey, Arri makes one, so why not Panasonic. And Arri makes great stuff. Andthey aren't making those systems just so no one will use them.

    @Ironfilm re: the sales--I'm not sure who's buying this gear, but I would guess that a fair portion of the market is for serious amateurs, even for EVA1, etc., and a lot of ppl starting out can't always afford the high end gear. I mean, whose buying this stuff? Interesting question.
    Look at Blackmagic, it isn't expensive, it's very pro oriented, great quality, but they really don't target the mass market. They could be way higher in sales with just a few bells and gizmos, and a consumer friendly codec or two. Photo stacking, whatever.... Anyway, I'm happy if I can buy a six pack of cameras for cheap. Half of those have IBIS, half don't--the "near" cams are completely silent for close work, and the "far" cams are completely steady with a telephoto. A lot of my camcorders over the years had IBIS plus in the lens running all the time, and this was sold as a "pro" feature. A lot of those camcorders are used once a year for parties, but some of them made some great indie films.

    Not sure I will see a difference with the "s" model, but I will of course rent it and test it for myself. After all, you can find any opinion on the web if you keep looking--it's fuzzy, it's sharp, etc. So I'll try it out.

    Plus, who knows with the updates? I thought the G85 was crap when it came out, but when they fixed the IBIS it tuned into a really amazing camera with just a firmware update.

    PS, I have to say I loved my 12mm on the GH2, so the wide sensor does get brownie points. Don't know why they went away from it, just get an Xacto knife and chop down the APSC from the Sony 6500.

  • They shouldn't release any camera with IBIS.

  • They shouldn't have released this at all without IBIS.

  • @Scot "As to the no room for IBIS that also sounds like an excuse. It's the classic marketing joke we designed it that way it's not a short coming it's a feature."

    No, the sensor is bigger. The extra size would require a redesign (potentially allot more expensive). They made a trade-off for a larger, smaller-pixel, more light efficient sensor. It's not a marketing joke. Do you really think they could just drop a significantly larger sensor into an IBIS designed for a smaller size? That's just not very plausible.

    @IronFilm posted a great video about it above. Worth a watch for the visual examples!
