    I'm wondering if it does 60fps in Cinema 4k (4096x2160).

  • EspenBEspenB

    Any more rumors on the possible multi aspect ratio sensor Vitaliy?

    GH5: Full size HDMI and IBIS.

    One of Photokina backstage rumors/leaks is that main LSIs in Panasonic GH5 and new Olympus are very very close :-).

    • Both include dual cards support, but with only one being UHS-II.
    • Both support 422 10-bit video, but Olympus got LSI with agreement to restrict it to HDMI output.
    • Both cameras will have impressive burst performance.
    • LSI supports new sensor based 5-axis stabilization algorithms (it means that it has necessary outputs to all coils and things). Will be strange to not see it in flagman. Stabilization algorithms sharing was one of points in new agreement rounds (long time ago).
    • GH5 sensor will be custom.
    • Some quiet talks are also about special film like filters ala Fujifilm.

    P.S. One of the talks is that new G80/85 shares almost same LSI with GH5 but restricted.

    I was expecting 422 @ 10 bit from Panny, after all they are working with Leica and they sell it by now in their cameras for the rich amateur. It might even be that they have an agreement about when Panny may offer it in a camera for the mass market (Sony had a similar grace period with Panavision regarding the F35 in it's time).

    Once the GH5 is out, this will break the dam. Technically it's long overdue, but as long as others could sell 402 @ 8 bit (like Sony), there was no competition in the price sector.

    @Tron

    Please don't go into this. Make separate topic if you like.

    @Walkaboutcamera Panasonic chose to compress the GH4's V-Log L range in favor of mirroring the Varicam's luminance curve. The Varicam is capable of 14+ stops, the GH4 is only capable of 12, so there is clipping (mostly in highlights). In theory this approach is better for professional color grading between the two cameras when applying LUTs. If the GH5 has an additional stop or two of DR we may end up with a V-Log "L2" profile that is much closer to the Varicam Log curve and more effectively "fills" the extra luminance range that 10 bit affords. It will depend on the sensitivity of the sensor that they shove into that little beast.

    @Walkaboutcamera

    I removed few posts due to them being offtopic here, make new topic and use all your flame talents.

  • DrDaveDrDave

    You see, @Walkaboutcamera the majority of ppl on this site are interested in things that actually work. If you have some useful information to share, we welcome it! Put some examples online and we can take a look at it.
    When you post "Tron failed the test" or "hint v-log-l only does 4 1/3 stops over 18% grey", speaking for myself, I can't see how to use this information, and, also, I need a few good work examples to show that it is worth my time and effort to try it.

  • TrackZillasTrackZillas

    @Ralph_B Definitely right about the down conversion part. Can you imagine having the right down conversion plus 12bit 4:4:4 that would be the icing on the cake for me.

  • inqb8trinqb8tr

    Sorry for the off-topic, but did Nick say anything bout Moon T9? :)

  • TronTron

    Grading 10+ bit images on an HDR monitor for delivery in an HDR format is all that is required from a production standpoint. For all we know the camera may have its own HDR profile built-in... its all just speculation at this point.

  • WalkaboutcameraWalkaboutcamera

    Let's test what you guys know about HDR video, that is the single exposure version that relies on the dr of said exposure. Vlog-l just does not cut it for HDR.

    What kind of vlog will the gh5 bring us

  • Ralph_BRalph_B

    Regarding 1080p, the most valuable feature Panasonic could add would be a super high quality down conversion from the 4k sensor. They implemented this on the SDI output on the DVX200, and it is absolutely superb! I've worked with it personally. It's like having the fine detail of a 4k picture in a 1080 picture. Bit depth and chroma resolution are of secondary importance. Sure, more is better, but the quality of the down conversion is primary.

  • TrackZillasTrackZillas

    1080p 12bit 4:4:4 would be nice as well let's make it happen Panasonic you can do it. Does any one else think it would be a nice addition?

  • joetheprojoethepro

    I'm so impressed with these specs. Great to see 10/422 in consumer cameras now, especially in 4k. As long as they include vlog, this will be a revolutionary step. I never expected IBIS at a price point in line with the GH series.

  • EspenBEspenB

    The pre-presentation was a teaser for sure.

    The press text also says "The name '6K PHOTO' is tentative. " so marketing has gone bananas I presume. Since things don't seem to add up.

    Since 4:2:2 10 bit codec was rumored from before, the only real news was the body design (only as "mockup" I presume).

    I'm personally sad to see that the internal flash has gone since that makes under water photos with external TTL flash sync more difficult/impossible.

    The good thing is the possible return of the multi aspect ratio sensor, which will make wide angle shoots wider than before on the GH4. I shoot a lot of video with the GH3/GH4 under water with fisheye or 7-14 mm lenses.

    I mean if a still camera can have it, why can't a a couple of professional camcorders?

    Because main LSI is different and older.

    In old years Panasonic debuted their new LSI in the consumer ultrazooms. Now it is GH models.

  • PauloTeixeiraPauloTeixeira

    Pretty impressive specs the GH5 has.

    If only the Panasonic HC-X1 and he UX180 was going to have a 10 bit 4:22 recording mode as well. I mean if a still camera can have it, why can't a a couple of professional camcorders?

  • davedvdavedv

    I suppose if you call UHD (3840 x 2160) 4K and double that resolution 8K (7680 x 4320), then 6K would lie in the middle at 5760 x 3240 (which is 18 MP as mentioned in the Panasonic PR).

    That would make more sense and could work into a multi-aspect sensor like the GH2 had: https://www.flickr.com/photos/26325010@N02/5259897150/

    For example, if the oversized, multi-aspect sensor had a native 3:2 aspect ratio with 5760 x 3840 resolution (about 22 MP), then you might be able to end up with a 16:9 resolution of 5760 x 3840 and a 4:3 resolution of 5300 x 3975 or so (20+ MP).

    But it's still strange that they specifically mentioned 6000 x 3000 pixels and a 3:2 aspect ratio for the 6K Photo Mode. With how little actual information was in the press release, you think they could get the few facts it did contain correct.

  • Vitaliy_KiselevVitaliy_Kiselev

    @davedv

    We had similar discussion already as I remember.

    I think part can come from multi aspect sensor. And other part from marketing.

    Top Panasonic guy said that 6K is between 4K and 8K. And 8K must be present at least in one camera and one TV at 2020, this is how leaders said.

    So, all this strange "6K" weird mode "was marketing decision" (c) GC

  • davedvdavedv

    @EspenB You're right that the 6K Photo Mode numbers don't really make sense.

    For starters, 6000 x 3000 is a 2:1 aspect ratio, which is kind of odd. To get a 6K photo in 3:2 aspect ratio would be 6000 x 4000 (24 MP total). Or in a 4:3 aspect ratio this would be 6000 x 4500 (27 MP total). Which would seem to be a pretty big jump in total megapixel count (and pixel density) for a micro 4/3 sensor.

    If we assume the 18 MP number is accurate, then a 3:2 aspect ratio photo with that megapixel count would have dimensions of around: 5200 x 3466 An 18 MP 4:3 aspect ratio photo would measure around 4900 x 3675

    In either case, that's much closer to a 5K photo mode than than a 6K one.

    Yesterday presentation recording

  • EspenBEspenB

    Probably no more news until CES 2017 in 4,5 months.

    But seriously strange that even the photo MP is missing form the short introduction.

    We were for PV at the Photokina. I had an interview at Panasonic with Neil Lloyd-Meek from Panasonic England, who is a trainer for the sales people. The video of the interview will come. He repeated exactly what was said on the Press conference and to every other question regarding GH5 or anything going further of the Lumix system he said that he simply does not know it. He or they could not even say the planned month when the GH5 shall be available.

    I also met Nick Driftwood who said, and I belive it, he knows more but he can not say more due to his contract. Seems to be a high fine on him if he says something and belive me, I tried. What he DID say was, the the community will be very happy with the final result of the GH5 and that Panasonis does read very attentively Personal view and other forums to see what is demanded by the users. My "personal view" is, that the final list of the features of the GH5 is not finished and not decided and that they only published the specs that they are 100% sure that they can and will implement in the GH5 and that they see what else they can fit in.

    One more word about Nick Driftwood: For the forum, he seems to be on the "other" side, but for Panasonic he is still the "hack guy" and whenever something leaks out, he is still the first suspect for Panasonic.

    And directly to Panasonic: No, Nick did not say anything more than what has been published before dring the Panasonic Press conference.
