GH5 Panasonic camera, from anticipation to love or hate

  • Having been using the GH4 externally (ninja Assassin Pro res) and internally, my one wish is for the GH5 to have an 8bit 422 mode. I think the really benefit using V-Log L externally seems to be the 422, not the 10 bit part. 10 bit is 'visually' the same as 422 8 bit. 10 bit benefit only comes when looking at extreme gradients. Internal 422 8 bit would be a nice compromise between size and colour info.

  • Using terms like 'filmic' and 'Colour harmony' in a technical test reveals a lot about the people doing the test. Concluding that 10 bit recording has no advantage over 8 bit is quite astounding. Using a LUT to assess v-log quality is not the only way to do it and can be seriously flawed if not doing a strictly controlled test. The skin tone comparison is laughable.

    PS They used the Panasonic VARICAM Vlog LUT! What idiots!

    I can't call it "lab results", as they call it. It is some unsystematic mumbling.

    Considering dynamic range test, someone need to tell them that you don't need all this expensive backlight targets to determinate dynamic range of digital sensors. And someone else must tell them that dynamic range is different for different color channels and is dependent on sensor temperature. As far as I remember they constantly had issues with dynamic range measurements.

    Charts are not properly balanced. Comparing details can be utterly misleading as you do not know algorithms underneath that can have different degree of sharpness applied.

    Metabones pitching all around.

    And again, new traders of LUTs, this time they ask for your emails as price.

  • Anyone aware of any firm stock updates or release dates yet? I know the 20th of this month was listed, just wondered if anyone had heard earlier/later?

  • Better skin tones on the BMPCC

  • I notice several people have been mentioning that they find the GH5 image preferable to the GH4 image. What about the GH5 image as compared to the G7, G85 and the GX85? I am looking to obtain 2 m43 cameras to record 4K interviews and I'm trying to determine if the indoor low light and skintones on the GH5 are better enough to warrant the much higher price for a 2 camera setup?

  • I wonder why nobody tests GH5 18 Mpixel 10bit HEVC video. It should be very good when down scaled properly to 4k.

  • @CameraRick I believe that was earlier versions of the firmware. My GH4 footage averaged 95mbps

  • I agree that it definitely would benefit from a bit more bits per second. Hopefully they will deliver the higher bitrates when they finish this cat and mouse play with speedy sd cards availability/pricing.

  • @inqb8tr When memory serves me right, the GH4 never really was at 100mbit, more 80, and the GH5 (at least that Neumann footage) was a bit above 150mbit, more 170-200mbit. That can of course be because of the Beta FW, but it seems to be double at the moment. That should fetch the additional info quite well :)

    I don't know, I don't feel it's that sort of NR artifacts, to me it looks more like Codec smudge of too little bandwidth. But I don't know for sure, obviously. What I know is, I feel that the GH5 produces a MUCH more appealing image :)

  • @CameraRick

    I think that more apparent detail in high ISO 10 bit mode is just due to lesser noise processing. Just by looking at the high ISO 8 bit footage you can tell that there are NR artifacts, specially softness of fine details.

    Didn't do the maths, but I think that the 150mbps codec for 10 bit is actually lower bandwidth than the 100mbps is for 8 bit recording.

    If the NR could be turned off it would be a fair comparison between how noisy the sensor really is at any mode. Still looks a lot better then the GH4, and besides the noise and details, there is lot less color change/blockiness.

  • @inqb8tr

    did you also notice that there's a lot more detail? My wild guess is that the 10bit 422 codec of the GH5 with its higher bandwidth is able to capture more actual detail (which includes noise) than the GH4 where it gets smudged away. In his beard, it's really awful on the GH4.

    However, even though it appears to be noisier, the footage will clean up a LOT better than the GH4 is you really want to, with noise reduction in post

  • GH5 10 bit is noisier than 8bit, must be too much data for the internal noise reduction processing.

  • GH5 ISO lowlight test 8 and 10 bit comparison as well as to the GH4

  • For the focussing testing:

  • The GH5 certainly looks like a nice camera but I think the GH4 still has a lot of life left as a compact 4k camera. It's lighter and still produces a great image when used with care and skill, unlike Kai, who manages to shoot some very ordinary looking video with the GH5.

  • Kai's 'pre-review' is boring. He doesn't bring any interesting news or views, and his jokes have become boring too.

  • The James Miller footage looks great. Nice highlight handling and the skin tones look very natural.
