Dpreview published their Panasonic FZ2500/FZ2000 review:

It is a well-designed enthusiast bridge camera focused on video, and it offers capture tools that you won’t find on any other camera in its class. 4K video quality is excellent, though there’s a substantial crop factor, essentially knocking out the wide end of the lens. Still image quality is decent, though it’s hampered by a so-so lens and JPEG engine that could use a tune-up. If you’re a videophile then it’s a top choice. If not, there are cheaper options out there.

LUMIX GH5 High ISO grading test [4K] from Martin Wallgren on Vimeo.

This is a impressive GH5 test made by Martin Wallgren. This is what he writes:

This is my first uploaded footage that I shot with the GH5 pre-production model I got just recently. I shot the footage handheld at ISOs between 3.200 and 10.000, quick grade with FilmConvert Pro in FCPX.
Since I don’t have V-Log activated just yet on the camera, I was shooting this with a tweaked CineLike V profile, see below for details. I discovered to my surprise while goofing around with my anamorphic lens that the camera seem to deliver even cleaner looking footage at the highest ISO settings by shooting in any of the 4K 8bit 24/25/50/30/60p Anamorphic 4:3 modes. I really don’t know the reason behind this difference, but the footage in anamorphic mode is downscaled to 3328×2496 from full readout resolution, and there may be some sort of sweet spot for the internal processing. I cropped and upscaled the footage to a custom 3840×1620 2.35:1 timeline in FCPX. No de-noising or stabilisation was applied in post.
Download the ProRes Proxy “Original” if you want to have a closer look with less compression artefacts.
I am hoping this will put an end to all the low-light, dynamic range and sensor-size related criticism that a bunch of non-users of the camera have been discussing lately on social media. The GH5 is a major improvement over the GH4, the G80 and any other Micro Four Thirds camera produced to this date, and in all kinds of ways. While this footage is not all clean, it’s a way of showing what you can do in reality with this camera.
This was shot with the new LEICA DG Vario-Elmarit 12-60mm f/2.8-4 that will also be available as a kit lens with the GH5. I encourage you to imagine what you can shoot with this camera at these ISO levels with a really fast prime, such as the Voigtländer Nokton f/0.95 set of manual lenses or Metabones SpeedBooster Ultra adaptor and fast Canon/Nikon glass (all of which will benefit from the 5-axis sensor IBIS).
Picture Profile: CineLike V 0/-5/-5/-5/0, Master Pedestal +10, Luminance Level 0-255.
