As a result, the GH5 will be allow better slow-mo than the last model, which topped out at 30fps. At the same time, 10-bits will let professional videographers capture billions instead of millions of colors, giving far more latitude for color correction.
As mentioned, the camera packs Panasonic's new 18-megapixel sensor, which supports up to 8fps in regular burst mode, or 60fps in Panasonic's "4K Photo" mode. The company eventually plans to release future models with 8K, 32-megapixel capture in time for the 2020 Tokyo Olympics.
We don't know a lot else about the GH5, since we've only seen an early prototype, and it's not set to go on sale until the middle of next year. However, 10-bit, 60fps 4K video is good news for filmmakers, and should put the camera at the top of the list for many in 2017.
Update: The headline originally said that the GH5 would support 6K, 30p video, based on one of Panasonic's slides (above). However, the mode is only intended for burst photo shooting. The article has been updated with the correct information.
