As expected, Panasonic has unveiled its much-anticipated successor to the Lumix GH4, the GH5, and the focus is once again on video. The flagship model, set to arrive in mid-2017, ups the video capture capability to 6K at 30fps and brings 10-bit, 60fps shooting at 4K. 6K capture may sound like overkill, but it'll give filmmakers more options in terms of reframing, and allow for a better final 4K image. The GH5 will also be much better for slo-mo shots compared to the last model, which topped out at 30fps. At the same time, 10-bit capability will let professional videographers capture billions instead of millions of colors, giving far more latitude for color correction.
The camera will pack Panasonic's new 18-megapixel sensor, which supports up to 8fps in regular burst mode, or up to 60fps in Panasonic's "4K Photo" mode. The company also promised to add 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, 6K capture and 10-bit video are huge additions, and should put the camera at the top of the list for videographers looking for new gear in 2017.
