After more than two years without an update, the Panasonic GH-series compact system camera range is about to get a refresh. Panasonic has taken what video-makers love about the GH4 and improved on it with the GH5, which is due to hit the market next year.

For the past few years, the GH4 has been one of the most popular pro-sumer 4K video cameras. That's partly down to the fact that it was among the first to record 4K video on to an SD card, rather than an external drive. It's also because - compared to a lot of other similar cameras - it was good value for money.

Digging down in to specs that are available, it seems the GH5 will comfortably take on its predecessors mantle. 

Panasonic has announced that its GH5 will record smooth 4K video at 50p/60p, but will also reproduce 4:2:2 10-bit 4K video. That essentially means it's not quite pro cinema level in terms of colour, depth and detail, but it's easily high enough quality for TV. 

It's clear then that - as well as getting its high-end YouTube producer types - it wants to sell its Lumix MFT cameras to professional videographers in traditional media. 

As well as the high quality 4K video capture, the GH5 features 6K photo, which is an 18-megapixel still image extracted from high quality video. The end result is an image with nine times the detail of full HD. You'll also be able to extract a 4K photo from videos shot at 60 frames per second. 

There's still a lot we don't know about the GH5. For instance, there's no word on the design, build or materials, neither is there any detail on the sensor size. 

The GH5 will be available to buy at some point in the first half of 2017. Pricing hasn't been announced yet, but we'd expect it to cost upward of £1000. The GH4 launched at around £1300 body-only, so it'd make sense for the GH5 to launch at a similar entry point.
