Beating the “Battle with Heat” for Even Greater Innovation in Professional Video Performance – LUMIX GH5


Faced with a Heat Problem for Unlimited Video Recording and Ultrahigh Motion Picture Quality

The GH5 achieved the world’s first 60p/50p video recording (*2) and the world’s first 4:2:2 10-bit 4K 30p/25p video recording (*3) while also enabling unlimited video recording. However, heat inside the camera body became a large problem for these achievements. The amount of video data necessary for the GH5’s ultrahigh picture quality is more than 3 times that of the GH4. As data increases, the power consumption also rises and the temperature inside the camera greatly increases. It would be easy to disperse the heat by increasing the size of the camera body, but we insisted on maintaining the size and grip that were so popular with the GH4. As a result, GH5 development became a “Battle with Heat.”

The amount of 4K video data increased greatly with the GH5
