The Panasonic GH5S was added to the DPReview Studio scene and the results are less than impressive. In RAW I would say the GH5S holds its own until 6400ISO and in JPEG 12,800ISO, but past that I wouldn’t find the images useful. The performance in video should be slightly different, but these results make me highly doubt any claims that the Panasonic GH5S can beat the Sony a7SII at any task beyond size and price.
