Pearl Beach: Atomos Shogun and Sony a7S 4K test by Matt Allard from Dan Chung on Vimeo.
Newsshooter shared that video and on the full 4K video can be downloaded on their Vimeo page:
As far as the image is concerned the a7S does seem to exhibit more noise in 4K mode versus it’s output in HD. This is most likely the camera and sensor that are doing this – all the recorder is doing is capturing the output from the HDMI as it receives it. At super high ISOs the noise it quite obvious before any kind of post noise reduction is applied. It would also appear that the crop mode is noiser than the full frame – as you would expect. You can download the video above for yourself from Vimeo if you want to make your own judgements.
