Panasonic GH5S lab tests
We compared the lab results from the GH5S against those of three key 4K-shooting rivals: the Canon EOS 5D Mark IV, Panasonic GH5 and Sony A7S II. Our lab tests are carried out on still images.
Colour error
With a colour error of just 0.3, the GH5S produced an almost perfect score, which put it well clear of its key rivals – though any video grading (editing) carried out later would swallow up the differences.
Signal-to-noise ratio
In the lab, the GH5S shows much lower noise levels than its rivals, but real-world testing suggests this is achieved only with very heavy noise reduction and detail loss.
Dynamic range
Unusually, the GH5S offers a consistent 12-stop dynamic range across the full test ISO range. We have occasionally seen this before with Micro Four Thirds sensors.
