Panasonic Lumix GH5S review

Panasonic’s new mirrorless camera is designed for video first and stills second, so what does this mean for photographers?

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.
