Panasonic Lumix GH5S £2,199/$2,298

Great for 4K video, less so for stills

Panasonic has made 4K crossover cameras its speciality – but with the GH5S it’s gone a step further, sacrificing outright resolution for high-end video features. The sensor has only 10 million pixels, which dents its appeal for stills photography, but is ideal for 4K, especially as this is a ‘multi-aspect’ sensor that can shoot in the 17:9 Cinema 4K ratio, 16:9 for 4K UHD and regular 3:2 and 4:3 stills ratios using the maximum sensor area.

Uniquely amongst ‘crossover’ cameras, it can capture 4:2:2 10-bit video internally to suitably fast SD cards. Most rivals can only capture 8-bit video. The GH5S also comes with Panasonic’s V-logL log mode pre-installed for extra dynamic range.

Performance

Performance is first rate, capturing great clarity, contrast and colour straight out of the box. Panasonic says the sensor readout is 1.3x faster than the GH5, but there is a still a rolling shutter effect with fast panning.
