Sony has announced a 4K ultra-compact action camera that it describes as "the world's smallest and lightest".

The Sony RX0 II improves on its predecessor by adding internal 4K recording, new image stabilisation tech and a tiltable display that can help with video selfies.

Like the original, the RX0 II is waterproof, dustproof, shockproof and crushproof. It sports a 1.0-type stacked 15.3-megapixel image sensor and a Zeiss 24mm fixed wide-angle lens.

It comes with a microphone jack and included shooting grip that makes it easy to hold in the one hand.

The in-body electronic image stabilisation is designed to steady footage when mounted or handheld. And, when exported to Sony's proprietary Movie Edit add-on application, the clips can be steadied further through post-shoot processing.

As well as 4K 30fps video, the camera is capable of shooting slow motion footage at up to 1,000 frames per second.

Its ISO range for stills and video is 80-12,800. Still photography can be shot at up to 16fps.

Interval shooting is also supported and can be edited through Sony's Imaging Edge desktop application.

The Sony RX0 II camera will be available from May, priced at approximately £730 in the UK and €800 in Central Europe.
