As you can see from this review, the Sony RX100 IV is a little powerhouse that is not only capable of delivering outstanding image quality for its sensor size, but also superb 4K and slow motion video.

The RX100 Mark IV is the fourth iteration of Sony's popular fixed-lens, pocketable digicam line, which was launched in June 2012. All four cameras have featured 13.2 x 8.8 mm with effective resolutions of around 20 megapixels, pocketable bodies with retracting Zeiss Vario-Sonnar T* zoom lenses and...

There is one area where the new camera has gone slightly backwards, and that's battery life. The RX100 IV is quoted at a fairly lacklustre 280 shots compared with the Mark III's (albeit not that much better) 320.

High-resolution viewfinder; Tilting screen; Large sensor; 4K video

High price; No touchscreen; Limited raw functionality

Sony keeps upping the ante with their RX100-series of premium compact cameras. Now on its fourth-generation model, the Sony RX100 IV introduces a host of performance-oriented improvements and new features, including 4K video capture, 16fps continuous burst shooting and a very fun high frame rate...

Vastly improved burst speeds with deep buffer; Great performance with very fast autofocus; Very high resolution gives lots of detail in good light; High ISO noise levels much better than most pocket camera rivals; High-quality 4K video with uncompressed HDMI out; Super-fast High Frame Rate video;...

Pricey for a compact camera; JPEGs can look over-processed at higher ISOs; Lens doesn't offer as much telephoto reach; Battery life not as good as predecessor; 24-70mm-equivalent lens can feel limiting

The Sony RX100 range of compact cameras has won plaudits from critics and consumers alike over the past couple of years, finding favour as a model which you can slip into your pocket or handbag when you don't want to carry a DSLR or CSC around with you.

The latest version of Sony's popular RX100 range of compact cameras, the Sony Cyber-shot DSC-RX100 IV, features a brand new sensor design. It retains the same pixel count as its predecessor, at 20.1 million, but a new stacked Exmor RS design sees a DRAM memory chip attached to the sensor itself for...

The Sony RX100 IV is the fourth instalment in what has become our favourite compact camera series. Since its beginnings in 2012, it has given us pocket-friendly models that offer image quality good enough to satisfy high-end DSLR-wielders on those days when taking out a large camera just isn't on...

Pocketable size; Excellent shooting speed; Versatile video; Great image quality at lower ISOs

Intimidating price

Back in 2012 Sony redefined expectations for small cameras by fitting a large, high resolution 20.1-million-pixel 1-in sensor into the pocket-sized RX100. Every year since then, it has taken its advanced point-and-shoot compact and improved it for the better.

+ Impressive resolution for a camera so small; + Advanced video capabilities including 4K and slow motion recording; + 16fps continuous shooting; + Electronic shutter (allowing shutter speeds of up to 1/32000sec to be used; + Built-in Wi-Fi & NFC connectivity; + USB charging

Reduced battery life (280 shots; No touchscreen functionality; No rubberised handgrip; Small buttons

The improvements that have been made to the RX100 IV are centred around its new sensor. The repositioning of the high-speed circuitry has resulted in it being able to shoot faster and offer unique video capabilities such as high frame rate mode that allows you to record super slow motion footage.
