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.

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

Sony's pocket rocket is a compact with almost no compromises

Excellent image quality; 4K videos; Brilliantly fun HFR mode; Pocket-sized

Prohibitive price; Limited zoom range

Whereas its closest competitors, the Canon G7 X and Canon G5 X make you choose between an electronic viewfinder (on the G5 X) and a truly pock-sized design (the G7 X), the RX100 IV incorporates a high quality viewfinder that retracts into the camera when it's not needed.

An EVF, 16fps shooting and 40x slow motion are desirable features, but we'd have liked a touchscreen to speed up focusing, so it's four stars for Features & Build.

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...

The Sony RX100 Mark IV is one of the best compact cameras made till date, providing full manual control and good dynamic range, thus making it a very versatile camera. However, the lack of touchscreen input and a mis-functioning autofocus mechanism means that it has its limitations.

Small; fits in trouser pockets; Good build; Excellent image quality; Good dynamic range; Extensive manual controls; WiFi connectivity; Excellent electronic viewfinder

Restricted range of lens; Autofocus mechanism does not work well; Weak battery stamina; No touch input; WiFi configuration is not the easiest

The Sony RX100 IV is a high compact really extraordinary range. It enhances the experience of the previous incarnation, especially in terms of operating speed and video capabilities.

I use this camera along with the Sony A7S for family and travel. 4k video is stunning. I use a light tripod where possible and the video is great. 4k codec is easy to edit in Premiere Pro. Slow motion clips although short look good.

The RX100 IV takes superbly vivid, crisp and striking images that can match up to and in some cases surpass even high end DSLRs. It shoots real 4K video and is the world's first camera to have a 1.0-type stacked CMOS image sensor.

4K video shooting up to 960 fps; Super slow and super-speed shooting; Great bright condition & low light condition shooting; High speed continuous shooting at 16 fps; 180 degrees tiltable LCD Screen

Poor auto-focus system due to lack of touchscreen; Poor battery life; Unable to shoot in raw in certain camera settings
