The RX100 VI is something of a departure for the RX100 series: offering a more extensive zoom range but giving up some of its large sensor's low light ability by pairing it with a less bright lens.

Anyone needing fast AF; good video; sharp images and a flexible zoom range in a pocket-sized package

Anyone seeking the best possible image quality in dim light or with moving subjects

Like its predecessor, the RX100 IV is expensive, but it's also the best compact camera you can buy.

1-inch; 20.1MP "stacked" CMOS sensor; Outstanding photos and videos; 4K and super-slow-motion modes; Improved EVF

Even pricier than before; Limited focal range; Mediocre battery life

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, Lens doesn't offer as much telephoto reach, Macro performance not quite as good as some...

The Sony Cyber-shot RX100 IV (M4) is less of an clear upgraade over its predecessor the RX100 III (M3) than a forked alternative; for a variety of reasons, I'd classify it as an advanced compact for video enthusiasts rather than a straight-up advanced compact, at least until the price drops a bit.

Great video features to supplement its 4K capabilities distinguish the Sony Cyber-shot RX100 IV from the rest of the advanced-compact pack; It also retains the nice design perks, like a popup electronic viewfinder, of the earlier RX100 models

Like its predecessor; the autofocus system could be more consistent and the battery life has gotten even worse

Conclusions Sony has added features to its RX100 line with each new generation. The Cyber-shot DSC-RX100 IV is a more iterative update to its predecessor in terms of imaging capability, with the main benefit being a faster burst capture rate.

Wide-aperture zoom lens; 1-inch image sensor; Strong low light performance; 16.1fps burst shooting; Customizable controls; Large, tilting LCD; Pop-up OLED EVF; Quick autofocus; Raw shooting support; Wi-Fi with NFC; Super slow-motion video; 4K recording

Expensive; Short zoom range; Omits hot shoe; External charger not included

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 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

The RX100 IV becomes one of the smallest traditional compacts with 4k video, and the slow motion modes from 4x to 40x are simply fantastic. Whether you're a film-maker, someone who analyses sports motion, or simply enjoys footage of your kids or pets running and splashing around, the RX100 IV...

Simply put, the Sony RX100 IV is the best pocket camera money can buy today. Of course, it takes a lot of money to buy this camera, which is probably the only criticism that I have for the RX100 IV. At $950 retail, the potential audience is somewhat limited by the size of one's wallet.

The most significant changes are the slow motion video feature and the high speed shutter speed of 1/30,000, along with a new auto-focusing system. Sony has kept the compact size and who can fault it for keeping a winning formula
