The RX100 IV continues the line's tradition of packing as much image and video quality into as small a package as possible. The RX100 IV is also an incredibly responsive camera; fast and ready to churn out high quality images and video with tools designed to help you achieve your vision.

Some of the best image quality in any compact camera; ever; Impressively sharp 24-70mm equiv lens remains usefully bright throughout zoom range; Impressive image stabilization for stills; dramatically effective in video; Well implemented Eye AF system tracks subjects well; Superb high resolution...

Extensive feature set overwhelms the user interface; As a twin-dial camera; could be programmed better to make full use of both dials; Expensive compared to rivals; Short battery life; Lock-on AF can be unpredictable and laggy; Lens range will be limiting for some users; No microphone socket,...

The RX100 has long been Sony's flagship Cyber-shot compact. It's the leader in its point-and-shoot squad, gathering up cutting edge features and high-performance components and stuffing them neatly into a pocket-sized camera.

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. Though it's more expensive and adds a plethora of video capabilities, it's pretty much delivers the same photo quality in the same body.

A nice choice if you're looking for an advanced compact with class-leading video capabilities, the Sony Cyber-shot DSC-RX100 IV is a little expensive if you just want a good camera for shooting stills.

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.

I was always a little hesitant to pay that much for 'Sony' camera... I love this camera! I need it something small and handy to carry always with me. I own couple good DSLR's by NIKON but I was too lazy to carry them with me all the time.

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.
