perhaps a buyer beware comment, but i was unaware i was purchasing a non-USA unit without the USA Sony warranty. perhaps it was stated somewhere, but i did not see it. with the above said, camera works as expected. great pictures, especially for the camera size, OK battery life.

Because of brand loyalty, I was waiting for Nikon's DL series to be introduced. I was excited about the 120 fps slow motion and 4K capability. And the $650 price tag fitted right along my budget. Needless to say, I was very disappointed when it was delayed numerous times and finally declared dead.

I purchased this packaged to replace a 4-years old Lumix LX-5. The sd cards are not the fastest, but good enough unless you need to take super high definition movies. The batteries and charger are helpful since the camera wear them out fast.

High price; Little grip at the front; Some vignetting; Shorter battery life

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

It's 2015 and there's an argument that the compact camera is obsolete in the face of advancing smartphones. The Sony Cyber-shot RX100 IV is the absolute antithesis to that; a high-end, pocketable compact with large 1-inch sensor and 24-70mm f/1.8-2.8 equivalent lens.

The pocketable compact to beat; excellent image quality; built-in electronic viewfinder; fast aperture lens; customisable control ring

Hugely expensive; autofocus performance could be yet faster; still no touchscreen; limited bump over third-gen predecessor

I should point out that I bought this camera at a reduced price during a special offer. I'm not entirely convinced I'll be keeping it, but I certainly wouldn't be if I had paid the regular price. Anyway...

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.
