Packed with premium features and with a price tag to match, the Sony RX100 IV is a formidable compact camera.

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.

The Sony Cyber-shot RX100 IV proves, once again, that size doesn't matter.

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.

Sony’s RX100 series of premium-quality compacts for enthusiasts has proven hugely popular and garnered worldwide acclaim. The RX100 IV is the fourth iteration, and like the model it replaces, has a stabilized Zeiss Vario Sonnar T* 24-70mm (equivalent) f1.8-2.8 zoom and pop-up EVF, but in place of...

The RX100 IV gains some headline-grabbing features such as high frame rate and 4K video but it's the smaller features that most impressed us. Continuous eye tracking, fast Raw burst modes with AF, and small user-interface changes have made the Mark IV the most responsive and enjoyable RX100 yet.
