Hands-on with the Sony Cyber-shot DSC-RX10 IV

Introduction

The RX10 IV, as the name suggests, is the fourth in Sony’s series of 1″-type sensor, long zoom compacts. The Mark IV is the first to offer phase detection autofocus alongside a series of changes designed to boost the speed and capability of the camera, for both stills and video shooting.

Sony is adamant that the camera is much more than an RX10 III with an RX100 V sensor in it. Let’s take a look at what the latest version brings.

Autofocus

One of the biggest changes in the Mark IV is the addition of on-sensor phase detection autofocus. There are a total of 315 phase-detect points, which cover 65% of the total sensor area. This is a significant update as it should eliminate the RX10 III’s need to hunt for focus, which was a particular problem at the long end of the zoom.

In addition, we’re told the camera has “exactly the same” processor as used in the company’s flagship sports camera: the a9. This means the RX10 IV has the same autofocus algorithms for subject tracking and the improved Eye AF mode we saw on the a9.

Touchscreen

The RX10 IV also becomes the first camera in the RX series to gain a touchscreen. This can be used for tap-to-focus in both stills and video mode. In video mode it is designed to offer a smooth focus transition between subjects which, combined with on-sensor PDAF, should make it relatively easy to shoot good-looking video without having to worry about manual focus.

The screen can also act as an AF touchpad when the camera is held to your eye, with the option of limiting the active area of the screen to one of nine regions → continue…
