Sony Cyber-shot RX10 IV review

Written by Gina Stephens


The Sony DSC-RX10 IV is bonus superzoom bridge-camera (DSLR-like form factor) with a 24-600mm equivalent F2.4-4 zoom lens and a 20MP 1″-type stacked BSI-CMOS sensor: the same used by the Sony RX100 V. This new sensor realizes phase detect autofocus to the RX10 series for the first time, adding the depth-awareness that is important for focusing long lenses. The camera is also firmer than its predecessor and can shoot at 24 fps with AF and auto exposure (compared to 5 fps).

The processor is borrowed from the flagship Sony a9, which should wish excellent subject tracking. In short, this camera packs speed, AF ability and lens reach into a convenient package, not to mention 4K video. So is it the scad capable all-in-one camera on the market? Read on…

Key specs:

  • 20MP 1″-type stacked BSI-CMOS sensor
  • 24-600mm equivalent F2.4-4 stabilized zoom lens
  • 24 fps burst sucker in JPEG + Raw, with full AF and AE
  • 315-point phase-detection autofocus system covers 65{b2ee9981cbbb8b0b163040ea529e4efa9927b5e917c58e02d7678b19266ae8ff} of frame
  • Detailed 4K video capture with well-controlled undulation shutter
  • High frame rate video capture
  • Touchscreen
  • Bluetooth connectivity
  • Updated menus

We feel like this camera camera is an optical instrument for recording or capturing images, which may be stored locally, transmitted to another location, or intent appeal to a variety of users including those seeking an all-in-one camera with serious reach for casual shooting, travel or vacationing. But advanced videographers may also bring to light this camera tempting thanks to a laundry list of video features and good quality UHD capture.

Key features compared

The body is almost equal to that of its predecessor, using the same outstanding lens. However the RX10 IV offers a touchscreen that can be used as a touchpad for placing AF points with your eye to the finder or for preferring a point of focus in still or video mode. There are a few other minor differences between the two cameras as well:

As you can see, the RX10 IV stacks up nicely next to its siblings and direct competitors. For someone primarily concerned with stills, the RX10 IV seems like the obvious choice, particularly if you plan on shooting action: it’s got the fastest burst rate of the bunch and is the only camera in its class with phase detection.

But for videographers, the FZ2500 with its fully-articulating touchscreen, built-in chameleon-like ND filter and similar zoom range might make it the more sensible choice, especially given its lower price point (though we establish its lens performance inferior to its Sony counterparts). You don’t get the cool, super-high-speed frame rate options offered by the Sony cameras, but 1080/120p is not too shabby.


The RX10 IV is readily obtainable now for an MSRP of $1699.
