Introduction:
The Sony DSC-RX10 IV is premium 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 brings 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 faster 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 mean 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 most capable all-in-one camera on the market? Read on...
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, especially 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 variable ND filter and similar zoom range might make it the more sensible choice, especially given its lower price point (though we found 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.

Key features compared
The body is almost identical 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 selecting a point of focus in still or video mode.
