Sony RX100 IV builds on its predecessor (pictures)

The camera body is pretty much the same as the RX100 III's, including the same 24-70 f1.8-2.8 lens.

The camera is one of the smaller choices in the enthusiast-compact class.

The pop-up, pull out viewfinder keeps the camera quite small when retracted.

Even when up the viewfinder is pretty small.

These remain unchanged from its predecessor.
