Is the sony rx10 iv worth buying used?

Yes, I think the RX10 IV is a good used buy. It's a fixed-lens bridge camera with a 24-600mm-equivalent zoom and a 1-inch sensor, so one lens covers most of a safari. Its successor, the Sony RX10 V, has a stacked sensor, a faster processor and newer autofocus. That makes the IV one generation old, which is where buying used pays off: you get most of the camera for less money.

Before you buy, budget for a new genuine battery, since old batteries lose capacity. If you're new to cameras, your first camera has advice on handling. Hold one first if you can.
