Is the sony rx10 ii worth buying used?
The Sony RX10 II is a sensible used buy. It has a built-in 8.8-73mm f/2.8 lens that frames like 24-198mm on full frame, and a 1-inch, 20.1-megapixel sensor. Because it's a fixed-lens camera, you're buying the whole system in one body, so there are no lenses to track down later.
Budget for a new genuine battery. Old batteries lose capacity, and that cost can be a real part of the total. The buying used page explains why a model a generation or two old is often most of the camera for much less money.
If you'd rather have the newer model in the same line, the Sony RX10 III uses the same 1-inch, 20.1-megapixel format and was announced in 2016, a year after the RX10 II.
