What lenses should I buy for the sony rx100 v?
The Sony RX100 V has a built-in lens, so there's no way to add others. Its 8.8-26mm f/1.8-2.8 zoom covers roughly 24-69mm on full frame, which handles most everyday shooting, from wide street and travel scenes to portraits.
If you want to change lenses, you'll need a different camera. For most people starting out, I'd suggest a mirrorless body with an APS-C sensor and its kit zoom, then adding lenses as your interests grow. The first camera guide explains why that route makes sense, and the RX100 V page has the full specs.
