What lenses should I buy for the sony rx10 v?
The RX10 V doesn't take interchangeable lenses. Its 8.8-220mm f/2.4-4 zoom is built in, which covers roughly 24-594mm on full frame, so there's no lens to add. If you want to stretch reach beyond that, you'd need a different system camera, not an accessory for this one.
Check the Sony RX10 V page for the full specs. If you're still deciding between a fixed-lens compact and a camera with swappable lenses, your first camera explains the trade-off. The three questions to ask before you buy are also a good place to start, especially the one about which lenses you'll want in a couple of years.
