What lenses should I buy for the sony a1?

For the Sony a1, I'd start with a standard zoom and a telephoto zoom, then add wide-angle later if you need it. Everything below is a Sony E-mount lens that fits the a1.

If you want to keep the budget down, the Sony FE 24-105mm f/4 G OSS covers a similar everyday range in a smaller, cheaper package.
