What lenses should I buy for the sony a7 iii?
The a7 III is a full-frame camera, so any lens on its list frames as marked. If you don't have a particular subject in mind, I'd start with a standard zoom and add to it later.
- Sony FE 24-70mm f/2.8 GM II is my everyday pick. It covers most of what you'll shoot, from people to street to travel.
- Sony FE 16-35mm f/2.8 GM II is the one to add for landscapes, interiors and architecture.
- Sony FE 70-200mm f/2.8 GM OSS II is the choice for portraits, sport and wildlife, if you want reach.
If you want to keep costs down, Sony FE 28-60mm f/4-5.6 is a small, light starting point. Before you buy any of these, check the three questions page, and if you're buying the body used, read buying used first.
