What lenses should I buy for the sony a7s ii?
For a Sony a7S II, I'd start with a fast everyday zoom. The Sony FE 24-70mm f/2.8 GM II covers most daily shooting and works well in dim rooms, which suits a camera with only 12.2 megapixels.
For wide scenes and night work, the Sony FE 14mm f/1.8 GM is a strong pick. If you shoot people or events at a distance, the Sony FE 70-200mm f/2.8 GM OSS II is the one to add.
If you want to spend less, the Sony FE 28-70mm f/3.5-5.6 OSS is a light, simple kit zoom. Before you buy, check the what to buy in three questions guide, since you'll be buying into the Sony E mount for years.
