Best wide angle lens for the sony a9?

For the Sony a9, I'd start with the Sony FE 16-35mm f/2.8 GM II. It covers the usual wide-angle range in one zoom, and a constant f/2.8 keeps your exposure steady as you zoom, which matters when light is changing. If you want something lighter and faster, the Sony FE 14mm f/1.8 GM is a strong prime for low light and dramatic perspective, though you'll have to move your feet to frame. For a budget option, the Sony FE 16mm f/1.8 G is a simple, fast wide prime.

Before you buy, check how the aperture behaves across the zoom range. As the lenses guide explains, cheaper zooms get darker as you zoom in, so a constant aperture is worth paying for if you shoot in dim places. You can see every wide option that fits the a9 on its camera page.
