Best wide angle lens for the fujifilm gfx 50s?

For wide angles on the GFX 50S, I'd start with the Fujifilm GF 20-35mm f/4 R WR. It covers roughly 16-28mm on full frame, which is a sensible everyday range, and it's weather sealed.

If you'd rather carry a prime, the Fujifilm GF 23mm f/4 R LM WR works out to about 18mm equivalent. For the widest view, the Laowa 19mm f/2.8 Zero-D GFX gives about 15mm equivalent, and it's a faster lens than the zooms.

The Fujifilm GF 19-35mm T3.5 PZ OIS WR is the one to pick if you shoot handheld in dim light. The GFX 50S body has no stabilisation, so a stabilised lens helps at slow shutter speeds.
