Fujifilm GF 45mm f/2.8 the perfect lightweight, medium format wide-angle lens

I recently purchased the Fuji GFX 50S and I needed a couple of lenses to get me started. I knew I needed a portrait lens and Fuji hit it out of the park with the 110mm f/2, one of my favorite portrait lenses of all time. But I needed something wider for environmental portraits and potentially some landscape work.
