Is the fujifilm gfx100 good for wildlife?

Honestly, the Fujifilm GFX100 isn't my first pick for wildlife. It's a medium format body built for detail, and wildlife depends on reach and speed, which medium format gives you the least of. Its 0.79 crop factor means a 500mm lens frames like about 395mm, which is useful but still short for distant birds.

If you want to try it anyway, these are the lenses I'd look at:

Buying lenses used is the cheapest way to test this. For the bigger picture, see wildlife and sport.
