Here you can find a list of all the lenses made by Fujifilm for the X-mount system.
The lenses will be listed as Primes, Zooms, and then Cine lenses, from the widest angles to the narrowest angles. Zooms will be listed according to the widest angle available, rather than the narrowest or full zoom range, so for example the 16-80mm will be listed before the 18-55mm lens, since it has 16mm as the widest compared to 18mm.
You can find a list of third party X-mount lenses on the corresponding page.
