Fujifilm xf 18mm f 2 r vs ttartisan af 17mm f 1 8 air?

Both are small APS-C primes at almost the same focal length, so the choice comes down to mount and light.

The Fujifilm XF 18mm f/2 R is one of the three original X-mount primes, and it's small and light. It only fits Fujifilm X cameras. If you shoot Fuji, I'd pick it for everyday carrying.

The TTArtisan AF 17mm f/1.8 Air is a little faster at f/1.8 and a touch wider. It also fits Sony E and Nikon Z bodies, so it's the one to choose if you might switch systems or already own those. Neither lens has stabilisation, so you'll rely on the light for low-light shots.

For how these apertures compare in blur, see the focal length converter.
