Fujifilm xf 23mm f 1 4 r lm wr vs ttartisan 23mm f 1 4?
Both lenses are 23mm f/1.4 primes for APS-C cameras, and on a Fujifilm X body they frame and blur the same way: like a 34mm on full frame, with depth of field about that of f/2.1.
The big difference is focus and mounts. The Fujifilm XF 23mm f/1.4 R LM WR has autofocus and fits only the Fujifilm X mount. The TTArtisan 23mm f/1.4 is manual focus only, but it fits six mounts, including Sony E, Nikon Z and Canon RF.
If you shoot Fujifilm X and want autofocus for people or street work, I'd get the Fujifilm. If you want a manual-focus lens you can move between bodies, or you're happy to focus by hand, the TTArtisan is the more flexible choice. For more on picking a fast standard prime, see your first lenses.
