Verdict

The Viltrox AF 23mm f/1.4 XF may not be as good as the competing Fujinon lenses but it easily beats both of them in terms of value. At $329/349EUR, it is almost shockingly priced for such a fast lens. Therefore you may forgive that it has a couple of weak spots. At f/1.4, you have to live with reduced contrast and weak corners but the center quality is pretty good. The question may be whether you really require more than a sharp center here because, usually, you will not place your main subject in the image corners anyway. That being said - it is a limiting factor for astrophotography, for instance. If you want very sharp results across the image field, the Viltrox lens can provide this when stopping down to f/4. Lateral CAs could be a little better at f/1.4 and f/2 but you can, once again, tame them by stopping down a bit (or use CA correct in your favorite RAW converter). Image distortions are very low and that's without any digital trickery. The vignetting characteristic is typical for such a high-speed lens thus there's some visible light falloff at large-aperture settings. The bokeh has its ups and downs depending on the scene. Out-of-focus highlights are nicely rendered. The blur near the image center is very smooth but harsh contrasts in the image corners can be challenging for the lens.

The mechanical quality of the Viltrox AF 23mm f/1.4 XF is surprisingly high. It's tightly assembled and most of the lens is made of metal including the lens hood. You may expect that a lens from a newcomer company struggles in terms of AF but this is not the case really. The focusing speed is very high and AF operations are noiseless - just as they should be. For your peace of mind, it's also good to know that Viltrox keeps on updating the firmware of the lens (currently at v1.0.6).

So all-in-all, the Viltrox lens may not be perfect but if you can live with its limitations, you can get a lot of bang for your bucks here.
