Look, I can't afford the XF23mm 1.4. I just can not. And the XF23mm f2 is quite soft in my opinion and has disappointed me many times. So when I heard that Viltrox was getting great reviews, I took it for myself. For my shooting style, it's fantastic on so many levels. Does it have problems with CA and vignetting? Yes. Is it easy to fix? Yes. Do you even have to fix them? No, vignetting is actually pretty typical for me. This lens has character. As many say, the XF35mm f1.4 has "character” and "magic”. This is an excellent lens. The best? $329 is crazy for this lens. What value. It is now firmly attached to my X-T3.
