It is optically close to perfect, with sharpness being definitely its super-power. In fact, Fujifilm itself said that with this lens they did focus on resolution to make it fit for “future higher resolution cameras” (aka Fujifilm X-H2).
I know, some might say that lenses are more than just sharpness. And I get the point. I mean, I totally love my XF35mmF1.4, which probably isn’t the sharpest Fujinon X mount lens out there, but has an overall vibe in the images that some describe as “magical”, and indeed, it took some of my favorite images ever.
But if what you need is the ultimate sharpness, then look no further, as the Fujinon XF18mmF1.4 might just be what you were looking for.
Hold on a second… there was one thing I wanted to say.
