Pros:

negligible longitudinal chromatic aberration,
low lateral chromatic aberration,
lack of distinct problems connected to spherical aberration,
practically zero distortion,

Cons:
noticeable coma,
very high vignetting for RAW files.
Small, shapely, weather-resistant, optically good, with interesting optical parameters – can you ask for more? Of course grumblers might carp about high vignetting or coma levels but fighting those aberrations would also mean bigger physical dimensions of the tested lens so removing one of its more important assets. I guess such a price is worth paying in order to enjoy the Fujinon XF 23 mm f/2 R WR as it is. After all the instrument is a joy to use and completely recommendable.

感觉F2的散光的确很厉害。
