This is the 12mm manual lens I use on the FujiFilm X-E3. This is a very wide-angle lens that allows you to capture many objects at once. Yes, it's not the sharpest around the edges, but for the price, it's a great lens for hobbyists like me. The FujiFilm 18mm costs $900, so it was an easy choice for me. I am very happy with this lens. Build quality is good and the lens feels solid. The aperture ring has a slight click, not the smoothest, but not bad either. You don't have to worry about accidentally changing it. The focus ring is smooth, but most of the time I just set it to infinity and shoot. I know I'm not great at photography, but even I can get some good shots with this setting. Worth buying to play.
