SIGMA 30mm F1.4 DC DN For FUJIFILM X-mount. - Brand: SIGMA - Model Name: 30mm F1.4 DC DN - Filter Diameter: 52mm - Lens Type: Prime The box is also included. Photos including sample images will be posted later. Lens protector and other items shown in the photos will also be included. The focus is fast, and it's a really easy-to-use focal length. I even had the Art 30mm F1.4 when I used Nikon. However, recently my child has started running around, and I've found myself wishing for something a little wider!! Of course, taking a step back is enough to fit everything in, but the sense of distance I feel in the photos feels a bit far, and it's become a difficult focal length as they suddenly approach me. After much deliberation, I introduced a 23mm prime lens, and I've only been using that (lol). The perspective effect is more pronounced, but it's fine since my focus is my child. I hope someone will cherish this lens. It's a truly excellent lens.
