Samyang 12mm F/2 NCS CS Lens for Fujifilm X-Mount - Silver
It is a extra-wide-angle manual focus lens designed for APS-C crop sensor mirrorless cameras. With low distortion and wide angle, photographers who want wide-angle photos such as landscape and architectural images can create satisfactory images. F2.0 is very bright so it captures clear and vivid images even under relatively dark environment.
