Samyang AF 12mm f/2 X - Fujifilm X-mount

Designed specifically for Fujifilm X-mount APS-C cameras, this ultra-wide 12mm lens provides an 18mm equivalent focal length. It features a fast f/2.0 maximum aperture, making it a popular choice for astrophotography and interior shooting. The lens is weather-sealed and incorporates a linear STM motor for fast, quiet autofocus, housed within a compact, lightweight barrel that complements Fuji's X-series aesthetic. Verify the condition of the rear weather-sealing gasket and the responsiveness of the autofocus motor. The front element is quite large relative to the barrel, so check for cleaning marks or scratches. SDS tests the lens for decentering, a common issue in wide-angle primes, and confirms the electronic communication between the lens and Fuji bodies is consistent and reliable.
