Fast autofocus 12mm f/2 ultra-wide for Fujifilm X mount — ideal for astrophotography.
The Samyang AF 12mm f/2 X is a fast ultra-wide autofocus prime for Fujifilm X mount APS-C cameras, providing an 18mm equivalent view with a fast f/2 aperture. The autofocus capability at this ultra-wide focal length distinguishes it from the popular manual-focus Samyang 12mm, adding significant practical convenience.
Optical quality is good with sharp performance and the fast f/2 aperture making it particularly suited to astrophotography where both wide angle and fast light gathering are essential. The lens handles the challenges of an ultra-wide APS-C design competently with reasonable distortion and flare control.
Build quality is solid with a compact metal barrel suited to Fujifilm's small camera bodies. The autofocus motor provides adequate speed for the ultra-wide focal length where depth of field is naturally generous. Electronic contacts enable full communication with Fujifilm bodies for EXIF and AF operation.
On the used market, the Samyang AF 12mm f/2 X offers the most affordable ultra-wide autofocus option for Fujifilm. For astrophotographers, landscape shooters, and Fuji users wanting dramatic wide-angle perspectives with AF convenience, it provides compelling capability at a budget-friendly price.
