Rokinon IO12AF-E 12mm F2.0 AF Sony E Lens

The Rokinon AF 12mm F2.0 is an ultra-wide-angle prime lens purpose-built for Sony E-mount APS-C mirrorless cameras. With a 99.1° rectilinear field of view, it delivers expansive coverage ideal for landscapes, architecture, interiors, and astrophotography — all while keeping straight lines straight rather than introducing the barrel distortion common in fisheye designs. The fast f/2.0 maximum aperture allows for excellent low-light performance and enables creative shallow depth-of-field effects even at this wide focal length, making it a capable choice for night sky photography where gathering as much light as possible is critical.

Optically, the lens employs 12 elements in 10 groups, including aspherical, extra-low dispersion, and hybrid-aspherical elements that work together to minimize chromatic aberration, distortion, and flare. Tiffen's Ultra Multi-Coating further enhances contrast and color fidelity by reducing ghosting. The autofocus system uses a Linear Stepping Motor for fast, precise, and near-silent focusing — a key advantage for video shooters. Despite its advanced optics, the lens weighs just 7.51 ounces thanks to its compact all-metal construction, and weather sealing with rear protective glass provides confidence when shooting in unpredictable outdoor conditions.
