This 12mm f/2.0 AF Lens from Samyang is designed for APS-C-format FUJIFILM X-mount mirrorless cameras and provides an 18mm focal length perspective equivalent to 35mm full-frame format. Three extra-low dispersion elements, one aspherical element, and one hybrid-aspherical element are incorporated into the lens construction to help to control aberrations and distortions for increased clarity and sharpness. Ultra Multi-Coating has also been applied to all lens elements to reduce lens flare and ghosting for increased contrast and color fidelity. The bright f/2.0 maximum aperture excels in difficult lighting conditions and enables greater control over depth of field and focus placement. The Linear STM autofocus motor provides fast, quiet focus, and the lens barrel incorporates a custom function switch and a focus hold button for optimal focus control. Additionally, the lens incorporates a seven-blade diaphragm to produce a smooth quality of bokeh.
