Quick Overview Combining a wide-angle perspective with a fast maximum aperture, this  Samyang 12mm  12mm f/2.0 AF Lens is designed for APS-C-format FUJIFILM X-mount mirrorless cameras and provides an 18mm focal length perspective equivalent in 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. check our servcies at golu photos
