Mixing advanced optics and sophisticated handling, the Micro Four Thirds-mount MF 14mm f/2.8 WS Mk2 Lens from Samyang is an ultra-wide-angle prime that is especially well-suited to astrophotography, architecture, and landscape shooting applications. Featuring a 14 elements, 10 groups optical design, this lens utilizes a series of aspherical, low dispersion, and high refractive index elements to reduce color fringing, aberrations, and distortions for sharp, clear, and color accurate imagery. An Ultra Multi-Coating is also featured, as well as a built-in petal-shaped lens hood to suppress lens flare and ghosting for improved contrast when working in bright, direct lighting conditions. Complementing the imaging assets, manual focus operation, with an internal focusing design, is employed and permits working with subjects as close as 11" away, and the metal housing is weather-sealed to permit working in inclement conditions. Additionally, a focus lock ring permits securing the focusing position to prevent accidental changes, and the aperture ring can also be de-clicked to better suit video applications.
