A bright and versatile ultra-wide prime, the Pentax K-mount 14mm f/2.8 ED AS IF UMC from Samyang features a bright f/2.8 maximum aperture and is well-suited for subjects ranging from landscape to architecture to astrophotography. The optical design incorporates a pair of aspherical elements and three high refractive index (HR) elements, which control spherical aberrations and distortion. Additionally, two extra-low dispersion elements are used to reduce color fringing and chromatic aberration for improved clarity and color accuracy. An Ultra Multi-Coating has also been applied to limit flare and ghosting for improved contrast and color rendering in strong lighting conditions. This manual focus prime has an 11" minimum focusing distance and also features a built-in petal-shaped lens hood to guard against flare and protect the front element.
