The Canon EF-Mount 14mm f/2.8 ED AS IF UMC from Samyang is a bright and versatile ultra-wide prime lens with a maximum aperture of f/2.8. It is well-suited for subjects ranging from landscapes to architecture and astrophotography. The optical design includes a pair of aspherical elements and three high-refractive index (HR) elements that control spherical aberrations and distortions. Additionally, two extra-low dispersion elements are used to reduce chromatic aberration and color fringing while enhancing clarity and color accuracy. An ultra-multicoating has also been applied to limit stray light and ghosting, improving contrast and color reproduction in challenging lighting conditions. This manual focus lens has a minimum focusing distance of 11 inches and features a built-in petal-shaped lens hood to protect against glare and safeguard the front element.
