An ultra-fast normal-length prime, the XP 50mm f/1.2 from Samyang is a Canon EF-mount lens distinguished by its speed and advanced optical design. Aspherical and high refractive index elements are used to reduce spherical aberrations and distortions in order to realize a high degree of clarity and sharpness, and an Ultra Multi-Coating is also featured to suppress ghosting and flare for increased contrast and color fidelity. It's impressive f/1.2 maximum aperture also benefits working in low-light conditions and affords extensive control over depth of field for working with selective focus techniques. Additionally, the manual focus design contributes to the precise control over focus, and an aluminum-alloy housing benefits handling as well as improves overall durability.
