Review Lens: Yongnuo EF 50mm F1.4

Lens Overview - Yongnuo EF 50mm F1.4

A bright normal-length lens, the Canon EF-mount YN 50mm f/1.4 from Yongnuo is a versatile prime well-suited for available-light photography in a variety of situations. The fast f/1.4 maximum aperture offers increased control over depth of field for working with shallow depth of field techniques and also suits working in difficult lighting conditions. The optical design incorporates four ultra-high refractive index elements, which reduce spherical aberrations and distortion, and individual elements feature a multi-layer coating to suppress flare and ghosting for improved contrast and color accuracy when working in strong lighting conditions. A DC motor affords quick and accurate autofocus performance and a switch lets you quickly change from AF and MF focusing methods. Additionally, a micro-USB port is integrated in the lens design to permit installing firmware updates.

Normal prime is designed for full-frame Canon EF-mount DSLRs, however can also be used with APS-C models where it provides an 80mm equivalent focal length.
Fast f/1.4 maximum aperture affords a great deal of control over depth of field for isolating subjects and using selective focus, and also benefits working in low-light conditions.
