AF 33mm f/1.4 E from Viltrox is a normal-length prime lens designed for Sony E-mount mirrorless cameras. The versatile normal field of view is suitable for a wide range of subjects, from portraiture to reportage, and the fast f/1.4 design excels in low-light conditions and for shallow depth of field applications. The optical design incorporates extra-low dispersion and high refractive index elements to suppress a variety of aberrations and distortion and an HD Nano multi-layer coating has also been applied to reduce flare and ghosting for greater contrast in bright and backlit conditions.
Complementing the optics, the lens’s design also incorporates an STM stepping motor that affords fast, near-silent, and accurate autofocus performance along with full-time manual focus override. An internal focusing design also contributes to quick performance. Additionally, the lens features an integrated micro-USB port for making future firmware updates to the lens.
