Viltrox 50mm f/1.8 Lens for Sony E-Mount

By B&H Photo’sVal LazarevThe 50mm f/1.8 Lens for Sony E-Mount from Viltrox is a full-frame format lens with a versatile normal field of view suitable for a broad range of applications, from portraiture to reportage, and the fast f/1.8 design excels in low-light conditions and for shallow depth of field. The optical design incorporates one extra-low dispersion, two high transparent, and two aspheric elements to suppress a variety of aberrations and distortion, and an HD Nano multilayer 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.
