Compact and comfortable, the 50mm f/1.8 Lens from Viltrox is a normal length prime lens designed for full-frame-format Sony E-mount mirrorless cameras. The versatile normal field of view is suitable for a broad range of subjects, from portraiture to reportage, and the fast f/1.8 design excels in low-light conditions and for shallow depth of field applications. 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 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. Prime normal-length lens is designed for full-frame format Sony E-mount mirrorless cameras, and when used on APS-C cameras has the equivalent perspective of a 75mm lens Bright f/1.8 maximum aperture suits working in low-light conditions and also affords greater control over depth of field. 11 elements in 10 groups One extra-low dispersion elements and two high transparency elements reduce color fringing and chromatic aberrations in order to achieve a high degree of clarity and color accuracy. Two aspheric elements help to control spherical aberrations and reduce distortion in order to realize high sharpness and accurate rendering. HD Nano multi-layer coating has been applied to individual elements to suppress flare and ghosting for greater contrast and color fidelity when working in strong lighting conditions. STM stepping motor enables quick, quiet, and precise autofocus performance along with full-time manual focus override. The internal focusing design maintains the overall lens length during use for improved handling and quicker response. Integrated manual aperture ring for tactile exposure control; this ring also features an 'A' position for automated, camera-based aperture selection. Integrated micro-USB port for firmware updates.
