This is the image of the upcoming Viltrox AF 16mm F1.8 Full-frame Lens for Sony and Nikon Cameras, leaked online.
Recently, Viltrox has been releasing large-aperture prime lenses one after another, giving me the impression that they are gaining momentum. 16mm is a focal length that is often covered by wide-angle zoom, but with the brightness of F1.8, you can get closer and blur the background, so you can create a variety of expressions.
