Because of this, even today many photo enthusiasts are still captured by the tradition and charm of this lens. The NOKTON 50mm F1.2 Aspherical E-mount is a newly designed standard lens with today’s technology for specifications that bring out the best in a high-speed standard lens. By using two out of eight elements, each with two aspherical surfaces, it realizes a compact size while having a large aperture. With this lens, you can enjoy comfortable handling well-balanced with camera body and gentle, ample bokeh.
