The optical design includes two aspherical lens elements, ensuring reliable optical performance and a soft bokeh at maximum aperture. The transmission to an optical viewfinder with distance adjustment is guaranteed via a focusing coupling up to a close focusing limit of approximately 70 cm, depending on the camera. Generally, focusing can be achieved down to 50 cm, for example, with cameras that have a live view function. Despite the high light intensity of F 1.2, the lens has a very compact design and weighs only 315 grams, allowing for wonderfully easy handling.
