Sharp Optics, Smooth Performance

Designed to deliver exceptional image clarity and control, the 50mm f/2 DG DN features an optical construction of one SLD element and three aspherical elements that minimize aberrations and distortion. A Super Multi-Layer Coating effectively reduces flare and ghosting for improved contrast and color accuracy, even in challenging lighting conditions.

An internal focusing system driven by a stepping AF motor ensures fast, quiet, and precise autofocus, ideal for both stills and video work. Additionally, a rounded 9-blade diaphragm produces smooth, natural bokeh that enhances selective-focus images.
