Sony E Mount FE 50mm F1.8 Full-Frame Lens (SEL50F18F)

• One aspherical element is incorporated in the lens design to reduce astigmatism, field curvature, coma, and other monochromatic aberrations.
• Double-gauss optical configuration helps to reduce field curvature and distortions for more consistent image quality from edge-to-edge.
• Besides contributing to depth of field control and low-light performance, the bright f/1.8 design also helps to achieve a lightweight and compact profile, making this lens suitable for everyday, walkaround shooting.
• Rounded seven-blade diaphragm contributes to a pleasing bokeh quality when employing selective focus techniques.
