USED Sigma 20mm F1.4 DG HSM Art for Nikon F

Product Features

• Employs a large, approximately 59mm diameter, double-sided aspherical lens to achieve a 20mm focal length ultra-wide angle with a maximum aperture of F1.4.
• Aberrations such as distortion and magnification chromatic aberration are corrected to the extreme. Performance is high even at maximum aperture, with consideration given to sagittal coma flare and peripheral light fall-off.
• Utilizes two FLD glass elements and five SLD glass elements to effectively correct chromatic aberration, a common issue with large-diameter ultra-wide angle lenses.
• Suppresses flare and ghosting, achieving high-contrast images even when shooting against the light.
• Distortion is minimal for an ultra-wide angle lens, making it ideal for architectural, landscape, and astrophotography.
• Equipped with HSM (Hyper Sonic Motor) for high-speed and quiet autofocus.
• Firmware updates and focus point adjustment are possible using the separately sold SIGMA USB DOCK.
