A dynamic ultra wide-angle focal length with an especially bright design. the?FE 14mm f/1.8 GM?from?Sony?is a fast. versatile lens well-suited to landscape. nature. architectural. and astrophotography applications. Its extremely wide-but-usable perspective is complemented by the f/1.8 maximum aperture for excellent performance in low-light conditions and increased control over depth of field. The optical design incorporates two extra-low dispersion elements and one super ED element to reduce chromatic aberrations. plus two XA (extreme aspherical) elements that significantly control spherical aberrations for a high degree of image sharpness and clarity. A Nano AR II coating has been applied to limit ghosting and lens flare for increased contrast and color fidelity when working in strong lighting conditions.
