Description
With a focal length of 20mm and f1.4 aperture, this lens delivers outstanding large-aperture brightness and bokeh, delivering unprecedented visual experiences. To offer an ultra-wide-angle 20mm focal length and f1.4 brightness at wide-open aperture, this lens incorporates a large double aspherical lens 59mm in diameter. This lens minimizes chromatic aberrations, a common issue in large-aperture ultra-wide-angle lenses. It features two FLD (“F” Low Dispersion)* glass and five SLD (Special Low Dispersion) glass elements to minimize transverse chromatic aberration, which is mainly visible around the edge of the image. The optimized lens power distribution helps minimize axial chromatic aberration. As a result, this lens delivers high image quality in every situation without colour smearing, and its rendering performance is consistently sharp with high contrast.
