High optical performanceExceptionally well-corrected chromatic aberration and sagittal coma flareThrough the use of Sld glass, high refractive index glass with high anomalous dispersion characteristics, and four glass-molded double-sided aspheric lenses, this lens achieves correction of axial chromatic aberration and sagittal coma flare, resulting in both a significant size reduction and enhanced optical performance.Compared to the previous model, the Sigma 35mm F1.2 Dg Dn | Art, which has an established reputation for performance, the new lens offers improved performance across a wider area from the center of the image, allowing photographers to make full use of its F1.2 maximum aperture.Beautiful bokehThorough correction of axial chromatic aberration and sagittal coma flare contributes not only to the sharpness of the image plane but also to the bokeh effect.
