Product Description Offering best-in-class optical performance, this lens is designed to minimise aberrations for images virtually free of streaking and warping. SIGMA has a proven reputation for wide-angle lens design and manufacturing. Drawing on this experience and design know-how, refined through development of the SIGMA 35mm F1.4 DG HSM | Art and 50mm F1.4 DG HSM | Art in our Art line, we have successfully minimised sagittal coma flare, chromatic aberration, distortion, and vignetting to achieve exceptional levels of optical performance with almost no aberration or distortion. This lens provides the best possible performance when photographing a variety of subjects from cityscapes, mountain ranges, and the star-filled night sky to indoor photography with low illumination or scenes that require a smooth bokeh effect. Enjoy the astonishing optical performance of the new F1.4 series that has just joined SIGMA's iconic Art line. This lens features minimised aberration achieved through the latest design technology and know-how that has been accumulated by SIGMA in its lens development over many years and offers astonishing rendering performance, even at the edges, with ultra-high resolution. Whilst featuring higher resolution around the focus point, the lens offers a smooth and natural bokeh effect. Both high definition rendering without chromatic aberration and natural bokeh expression are possible, even at maximum aperture. Sagittal coma flare is the aberration in which a point light source appears as a streak instead of a point, and it affects large-diameter lenses in particular. By positioning aspherical lens elements toward the rear of the 24mm F1.4 DG HSM | Art, we have adjusted the angle of incidence of light for optimal power distribution. Even at wide-open aperture, you will enjoy outstanding image quality. Since streaking of point light sources toward the edges of the image is minimized, this lens is a powerful ally in photographing celestial bodies, night time illumination, and more. FLD,SLD and Aspherical lens elements The 24mm F1.4 DG HSM | Art incorporates FLD ("F" Low Dispersion) glass and SLD (Special Low Dispersion) glass elements to minimise chromatic aberration of magnification, which is mainly visible around the edge of the image. The result is high image quality throughout the entire focusing range-sharp and high-contrast image rendering without colour blur. Improving efficiency at large apertures and minimising vignetting, we have designed the lens to secure very good brightness. Even at open aperture, it ensures high-contrast images for indoor photography, astronomical photography, and when photographing blue sky. When photographing with point light sources such as electric lights or reflections on a body of water in the background, the rounded 9-blade diaphragm helps produce an attractive bokeh effect-even at large-aperture settings. HSM (Hyper Sonic Motor) HSM (Hyper Sonic Motor) delivers high AF speed and extremely quiet performance. SIGMA's latest AF algorithm makes possible even smoother automatic focusing. After AF has done its job, fulltime MF (manual focus) allows you to make fine adjustments to focus simply by turning the focus ring. Using the SIGMA USB DOCK (sold separately) allows you to access the MO (manual override) function, which allows you to manually focus at any time during AF by turning the focus ring. TSC (Thermally Stable Composite) Conventionally it is considered essential to leverage the qualities of metal and polycarbonate in camera and lens layout design. A first for the industry, the barrel of the new series of SIGMA lenses features a new TSC (Thermally Stable Composite) that offers minimal thermal shrinkage combined with exceptional hardness. It also offers 25% greater elasticity than polycarbonate. Since its thermal shrinkage is low, TSC matches well with metal parts, further contributing to the high-precision construction of the lens.
