The new F1.4 series expands the SIGMA Art product line. The highest optical performance in its class, perfect for a variety of photographic subjects from cityscapes to starry night skies. SIGMA has a good reputation for wide-angle lens design and manufacturing. Based on this experience and design know-how and refined by the knowledge from the developments of SIGMA 35mm F1.4 DG HSM | Art and SIGMA 50mm F1.4 DG HSM | Art, SIGMA has successfully minimized sagittal coma, chromatic aberration, distortion and vignetting to achieve exceptionally high optical performance with virtually no imaging errors or distortion. This lens offers the best possible performance when shooting a wide range of subjects, from cityscapes, mountain ranges and starry night skies that require high imaging performance, to indoor shots in low light or shots with a soft bokeh. Pure enjoyment is the astonishing visual line of the new "F1,4" series, which is part of the cult product line Art from SIGMA. SIGMA groups all its interchangeable lenses into three product lines; Contemporary, Art and Sports. The Art product line is designed for sophisticated optical performance and high expressiveness and is suitable for special artistic expression. With an amazing imaging performance that meets the highest standards, these lenses, along with landscapes, portraits, still lifes, close-ups and snapshots, are ideal for the kind of photography that awakens the artist in a photographer. The lenses are not only ideal for studio photography, but offer just as much expressiveness for architectural shots, starry skies, underwater shots and many other scenes. By minimizing imaging errors through the use of the latest technologies and the know-how accumulated over many years of lens development, this lens achieves astonishing imaging performance with very high resolution, even at the edges of the image. While the focused subject is displayed with a high resolution, the lens also provides a smooth and natural bokeh. Both high-resolution reproduction without color errors and natural bokeh are possible with open aperture. Ideally, a high-intensity lens already has a high imaging performance over the entire image area with an open aperture. The sagittal coma, for example, in which the rays of a point light source do not meet at one point, but rather generate a tail, is a typical reflex that occurs above all with wide-angle lenses. The SIGMA 24mm F1.4 DG HSM | Art has an optimized power design by positioning aspherical lens elements on the rear side and adjusting the angle of incidence of the light, so that high reproduction performance is guaranteed even with the aperture open. Due to the reduced distortion of point light sources at the image edges, it is perfectly suited for astrophotography and available light.
