The powerful standard lens SIGMA 30mm F1.4 DC DN Contemporary gives users of mirrorless cameras the fun of taking photos with a maximum aperture F1.4. The beautiful Bokeh, which can only be achieved with a high-intensity lens, and the extraordinarily precise optical performance that distinguishes a top-of-the-range fixed focal length lens, are particularly attractive. The latest technologies and design considerations, which are characteristic for the concept of the Contemporary product line, are well balanced in this new lens. A fixed focal length lens with a focal length of about 50mm and a luminous intensity of F1.4, which provides an angle of view similar to that of the human eye. The shallow depth of field with a fully opened aperture offers photographers ideal conditions for fascinating portraits and still lifes. For landscape shots or snapshots, a smaller aperture with greater depth of field can be selected. Standard lenses offer a wide range of photographic applications and have been part of the basic equipment of photographers for decades. This standard lens offers a 35mm equivalent focal length of 60mm on the Micro-Four-Thirds system and 45mm on the Sony E-Mount system. Sigma lenses called "DC" offer optimum performance on cameras with APS-C image sensors. Using a DC lens on a camera with a full-frame image sensor inevitably leads to vignetting. For optimum results, the active image field of the sensor must be adapted to the image circle of the lens. SIGMA lenses with the designation "DN" offer optimal performance in combination with cameras with a short contact distance.
