The high-intensity standard lens SIGMA 30mm F1.4 DC DN Contemporary lets users of mirrorless cameras experience the fun of shooting with a maximum F1.4 aperture. Particularly attractive are the beautiful Bokeh, which can only be achieved with a fast lens, and the exceptionally precise optical performance, which distinguishes a fixed focal length lens of the top class. Our latest technologies and design considerations, which are characteristic of the concept of the Contemporary product line, are well balanced in this new lens. A fixed focal length lens that offers an angle of view similar to that of the human eye with about 50mm and a light intensity of F1.4. The shallow depth of field with the aperture fully open offers photographers ideal conditions for fascinating portraits and still lifes. For landscape shots or snapshots, a smaller aperture with a greater depth of field can be selected. Standard lenses offer many different photographic applications and have therefore 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 with the designation "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 results in 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 optimum performance in conjunction with cameras with a short overlay.
