The Sigma 14mm F1.4 DG DN | Art offers an astounding combination of ultra-wide focal length and ultra-large maximum aperture, born from their engineers’ passion for capturing the widest, brightest, highest-resolution, and most captivating starry sky possible. With an ultra-wide angle of 14mm and a maximum aperture of F1.4, this lens has achieved high optical performance with thorough correction of sagittal coma flare, specialized functions to support starry landscape photography, and high-speed AF with HLA (High-response Linear Actuator) linear motor. The 14mm F1.4 DG DN | Art will provide new possibilities for visual expression and enjoyment in all scenes, including daytime landscapes, architecture, and indoor photography in dark and confined spaces.
Ultra wide-angle 14mm with a maximum aperture of F1.4 and outstanding optical performance
This world-first performance was achieved by applying the best of SIGMA’s optical technologies, from the design to the lens manufacturing process. 19 elements in 15 groups, including 1 SLD glass element, 3 FLD glass elements, and 4 aspherical lens elements, make up a luxurious lens configuration. This allows for advanced aberration correction and a high degree of precision in the lens construction. This allows both advanced aberration correction and F1.4 brightness. In particular, sagittal coma flare, which distorts the shape of stars, has been carefully corrected, and even at the widest aperture, the lens delivers high image reproducibility right to the periphery of the image. Ghosting and flare are also thoroughly addressed through both optical design and coatings. This allows for clear, crisp shooting of starry sky and night scenes. Optimized for starscapes, which require extremely high performance, this lens delivers images that exceed expectations in any scene, including landscapes, architecture snapshots, portraits, and indoor photography.
Abundant functions and accessories to support starscape photography
The 14mm F1.4 DG DN | Art is equipped with a wealth of features to support starscape photography. This fully backs up the fun of starscape photography. It includes a detachable tripod mount compatible with Arca-Swiss type. The 14mm F1.4 DG DN | Art can be mounted on a tripod in a more stable condition, as it is heavier on the front side. The shape is designed to prevent interference even when using the lens heater. There is a switch to lock the manual focus at a desired position. This prevents focus shift caused by unintentional operation of the focus ring which is useful for long exposure photography, etc., where the focus is fixed. Steps around the front and a lens heater retainer prevent a lens heater from protruding into
the front of the lens and causing vignetting on the periphery of the screen.The heater prevents condensation from forming inside the lens when the temperature drops. A rear filter holder is provided as standard equipment at the lens mount for attaching a sheet-type rear filter. A lock mechanism is also provided to prevent the filter from falling out. Includes a cover-type front cap with locking mechanism. It also has a newly developed filter slot that can hold two rear filters depending on the application. The cap is specially designed for the 14mm F1.4 DG DN | Art to protect the sheet filters from, scratches and dirt while ensuring that they are not mistakenly taken out or forgotten.
Signature Art line features and high build quality
In addition to functions specifically designed for shooting starscapes, the lens is equipped with various functions to assist in shooting, including an AFL button to which any function can be assigned and an aperture ring. The body is dust and splash resistant, and the frontmost surface of the lens is coated with a water- and stain-repellent coating, so you can shoot outdoors in harsh environments with peace of mind. The HLA (High-response Linear Actuator) enables high-speed, quiet, and highly accurate autofocusing. In order to maintain performance while supporting a lens with a large aperture, the lens has a robust internal structure and uses lightweight materials such as polycarbonate TSC (Thermally Stable Composite), which has a thermal shrinkage rate equivalent to that of aluminum, and magnesium in appropriate locations to reduce weight while ensuring robustness. The lens body is built with the high build quality of the Art line specifications, allowing the user to fully enjoy the unique performance of the lens in any environment, including shooting starscapes.
