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.
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.
Includes a detachable tripod socket compatible with Arca-Swiss type. As the 14mm F1.4 DG DN | Art is heavier on the front side, attaching the tripod socket helps it mount on a tripod in a more stable way. The shape is designed to prevent interference even when using the lens heater.
When the MFL switch is set to “LOCK”, the focus ring operation will be disabled. It prevents focus shift caused by unintentional operation of the focus ring. This is useful for long time exposure photography, etc., where the focus should be fixed.
A lip at the front of the lens prevents the lens heater* from protruding into the front of the lens and causing vignetting on the periphery of the screen.
*A belt-shaped heater that is wrapped around the lens to prevent condensation from forming inside the lens when the temperature drops.
*Lens heater is not included.
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 newly developed filter slots 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.
