Just Announced: Sigma 14mm f/1.4 DG DN Art Lens

Fullframe E-mount lens announcements keep coming with this massive two-and-a-half-pound piece of ultra-wide glass from Sigma.
Sigma 14mm f/1.4 DG DN Art Lens ($1,599) is a ultra-wide-angle full-frame E-mount prime designed for astrophotography, architecture and landscape photography, providing outstanding optical performance for high-end creative and artistic applications.

Specifically designed for astrophotography, this 14mm f/1.4 lens provides a vast 114° angle of view on full-frame cameras. The lens is also compatible with APS-C models where it produces a full-frame equivalent focal length of 21mm.

Optimized for nighttime shooting, the lens includes a tripod socket, manual focus lock switch, lens heater retainer, rear filter holder and filter slots to assist in astrophotography applications.

Optical design features 1 SLD (Special Low Distortion), 3 FLD (Low Dispersion), and 3 aspherical elements combine to achieve outstanding sharpness, while also eliminating sagital coma flare, which distorts the shapes of stars. Super multicoating minimizes ghosting and flare when shooting starry skies and long exposure night scenes.

Equipped with an HLA (High-Response Linear Actuator) autofocus motor, the lens provides fast, quiet, and highly-accurate focusing. A dedicated aperture switch enables clicked and de-clicked operation.

The lens is constructed using a Thermally Stable Composite (TSC) material, along with traditional metals for use in a wide temperature range.
