The Sigma 14mm f1.8 DG HSM Art Lens for Nikon F is the world’s first f1.8 ultra-wide-angle full frame lens. The lens is completely unique as it provides a super-fast maximum aperture of f/1.8, a feature that is usually not found on wide angle lenses, but usually on standard and telephoto lenses. This makes the lens capable of capturing truly unique ultra wide angle scenes with insanely shallow depth of field, or a low-light buster; all thanks to its ultra-wide angle/field of view and super-fast max aperture of f/1.8.
The Sigma 14mm f1.8 DG HSM Art Lens for Nikon F provides a regular, superwide view (non-fisheye) and controls distortion through one large aspherical front element, and three smaller aspherical elements. Also found in the lens are several FLD and SLD glass elements; these elements are used to reduce chromatic aberrations and improve image quality.
Prime wide-angle lens is designed for FX-format Nikon F-mount DSLRs, however it can also be used on DX models where it will provide a 21mm equivalent focal length.
Sigma 14mm f1.8 DG HSM Art Lens for Nikon F Features:
As part of the Art line within Sigma’s Global Vision series, this lens is designed to achieve truly notable optical performance and is ideally suited for creative and artistic applications.
Ultra-Wide Angle Shooting
The 14mm focal length of the sigma allows the composition of unique wide angle images that can combine many photographic elements in the same frame. It is perfectly suited for landscape, street photography and photo journalism shooting styles and can create some eye-catching creative shots.
Bright f/1.8 Aperture
The Sigma lens is the world first 14mm design with the uniquely fast aperture of f/1.8, perfect for shooting with quick shutter speeds and in darker light conditions. The combination of bright aperture with ultra-wide perspective make the lens well suited for shooting in low light situations like astro or nightscape photography.
Fast HSM Autofocus System
Using a large hypersonic motor (HSM) that drives the focus elements inside the lens, allows the sigma 14mm to deliver accurate autofocus performance with enhanced speed and smooth operation. The updated autofocus algorithm ensures the optimal focusing abilities of the lens while a full-time manual override allows the lens to be easily manually adjusted by simply turning the focus ring.
High End Optical Performance
Professional shooters demand the best optical quality from their gear and the construction of the 14mm f/1.8 lens delivers, with 16 high end elements arranged in 11 groups for outstanding image quality and edge-to-edge sharpness. The lens uses three FLD (“F” Low Dispersion) elements and four SLD (Super Low Dispersion) elements which dramatically reduce chromatic aberrations that traditionally occur when shooting super-wide angle lenses.
80mm Aspherical Front Element
The front element of the ultra-wide angle is a massive 80mm precision moulded aspherical element, similar to the Sigma 12-24 f/4 lens, that minimises both barrel and pin cushion distortion for incredible straight vertical lines.
Stunning 9-Bladed Circular Aperture
The 9 bladed f/1.8 aperture capability of the lens allows you to incorporate incredibly shallow depth of field into your compositions, so you can easily separate your subject from the background. The circular aperture design of the 9 aperture blades creates a beautiful bokeh rendition in out-of-focus parts of your shot.
Super Multi-Layer Lens Coating
By utilising an advanced coating on the lens elements sigma have managed to significantly reduce flaring and image ghosting with the lens. Designed to assist when shooting in backlit shooting situations the lens coating works together with the tried and tested optical design to produce sharp high-contrast images in the most demanding situations.
Solid Durable Construction
The lens has been manufactured from a thermally stable composite material, and features a rugged brass bayonet mount for improved strength. A dust a splash-proof construction around the lens mount gives you the confidence to shoot in a range of conditions and a water and oil repellent coating helps protect the front element.
Nikon Mount Supports Electromagnetic Diaphragm
The Nikon mount version of the lens includes an electromagnetic diaphragm mechanism so it can take advantage of precision diaphragm control and better auto exposure performance with newer Nikon camera models.
Compatible with Sigma Accessories and Adapters
The Sigma 14 mm f/1.8 DG HSM Art Lens supports customisation and fine adjustments with the Sigma USB dock and can be modified with the Sigma Optimisation Pro software.
