Sigma just announced their groundbreaking new 14mm f/1.8 DG HSM lens, the “seventh of their full frame prime lenses to join the Art line.” This ultra-wide-angle lens features 9 aperture blades, a ring-type ultrasonic (HSM) focus motor, a minimum focusing distance of 27cm and 16 elements. Three of the 16 elements are low dispersion (FLD) and another 4 super-low dispersion (SLD).

- 14mm ultra-wide-angle view and f/1.8 brightness that delivers a new dimension of visual experience
- Minimised chromatic aberrations
- Large-diameter aspherical lens element
- Minimised distortion
- Distinctive bokeh effect
- High-precision, durable brass bayonet mount
- Designed to minimise flare and ghosting
- Fast AF with full-time manual override
Press Release
SIGMA 14mm f/1.8 DG HSM
Introducing the world’s first and only* f/1.8 ultra-wide-angle lens
A true high-speed lens that delivers a new dimension of visual experience
*Among interchangeable lens for DSLRs as of February 2017.
Key features
- 14mm ultra-wide angle of view and F1.8 brightness deliver a new dimension of visual experience
By leveraging its extreme angle of view and the dramatic perspective this creates, an ultra-wide-angle lens can get up close and personal with a subject while at the same time taking in a vast background — an example of photography going beyond normal human vision.
SIGMA 14mm f/1.8 DG HSM Art combines the extremely deep depth of field that comes from an ultra-wide angle of view with the extremely shallow depth of field that comes from f/1.8 brightness. The result is a sharply captured subject set against a vast background dramatically blurred with a beautiful bokeh effect. It is a highly impressive mode of photographic expression that until now simply has not existed.
- Minimised chromatic aberrations
Three FLD glass elements and four SLD glass elements help minimise transverse chromatic aberration, which tends to be noticeable in shots taken with ultra-wide-angle lenses. The result is outstanding image quality from the centre of the image to the edges.
- Featuring a large-diameter aspherical lens element
The SIGMA 12-24mm f/4 DG HSM Art was the first SIGMA lens to feature a large ⌀80mm aspherical lens element. Building on the expertise derived from this success, the new lens features a large ⌀80mm precision-molded glass aspherical lens as its front element. This technology has made possible the 14mm f/1.8 specification—the first of its kind.
- Minimised distortion
Serving as the front lens element, the large ⌀80mm precision-molded glass aspherical lens effectively minimises distortion. Offering excellent peripheral brightness, this lens delivers outstanding image quality from the center to the edges.
- Distinctive bokeh effect
Even at the 14mm ultra-wide-angle of view, f/1.8 brightness makes possible a very shallow depth of field with the subject standing out dramatically against a bokeh background. It’s the unique mode of expression that only a large-diameter lens can deliver.
2. Seventh 35mm full-frame prime lens to join the Art line
Launched in 2012, the SIGMA 35mm f/1.4 DG HSM Art was the first lens in the Art line. Since then, SIGMA has developed a wide variety of lenses for the line, and the SIGMA 14mm f/1.8 DG HSM Art is the seventh prime lens in the line to offer 35mm full-frame coverage. Now even stronger, the Art line sets the new standard for prime lenses in the ultra-high-megapixel era.
3. Other features
A true high-speed lens that delivers a new dimension of visual experience
In taking photographs of starry skies or other celestial scenes at night, or of the seashore with a wide perspective, a large-diameter lens is a strong ally, since it allows the capture of a moving subject by adjusting shutter speed without relying on ISO sensitivity. With its full-frame 35mm coverage, 14mm focal length for an ultra-wide angle of view, f/2 barrier-breaking f/1.8, the SIGMA 14mm f/1.8 DG HSM Art is the true high-speed ultra-wide-angle lens for which so many photographers have been waiting. Although some zoom lenses are available that can cover 14mm, the large diameter delivering f/1.8 brightness is a singular advantage. Going beyond fast shutter speed, this lens can capture a swarm of fireflies with crystal clarity, a beautiful bokeh effect, and outstanding control of light streaking.
