The world’s first and only* lens that combines an ultra-wide angle of 14mm with a maximum aperture of F1.4.
All for the best starscape photography.
The stars in the sky are a source of inspiration for viewers. On the other hand, the starry sky is a very demanding subject for a wide-angle lens, with its numerous tiny point light sources spread over the entire image. The 14mm F1.4 DG | Art is the world’s widest F1.4 single focal length lens*, born from our engineers’ passion for capturing the widest, brightest, highest-resolution, and most captivating starry sky possible. Thanks to Sigma’s latest technology, the lens combines an ultra-wide angle of 14mm with a maximum aperture of F1.4. In addition, Sigma’s lens technology 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 Milky Way stretching across the night sky, twinkling stars emerging over ridgelines―The 14mm F1.4 DG | Art can make this a reality as a pictorial image that surpasses the actual photographic experience. Its proven ability in shooting starscapes 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
Excellent optical performance
Abundant functions and accessories to support starscape photography
The 14mm F1.4 DG | Art is equipped with a wealth of features to support starscape photography. This fully backs up the fun of starscape photography.
Tripod Socket
Includes a detachable tripod socket compatible with Arca-Swiss type. As the 14mm F1.4 DG | 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.
MFL (Manual Focus Lock) Switch
Lens Heater Retainer
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.
Rear filter Holder
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.
Special front cap with locking mechanism and filter slots
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 | Art to protect the sheet filters from scratches and dirt while ensuring that they are not mistakenly taken out or forgotten.

MTF CHART GUIDE
The MTF (Modulation Transfer Function) is one of the measurements for evaluating a lens’ performance, and it shows how faithfully the contrast of the subject can be reproduced on the image plane. The horizontal axis shows the image height (distance from the center of the image in mm) and the vertical axis shows the contrast value (maximum value is 1).
The closer the 10 line pairs/mm curve is to 1, the higher the contrast and clarity of the lens is, and similarly, the closer the 30 line pairs/mm curve is to 1, the better the resolution and sharpness of the lens is.
*The MTF chart depicts the result at the wide-open aperture.
*For mirrorless lenses that support distortion correction, the horizontal axis shows the image height equivalent to when an L-Mount lens is attached to a Sigma L-Mount camera with distortion correction applied. (The effect of distortion correction may differ depending on the mount and camera used.)
*The spatial frequency indicates the variation on the image plane before distortion correction is performed.
To increase stability, this lens configuration uses movable internal lens elements that adjust focus without changing the length of the lens barrel.
HLA is Sigma’s proprietary linear motor. It drives the focus lens directly without going through gears or other mechanical parts, resulting in quiet, high-precision autofocusing.
Matching the optical characteristics of the lens, this function performs in-camera corrections of peripheral illumination, chromatic aberrations, distortion, and more, to further enhance image quality.
*Function available on supported cameras only. Available corrections or auto correction functionality may vary depending on the camera model.
*On cameras where lens aberration correction is controlled with ‘ON’ or ‘OFF’ in the camera menu, please set all aberration correction functions to ‘ON'(AUTO).
Sigma’s own Super Multi-Layer Coating suppresses flare and ghosting by preventing reflections with in the lens. All lenses in the current Sigma range feature this original technology. In digital cameras, flare and ghosting may also be caused by reflections between the image sensor and lens surfaces. Here too, Sigma’s Super Multi-Layer Coating is highly ef fective, assuring images of outstanding contrast.
Incorporates a water and oil-repellent coating that allows water to be wiped away easily and prevents oil and fat from sticking to the surface, even in challenging shooting conditions. At the same time, the maintenance of the lens surface becomes easier.
Aperture ring
Aperture ring, designed to help users work intuitively
Mounted with a de-click function for removing clicks by the aperture ring click switch, enabling seamless operations that are especially useful such as during video shooting.
Aperture ring
Aperture ring, designed to help users work intuitively
A ring lock system to prevent from unintended movement of the aperture ring during shooting.
The AFL button can be assigned with various functions widens the range of operations available on the lens.
The MFL (Manual Focus Lock) switch disengages the focus ring on the lens. After manually focusing the lens to the desired position, set the MFL switch to ‘LOCK’ in order ]to disengage the focus ring.
This prevents the focus of the lens from being moved by accident (such as when attaching a lens heater or changing the composition) and causing out of focus images. The focus ring can still be rotated but will have no effect.
* Please note that some camera bodies may continue to AF even if the MFL switch is set to ‘LOCK’, or allow AF temporarily even when the camera has been set to MF, and shift the focus when the MFL switch is set to ‘LOCK’.
The rear filter holder allows the attachment of a sheet-type filter to the rear part of the lens.
Trace the shape on a sheet filter using the guide plate and cut it out for use.
The Lens Heater Retainer is a protruding lip at the front of the lens. When the lens is used in conjunction with a lens heater, the Lens Heater Retainer stops the heater from over hanging the front element and causing vignetting. Lens heaters prevent condensation and night dew during nightscape photography such as astrophotography.
Using this swich, it is possible to switch the focus mode between AF and MF.
A focus movement method of interchangeable lenses for mirrorless cameras (DN lens) in relation to the rotational angle of the focus ring during manual focusing.
With “non-linear focus,” the amount of focal point movement varies depending on the focus ring rotational speed.
With linear focus, if the focus ring rotational angle is the same, the amount of focal point movement remains the same regardless of the focus ring rotational speed.
This lens features a highly effective dust and splash resistant structure with special sealing at the mount connection, manual focus ring, zoom ring, and cover connection.
*Although this construction allows the lens to be used in light rain, it is not the same as being waterproof, so please prevent large amounts of water from splashing on the lens. It is often impractical to repair the internal mechanism, lens elements and electric components if they are damaged by water.
*The sample images shown here were taken using the 14mm F1.4 DG DN | Art. The optical performance is the same.
