The latest optical design thoroughly corrects each type of aberration. This diagonal fisheye lens has the unique expressiveness of a fisheye lens and high resolution throughout the entire image from a wide-open aperture. The performance of the lens is guaranteed by a full inspection with Sigma’s proprietary MTF measuring system.
A small step at the front of the lens called a lens heater retainer prevents the lens heater* from protruding over the front element, eliminating the risk of vignetting.
*A belt-shaped heat strip that is wrapped around the lens to prevent condensation from forming inside the lens when the temperature drops.
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, 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.
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.

In developing a fisheye lens featuring an ultra-wide-angle and powerful fisheye distortion, Sigma has achieved a completely new level of artistic potential, combining the world’s first F1.4 aperture for consumer use with outstanding resolving power across the entire image. In terms of optical performance, the Sigma 15mm F1.4 DG DN DIAGONAL FISHEYE | Art has achieved excellent point image reproducibility and high resolution by correcting various aberrations, especially sagittal coma flare. The lens is capable of handling starscape photography, which demands particularly high-quality performance, even when wide-open. Unlike conventional fisheyes, the Sigma 15mm F1.4 DG DN DIAGONAL FISHEYE | Art is exceptionally sharp across its entire 180° angle-of-view and offers an ultra-fast F1.4 aperture, making it perfect for a wide range of applications including astrophotography, landscapes and architecture. The expressive power of this all-new full-frame mirrorless lens opens a wealth of creative possibilities in wide-angle photography.
* As an interchangeable lens for full-frame cameras for consumer use. (As of February 2024 by Sigma）
