Introducing the SIGMA 15mm F1.4 DG DN Diagonal Fisheye, the world’s first (1) full-frame F1.4 diagonal fisheye lens. Capture expansive landscape, star-filled skies, creative portraits and architecture with its bright F1.4 aperture and 180° angle-of-view. Get an all-new perspective and let your creativity flow with unique images with exaggerated proportions. The lens features a host of useful features for astrophotographers. Its built-in rear filter holder allows for gel-type ND filters to be inserted, a lens heater retainer that prevents heat strips from slipping over the front of the lens, and a unique manual focus lock switch that disables the focus ring.

Images are sharp across the whole frame thanks to the sophisticated glass elements that effectively reduce sagittal coma flare and other optical aberrations. With its set of professional features including a special locking lens cap with filter holder, tripod socket, weather-resistant construction, customisable AFL buttons (2), HLA motor and aperture ring, the SIGMA 15mm F1.4 DG DN Diagonal Fisheye for L-mount and Sony E-mount one of the most unique lenses in the SIGMA line-up.

A fisheye lens with outstanding optical quality

The Sigma 15mm F1.4 DG DN Diagonal Fisheye has an incredible 180° angle-of-view. By employing the latest manufacturing technologies and testing using SIGMA’s proprietary MTF measuring system, the lens delivers outstanding quality across the whole frame.

High-resolution images even when shooting at F1.4

The lens can precisely reproduce bright points of light across the whole frame, even when shooting wide open at F1.4. It is constructed using 21 glass elements in 15 groups. 4 FLD and 3 SLD low dispersion glass elements effectively reduce sagittal coma flare and other aberrations. This ensures that bright points of light remain pin sharp at all apertures across the entire frame, ideal for astrophotography.

Designed to minimise flare and ghosting

To prevent flare and ghosting the Sigma 15mm F1.4 was designed using state-of-the-art simulation technology. This resulted in a lens that is highly resistant to flare and ghosting, producing clear and sharp images in challenging lighting conditions.

Feature-packed design

The SIGMA 15mm F1.4 DG DN Diagonal Fisheye | Art has a professional feature-set that makes it easier for photographers and film-makers to achieve the best possible results. Built into the barrel is an aperture ring, which can be set to Auto for aperture control on the camera. With a very precise action, the ring can also be de-clicked if preferred, or locked in place so that it’s not accidentally knocked out of the correct setting.

Lens heater retainer

At the front of the barrel is a Lens Heater Retainer. This helps hold a heat strip in place, which is often used by astrophotographers when shooting in cold conditions to prevent condensation build-up on the front element.

Rear filter holder

The lens features a rear filter holder that allows sheet-type filters to be attached. Soft type filters are preferred by astrophotographers as they make stars appear softer, larger and brighter. Other types of sheet-type filter can also be used. A unique front lens cap has been specially designed with these types of filters in mind. Two filter slots are provided to store pre-cut sheet-type filters, allowing them to be carried with the lens at all times. The cap features a secure lock mechanism to prevent it from falling off unintentionally.

MFL lock switch and AFL button

An MFL (manual focus lock) switch can be found on the side of the lens barrel. This allows astrophotographers to completely disable the focus ring, which is useful once the lens has been set to infinity. This means that even if the ring is knocked the focus will not change.

An AFL button is included on the lens barrel, which can be customised depending on the camera and system.

Detachable tripod socket

As this type of ultra-wide-aperture lens is by nature relatively heavy, attaching the camera to a tripod using the camera’s tripod thread can make the set-up front-heavy, putting the thread under stain and making the camera unstable. So, included with this lens is the TS-141 Tripod Socket, which ensures a more balanced set-up closer to the centre of gravity when mounted on a tripod.

Responsive HLA moror

The Sigma 15mm F1.4 DG DN Diagonal Fisheye is fitted with Sigma’s High-response Linear Actuator (HLA) motor, which delivers faster, smoother, quieter and more accurate focusing than a stepping motor. This is only the fourth Sigma lens to be designed with this technology, ensuring very responsive focusing in all shooting situations.

Understanding: Aperture

Aperture is the opening in a camera lens that controls how much light enters the camera. It's measured in f-stops like f/2.8 or f/8. Lower f-stop numbers mean wider openings, letting in more light and creating a shallow depth of field (blurry background). Higher f-stop numbers mean smaller openings, letting in less light and creating a larger depth of field (more of the scene in focus). Aperture also affects the quality of out-of-focus areas in the image (bokeh).

Understanding: Lens Types

Different lenses have different purposes to achieve different styles of images, some popular ones include:
Prime Lens: Fixed focal length, sharp images, great for portraits and dark settings.
Zoom Lens: Variable focal length, versatile for different shots and everyday use..
Wide-Angle Lens: Captures wide scenes like landscapes.
Telephoto Lens: Magnifies distant subjects, ideal for sports & wildlife.
Macro Lens: Perfect for close-up photography of small subjects.
Fisheye Lens: Ultra-wide perspective, creates unique images.

Understanding: Lens Mounts

Different camera brands use different lens mounts, which are like connectors that attach lenses to camera bodies. Each mount is specific to a particular brand and camera series. For example, Canon uses the EF and RF mounts, Nikon uses the F mount, Sony uses the E mount for its mirrorless cameras. These mounts dictate which lenses are compatible with which cameras. Some brands offer adapters to use lenses from other systems, but it's essential to ensure compatibility for proper functionality and autofocus performance.

Understanding: Manual and Autofocus

Manual focus and autofocus are two ways to adjust the sharpness of a camera lens. With manual focus, you turn a ring on the lens to bring the subject into focus yourself, giving you full control over what appears sharp in the image. Autofocus, on the other hand, relies on the camera's built-in technology to automatically adjust the focus for you, usually by detecting contrast or phase differences in the scene. Autofocus can be convenient, especially for fast-moving subjects or when you need to capture a quick shot, whereas manual focus allows for precise adjustments and creative control over the final image.
