Sigma 15mm f/1.4 DG DN Diagonal Fisheye Art Lens for Sony E in More Detail

Outstanding optical quality fisheye lens

The 15mm F1.4 DG DN Diagonal Fisheye lens boasts an exceptionally wide 180° angle-of-view, combined with superior optical quality. Utilising advanced manufacturing technologies and rigorously tested with SIGMA's own MTF measuring system, this lens for Sony cameras ensures outstanding quality throughout the entire frame.

High resolution wide open at f/1.4

Even when shooting wide open at f/1.4, the lens is capable of delivering high-resolution images with precise reproduction of bright light points across the entire frame. Its construction includes 21 glass elements in 15 groups, with 4 FLD and 3 SLD low dispersion elements effectively minimising sagittal coma flare and other aberrations. This meticulous optical design ensures that bright light points remain sharply defined at all apertures, making it perfect for astrophotography.


Feature-packed design

The Sigma 15mm f/1.4 DG DN Diagonal Fisheye | Art lens includes professional features, which cater to both photographers and filmmakers. It includes an aperture ring on the barrel, with the option for automatic aperture control via the camera. The ring, characterised by its precise action, can also be de-clicked for smooth adjustments or locked to prevent accidental changes, ensuring the correct setting is maintained in any situation, day or night.

Reduced flare and ghosting

The 15mm f/1.4 lens is engineered by Sigma with advanced simulation technology to minimise flare and ghosting. This design approach has produced an ultra wide angle lens that excels in resisting these effects, ensuring clear and sharp images even in demanding backlit conditions.

Sigma’s proprietary Super Multi-Layer Coating has been applied to help reduce the effects of flare and ghosting, and the front element incorporates a water and oil repellant coating for easier cleaning and maintenance.


Rear gel filter holder

This lens is equipped with a rear filter holder, which allows for sheet-type filters to be attached. Astrophotographers often favour soft type filters, which render stars softer, larger, and brighter, though other sheet-type filters. A specially designed front lens cap accommodates these filters, featuring two slots for storing pre-cut sheets, allowing easy and constant access. Additionally, the cap is designed with a secure lock mechanism to ensure it stays firmly in place and doesn't fall off accidentally while transporting the lens.

Lens heater retainer

At the front of the barrel is a Lens Heater Retainer, which helps to secure a heat strip, commonly used by astrophotographers in cold conditions to prevent the buildup of condensation on the lens's front element.

Manual focus lock switch and AFL button

An MFL (Manual Focus Lock) switch is featured on the side of the barrel, which is particularly beneficial for astrophotographers. Once the lens is set to infinity, this switch can be used to disable the focus ring completely, ensuring any accidental knocks don't alter the focus. Additionally, an AFL (Auto Focus Lock) button is incorporated into the barrel, which can be customised according to the camera and your personal preferences.

Detachable tripod socket 

To address the front heavy design, which is common with ultra wide angle lenses, the Sigma 15mm f/1.4 DG DN Diagonal Fisheye Art Lens comes with the TS-141 Tripod Socket. This accessory helps achieve a more balanced setup by aligning the mount closer to the lens's centre of gravity when attached to a tripod.


Sample image 02 with Leica SL2. Camera settings: Exposure 1/2000 sec. f/4.0. ISO 1600

Responsive high speed focus motor

With Sigma's High-response Linear Actuator (HLA) motor the lens achieves faster, smoother, quieter, and more precise focusing compared to a stepping motor. It's only the fourth Sigma lens to incorporate this cutting-edge HLA technology, providing exceptionally responsive focusing in various shooting scenarios.

Along with high-speed autofocus compatibility, the lens supports AF assist (Sony only), DMF and AF+MF, as well as featuring an inner focus system.


Expansive range of ultra wide angle Art Series lenses

The 15mm Fisheye joins a growing selection of ultra wide angle lenses for creative Sony image makers. These include the Sigma 14mm F/1.4 DG DN Art Lens For Sony E, 20mm F/1.4 DG DN Art for Sony and 24mm F/1.4 DG DN Art for Sony, all of which employ special features for astrophotography.
