Sigma 15mm f1.4 DG DN Diagonal Fisheye Art
15mm SIGMA Lens | SIGMA Fisheye diagonal
The 15mm SIGMA Lens is a new lens in the Art series that offers a fisheye effect, the main difference between this and other lenses with this effect is that the SIGMA offers excellent sharpness at the entire 180-degree angle of view. The Diagonal Fisheye SIGMA offers an ultra-fast aperture of F1.4 making this an ideal lens for astrography, nature photography and architecture.

Fisheye SIGMA diagonal | SIGMA Fisheye Reserve
- A fisheye in line with the quality standards of the Art range
It is the first diagonal fisheye (covering the entire image) to reach the FMCG market with a brightness of F1.4 for full-frame cameras.
Unlike conventional fisheyes, it is exceptionally sharp across the entire 180-degree viewing angle and offers an ultra-fast aperture of F1.4, making it perfect for a wide range of applications including astrophotography, landscapes, and architecture. The expressive power and characteristic distortion effect of this lens opens up a world of creative possibilities in the field of wide-angle photography.
In terms of optical performance, it offers excellent spot image reproducibility and high resolution by correcting various aberrations, especially sagittal coma flash.
By correcting for sagittal coma flare and other aberrations, this lens can accurately reproduce bright spots of light from corner to corner of the frame even at F1.4, making it ideal for astrophotography.
- Excellent build quality
To support the relatively heavy optical system and improve the robustness and reliability of the
equipment, metal parts are used in key parts. TSC polycarbonate (composite
thermally stable), which has a thermal shrinkage rate equivalent to that of aluminum,
It is optimally used to reduce the weight of the set. Each control element, such as the
rings and switches, it is designed to offer a pleasant touch. SIGMA is proud
the exceptional build quality of its products, which do not compromise durability,
operability and the feeling of owning a unique piece of equipment.
- Top-notch performance and construction
It features an AFL button that can be configured to access a favorite feature via the camera menu. The opening ring has a locking switch and another that allows you to override the click during turning.
Dust and splash resistant structure and water and grease repellent coating. The front optical element features a coating to prevent the adhesion of water and grease to it.
The AF actuator is a high-thrust HLA linear motor with advanced electronic control that allows the focusing lens to be moved with high speed and precision for comfortable shooting.

- Optimized for astrophotography
It offers several functions designed for astrophotography. This brings the total number of wide-angle prime lenses in the Art range for mirrorless cameras with features optimised for this demanding discipline to take on four metres, along with the SIGMA 14mm F1.4 DG DN | Art, 20mm F1.4 DG DN | Art & 24mm F1.4 DG DN | Art.
The switch to lock the manual focus to the desired position prevents an accidental shift in focus when touching the ring. A very useful feature for long exposure photography with fixed focus.
The design of the barrel is optimized for heater use and prevents this accessory from standing out and causing vignetting in the final image.
The bayonet has a standard gelatin filter holder. In addition, the front cover features a locking mechanism and a double compartment to store and protect up to two of these filters.
It features a detachable tripod mount compatible with Arca-Swiss. In the design of the clamp, it has been taken into account that it does not interfere with the eventual use of a heater, something essential in the practice of astrophotography.
- A new addition to the F1.4 line of optics in the Art range carefully optimised for astrophotography
- ■MFL switch (manual focus lock)
Switch to lock manual focus to desired position prevents accidental focus change
when touching the rim. A very useful feature for long exposure photography with fixed focus. - Optimized for the use of a heater
The optimized design of the barrel for the use of heaters (necessary to prevent the production of
condensation inside the optics in natural environments when the temperature drops) prevents
that this accessory stands out and provokes vignetting in the final image. - Rear filter holder
The lens incorporates a standard support for gelatin filters on the bayonet side. - Special front cover with locking mechanism and filter slots
The front lid features a locking mechanism and a double compartment to store up to two
Gelatin filters. Designed specifically for the SIGMA 15mm F1.4 DG DN DIAGONAL FISHEYE | Art,
This cover protects the filters from accidental scratches and dirt build-up, and is also a
An unbeatable way to always carry them with you next to your lens. - Tripod Clamp
The SIGMA 15mm F1.4 DG DN DIAGONAL FISHEYE | Art incorporates a detachable tripod mount
compatible with Arca-Swiss. The lens can be placed on a tripod for stability. In the design
of the clamp has been taken into account that it does not interfere with the possible use of a heater, which is something that
essential in the practice of astrophotography. The TS-141 tripod stand supplied with this
