Sigma announces 14-24mm F2.8 DG DN Art for full-frame mirrorless
Sigma already offers a well-regarded 14-24mm F2.8 for full-frame DSLRs, and is now adding one to its lineup of lenses for full-frame mirrorless cameras: the 14-24mm F2.8 DG DN Art, to be released in August for Panasonic / Leica L-mount and Sony E-mount.
The company calls it the 'definitive lens for astrophotography' and emphasizes its 'outstanding' resolution to the edges of the frame, achieved in part thanks to the inclusion of low dispersion elements and Sigma's Nano Porous Coating (NPC).
The lens is splash and dustproof, and features a rear filter holder. The aperture diaphragm uses 11 rounded blades, and the lens weighs 28 oz (795g). The expected price is $1499.

Ultimate large-diameter, wide-angle zoom lens optimized for full-frame mirrorless cameras －“The definitive lens for astrophotography” with astonishing resolution.
Many photographers like to use low sensitivity shooting to minimize noise as much as they can. Particularly in the photography of starry skies, bright wide-angle lenses are often selected because they can efficiently collect weak light. The 14-24mm F2.8 DG DN | Art has been developed as the ultimate large-diameter, wide-angle zoom lens by optimizing the standard specifications for photographing starry skies for full-frame mirrorless cameras. The uniform rendering performance and outstanding resolution to the edge of the frame make it the “definitive lens for astrophotography.” By utilizing the characteristics of the short flange focal length, this new-generation large-diameter zoom lens combines both compact body and unprecedented high-resolution image quality.
About Product Name: Product name includes “DG” when the lens is designed to deliver the ultimate in performance on cameras with full-frame sensors, and “DN” when the lens design is optimized for mirrorless cameras with the short flange focal length.
- Newly developed high-performance lens series for full-frame mirrorless cameras With mirrorless cameras emerging at an accelerated pace, expectations towards lenses suited for high-performance full-frame mirrorless cameras are growing. Unfortunately, many photographers may feel that they have little choices for mirrorless lens systems in terms of performance, size, extensive lineup, and due to the burden of having to use multiple systems. SIGMA has thus developed and proposes this new full-frame mirrorless lens series as the optimal solution to this challenge.
SIGMA will develop interchangeable lenses with unprecedented specifications and performance by designs that benefit from the short flange focal length feature of mirrorless cameras while retaining the concepts of “Contemporary,” “Art,” and “Sports.” We will announce three models as the first lenses from this series.
• 45mm F2.8 DG DN | Contemporary
Compact size is realized while maintaining high image quality and is compatible with full-frame mirrorless cameras. This prime lens refines the concept of the Contemporary line.
• 35mm F1.2 DG DN | Art
The world’s first* 35mm F1.2 as L-Mount and Sony E-mount lens for full-frame mirrorless system. The high image quality of the Art line that pursues ultimate performance is realized by F1.2 maximum aperture.
* As an autofocus lens
• 14-24mm F2.8 DG DN | Art
Large-diameter, ultra-wide-angle zoom lens for full-frame mirrorless cameras. While pursuing the ultimate image quality of the Art line, the size is reduced thanks to the exclusive design for mirrorless cameras.
- High-resolution image quality developed with exclusive low dispersion glass elements and NPC (Nano Porous Coating)
One FLD glass and five SLD glass elements are appropriately arranged to suppress chromatic aberration to the edge of the frame. Three aspherical lenses, including a large-diameter aspherical lens at the foremost surface, are used to effectively minimize coma flare, etc., thereby achieving mind-blowing resolution. The super multi-layer coating is combined with a newly developed NPC (Nano Porous Coating)*. The lens has been designed to be less susceptible to strong incident light such as backlight.
* SIGMA’s new unique coating technology "NPC (Nano Porous Coating)" incorporates porous silica as the coating material. The porous silica layer has nano-sized holes with air inside. Having holes of this size enables a large reduction in the refractive index, allowing the reflectance to be lowered more than conventional anti-reflective coatings. As a result, reflected light causing flares and ghosting is sharply reduced, achieving clear image quality.
- Substantial functions enable user confidence, even in tough environments Incorporating a stepping motor enables the high speed, quiet AF drive. Shooting is comfortable even in target AF such as Face/Eye Detection AF and during video shooting. The AFL button which can be assigned with various functions widens the range of operations available on the lens. Furthermore, the lens features a dust- and splash-proof structure, along with a water- and oil-repellent coating on the frontmost surface of the lens, which further supports shooting in various environments.
- Rear filter holder as a standard accessory The lens comes with a rear filter holder equipped with a fall prevention lock for attaching sheet type rear filters for shooting starry skies.
- Full-time manual mode
- Available Mount Conversion Service
- Designed to minimize flare and ghosting
- Evaluation with SIGMA’s own MTF measuring system: A1
- 11-blade rounded diaphragm
- High-precision, rugged brass bayonet mount
- “Made in Japan” craftsmanship

Canon's mirrorless EOS R5 comes with a ton of features and capability stemming from its design inside and out. Come along with us on a guided tour of Canon's new high-end, high-megapixel camera and check it out for yourself.
Announced alongside the EOS R5, the R6 offers a lot of the same technology but in a more affordable, slightly more enthusiast-focused model. Take a closer look.
Alongside the EOS R5 and R6, Canon has announced a brace of lenses, all in the short to long telephoto range. Filling out the 'long' end are one L-series zoom, and two innovative primes.
Alongside a trio of telephoto lenses, Canon also announced a new 85mm this week. The RF 85mm F2 Macro IS STM is a compact, affordable alternative to the pro-oriented 85mm F1.2L.
The EOS R5 has been a long time coming – we knew it had 8K and we knew it had an AF joystick. But now that's it's here, what is it really like to use? Find out in our initial review based on hands-on time with the camera.
The R6 doesn't promise quite such headline-grabbing specs as its big brother, but it still packs a punch, whether you shoot stills, video or both.
Think you've read everything there is to know about the new Canon cameras? Chris and Jordan share eight important things you may have missed from today's Canon EOS R5 and R6 announcements.
We've been shooting around with the new Canon EOS R6. Initial impressions of image quality are positive, and out-of-camera JPEGs appear similar to that of the gold award-winning Canon EOS-1D X III. Have a look for yourself.
Canon has officially released the long-awaited EOS R5, the company's top-end full-frame mirrorless camera. Featuring a new 45MP CMOS sensor, Dual Pixel AF II system, 8K video capture and 20 fps bursts, this is the RF-mount camera we've been waiting for.
Although the Canon EOS R6 doesn't have the 45MP sensor and 8K video capture of the higher-end R5, it's still an incredibly capable camera with specs that outshine similarly priced peers.
The Canon RF 100-500mm F4.5-7.1L IS USM is the company's first super-zoom lens for RF-mount. Despite a relatively slow aperture range, it's very versatile, offering five stops of stabilization, weather-sealing and compatibility with Canon's new teleconverters.
Canon's RF 85mm F2 Macro IS STM is an inexpensive telephoto prime lens with a minimum focus distance of just 0.35m (14") and a 0.5x magnification. When attached to the new R5 and R6, it offers a whopping eight stops of shake reduction.
Canon has announced a pair of super-telephoto fixed-aperture primes. The 600mm and 800mm use diffractive optics to keep their size and weight down. They'll also be compatible with new 1.4x and 2x RF teleconverters.
Canon has announced a new small-footprint inkjet photo printer, the imageProGraf Pro-300. it will produce prints up to 13 x 19" and it goes on sale later this month for $900. A new textured photo paper will also arrive in July.
The new compression standard is set to reduce video file sizes by half to save space and speed-up transmission, paving the way for more portable 8K footage.
Sony recently confirmed plans to launch a successor to the video-centric a7S II. We don't even know the name of the camera, but Jordan already has a feature wish list for the new 'a7S III' – and it doesn't include 8K.
The Profot B10 is the first studio flash system that can be used when shooting with an iPhone camera.
The Pixii camera is an interesting little rangefinder camera that features a 12MP APS-C sensor and lacks a rear LCD display, opting instead to pair with your mobile device, which can be used to view and transfer images.
Sirui is launching an Indiegogo campaign for a wide-angle answer to its existing 50mm F1.8 anamorphic lens. The 35mm APS-C lens will come in a Micro Four Thirds mount with adapters for other systems.
Sony has added a 12-24mm F2.8 to its top-shelf 'G Master' series of lenses. It's the widest constant F2.8 zoom currently offered for full-frame, with a hefty price tag to match: it will sell for $3000 when it ships in mid-August.
Take a look at the view from Sony's new ultra-wide F2.8 zoom – we paired it with the a7R IV for some initial shooting.
