With land buys, Nebraskan has added on-the-ground conservation to Photo Ark’s visual focus

[ad_1]

Joel Sartore celebrated two very visible milestones last month.







magpie

Joel Sartore reached a new milestone in the National Geographic Photo Ark last month, adding his 14,000th species. The Indochinese green magpie, named Jolie, is at the Los Angeles Zoo. She survived being smuggled in a suitcase, with little ability to move, during a flight from Vietnam.




The Lincoln-based National Geographic photographer added his 14,000th species to the National Geographic Photo Ark, a project he founded in 2005 to document Earth’s biodiversity. The stunning Indochinese green magpie named Jolie, now at the Los Angeles Zoo and Botanical Gardens, was one of only eight birds — out of 93 — to survive a flight from Vietnam in a wildlife trafficker’s suitcases in 2017.

Twenty of Sartore’s photos of endangered species from the Photo Ark were featured on a panel of U.S. postage stamps released to commemorate the 50th anniversary of the Endangered Species Act. One, a piping plover, was photographed near Fremont, Nebraska.

But Sartore and his wife, Kathy, also have been quietly working on a less visible conservation project.

Over about the past dozen years, the couple have purchased about 5,700 acres of what Joel Sartore called “conservation land” — pastureland dotted with marshes, lakes and native grasses that are home to thousands of birds in warm months — in southern Sheridan County in Nebraska’s Sandhills.

They partner with a local ranch family with a similar conservation ethos. Jaclyn and Blaine Wilson, the daughter-father pair who operate the nearby Wilson Flying Diamond Ranch, and another family member lease and run cattle on the grazeable acres. The Wilson ranch was awarded Nebraska’s first-ever Leopold Conservation Award by the Sand County Foundation in 2006.







stamps

Twenty of Joel Sartore’s photos of endangered species for the National Geographic Photo Ark were featured in a panel of stamps that the U.S. Postal Service issued last month to mark the 50th anniversary of the Endangered Species Act.




“It’s a lovely place, and it’s something I feel like I can do for conservation in a way that Photo Ark doesn’t do,” Sartore said. “This is real on-the-ground stuff.”

He and his wife, he said, have financed the purchases themselves by working hard and saving their money over the years. Sartore is known for his frugality and hard work; as a youth in Ralston, he worked at gas stations and a record store, mowed lawns and cleaned aquariums. Early in their marriage, he said, the couple bought, fixed up and sold two small farms in the Lincoln area, doing much of the work themselves.

The couple plan to put the land in trust so it’s maintained at its current level of use by people who have been there for generations, Sartore said. They also want to protect its abundant water from people who might come calling from drier regions.

“It’s a lifetime of work, and this is what we ended up with,” he said. “If we can afford it, we’d love to do it again.”

They also have purchased a couple of smaller conservation properties in eastern Nebraska — two small farms, one near Bennet and the other near Ceresco, as well as a pasture near Valparaiso. They’ve implemented conservation measures on all three, instituting rotational grazing on the pasture, as well as restoring ponds and planting native grasses and wildflowers for birds and pollinating insects.

But the bulk of their conservation purchases, he said, have been in Sheridan County. They bought their first pasture in the area in about 2011. They added larger parcels in 2019 and 2022, according to Sheridan County Assessor’s Office records, purchasing a total of about 4,400 acres for approximately $3.56 million.

Sartore said the couple focuses on wet ground — land a rancher can’t make much of a living on but that yields big conservation returns, land that provides habitat for waterfowl and upland ground for long-billed curlews, a species in decline. It’s also less costly acre-for-acre than farmland.

“These are not places you buy if you really want to invest your money,” he said.

Jaclyn Wilson recalls getting an email from Sartore in March 2020, about the time COVID-19 was taking off. Wilson, a fifth-generation rancher, knew who he was. Her grandparents gave her family a National Geographic subscription for Christmas each year. Its arrival in the mail was a monthly highlight.

In his email, Sartore counted himself among Wilson’s biggest fans. She has been writing opinion columns for the Midwest Messenger, an ag-focused publication, for more than a decade.

Wilson invited him to visit the ranch, and Sartore spent several days there in August 2020. He brought a biologist, and they collected insects, identifying 100-some species, including some new to the Photo Ark and a beetle that previously hadn’t been found that far north.

“It was really cool stuff,” Wilson said.

She took him to the property he’d previously purchased, and he asked if there were similar properties available in the area. Sartore’s more recent purchases include Thompson Lake, which is known for waterfowl, and Snow Lake, which features waterfowl and curlews and also is known for salamanders.

Sartore recalled that he’d read a real estate listing about the salamanders, which mentioned them as a commodity that could be seined and sold for fishing bait.

He said Dan Fogell, a herpetologist and life sciences instructor at Southeast Community College in Lincoln, has identified them as a subspecies of the Western tiger salamander called the Gray tiger salamander. They’re usually found a bit farther north, Fogell told him, but they’ve been found in multiple places in the Sandhills as well.







sartore sandhills

Jaclyn Wilson, left, and friend Amy Sandeen watch a thunderstorm roll in from the first pasture that Joel and Kathy Sartore purchased in the Sandhills for conservation more than a decade ago. Wilson, a fifth-generation rancher, operates the nearby Wilson Ranch near Lakeside, Nebraska, with her father, Blaine Wilson. Wilson family members run cattle on the Sartores’ pastures.




Wilson said her grandparents emphasized conservation and passed down those lessons to later generations. They planted thousands of trees and adopted management practices that are now widely recommended. They raised game birds for release to enhance local populations and only cut hay at certain times of the year. The family also has worked to restore a wetland on its property. In recent years, the ranch has begun selling beef direct to consumers through its website.

Both the family and Sartore encourage scientists to study wildlife on their properties. One project, Wilson said, involved collecting sonar data on bat populations. Another researcher studied dung beetles. Sartore noted that the Nebraska Game and Parks Commission bands geese in the area each spring.

“It’s been really neat that we’ve been able to bridge that gap with some of the conservationists he works with,” Wilson said.

Sartore said he likes the Sandhills because it polices itself. Run too many cattle for too long, and it creates bare spots, or blowouts.

He said he doesn’t have to worry about the condition of the land where he has made his purchases. It was, and continues to be, managed by people who care.

But the family’s purchases offer a chance to keep the most beautiful places from being developed after they’re gone, he said. Many of natural areas where he collected tadpoles and crayfish as a kid in Ralston now are under concrete.

Sartore takes other conservation measures, too, including maintaining a pollinator garden at his Lincoln office, complete with signs explaining what it is and how to do it at home. The FAQ section on his website — joelsartore.com — includes tips on how anyone can help save species, from properly insulating their homes to conserve energy to cutting back on single-use plastic items like grocery bags.

“We just think nature needs a break, and it has to be intentional,” he said.

Meanwhile, Sartore, who’s nearing 61, continues what he calls his “day job” with Photo Ark, a job he wants to continue as long as he can. For many species, the photographs are the only vetted and accurate record of their existence. His son, Cole, now accompanies him on overseas shoots.

He said he may hit 15,000 species by the end of the year. Initially, he estimated that the project would come in around 12,000 species, based on the number in the world’s accredited zoos and aquariums at the time. But those have grown in number, and he’ll go anyplace animals are in human care, from fish markets to wildlife rehabilitation facilities. He could see the Ark possibly reaching 20,000 species.

“It’s meant to inspire (people to) want to save nature and save themselves at the same time,” he said.

These 10 No-Filter Photos that Appear to Be Impressionist Paintings Will Make You Rethink Everything You Know About Photography

[ad_1]

The famous French photographer Réhahn’s new series, “Memories of Impressionism,” merges the styles of Impressionist painters with photography to create a whole new art form. By using groundbreaking techniques, such as shooting through heat waves or water, he manages to give the images the appearance of layers of oil paint. All the photos are created with no filters. Just by a man with a camera and his inspiration.

Follow along below to see these mind-bending images and to learn how Réhahn works his artistic magic.

You can find more info about Réhahn:

#1 “Flame”

Memories of Impressionism By Rehahn

Shot through heat waves as this farmer burned her field to renew the soil, the image takes on a smudged quality that mimics layers of glaze and paint.

#2 “Into The Cloud”

Memories of Impressionism By Rehahn

Shot through smoke and heat shimmer, a woman fanning the smoke in her field in Hoi An, Vietnam seems to be emerging from the clouds.

#3 “Luminous”

Memories of Impressionism By Rehahn

Réhahn captured this shot by focusing on a silhouette of a farmer in a flooded ricefield to emphasize the connection between man and nature.

Memories of Impressionism By Rehahn

This photograph by Réhahn truly takes on an Impressionist air with a texture that seems to be applied with a palette knife. In fact, the texture is the scattering of salt across flooded salt fields. Caught in a reflection, the man seems to merge with the sky above.

#5 “Oasis”

Memories of Impressionism By Rehahn

Shot in a reflection on wet sand, the blurred image of a woman walking with her baskets takes on a surreal dreamlike appearance.

#6 “Cloudkeeper”

Memories of Impressionism By Rehahn

This photograph is part of Réhahn’s “Salt” series. He shot the salt farmer in a reflection of a flooded field, allowing the layers of salt in the water to create a cloudlike effect against the reflected blue sky.

#7 “Echo”

Memories of Impressionism By Rehahn

This photograph of a woman tending to her lotus pond is an homage to Monet’s waterlilies and his obsession with photographing them again and again. Réhahn shot the image in the reflection of the pond to create a surreal sanctuary.

#8 “Glorious Ashes”

Memories of Impressionism By Rehahn

Cezanne’s melancholy color palette was the inspiration for this photo of a woman working in a burning field. Shot through heat haze, certain details disappear, like the fact that she was working barefoot in the field with the heat of the flames and the smoke around her.

#9 “Through The Net”

Memories of Impressionism By Rehahn

A mosaic of golden light surrounds this fisherman like a honeycomb. Shot through the web of a yellow fishing net, the image is submerged in color like a glaze.

#10 “Glowing Fields”

Memories of Impressionism By Rehahn

The cycle of death and rebirth inspired this portrait of a woman burning her field to refresh the soil. The color palette recalls antique paintings and the spontaneous brush strokes of Impressionist painters.

Mary Kay strengthens its partnership with the Nature Conservancy

[ad_1]

Mary Kay, the renowned cosmetics company, recently announced the extension of its decades-long partnership with The Nature Conservancy (TNC) to strengthen ocean conservation and coral reef protection.

Deborah Gibbins, chief operations officer at Mary Kay Inc., said in a press release:

Like all rivers and tributaries, most good things in our world lead back to oceans.

Noting that traditional reef conservation strategies have not been enough to counter the global loss of coral reefs, Mary Kay, a signatory to the United Nations Global Compact’s Sustainable Ocean Principles, offers its continued support to Global Oceans programs and TNC’s Super Reefs, which allow researchers to assess reef health, identify potential super reef locations, and discuss opportunities to improve super reef management locally.

Mary Kay supports experts from The Conservancy, Woods Hole Oceanographic Institution (WHOI) and Stanford University as they lead a collaborative effort to unlock the secrets of “super reefs,” a diverse coral community within a reef system that is more resilient or resistant to damaging heat waves, in an effort to predict, test and protect critical coral reefs.

This information will help guide reef conservation and restoration efforts in Hawaii, Palau, Indonesia, the Marshall Islands, the Bahamas, the Dominican Republic, and Belize.

Coral reefs, often called the rainforests of the sea, cover less than 1% of the world’s surface, but support 25% of all marine life and more than a billion people.

Mary Kay is working with partners like The Nature Conservancy to protect Earth’s most valuable resources. Clean, healthy water isn’t just essential to our business—it’s essential for life everywhere,” added Gibbins.

This year, Mary Kay will also continue to support Texas coastal wetlands, while TNC will continue to work toward its three-year project goals:

  • Identify priority wetland areas for protection and restoration across more than 27,000 kilometers of shoreline along the Gulf of Mexico
  • Produce a Coastal Conservation and Restoration Action Plan for Texas’ three blue carbon ecosystems—mangroves, salt marsh, and seagrass—including mapping areas where we expect wetlands will migrate in the future due to climate change
  • Assess the feasibility of blue carbon markets to support long-term wetland management needs in Texas
  • Identify a dynamic coastal wetland site that can be established as a “living laboratory” to share conservation techniques, explore blue carbon offsets, and highlight the importance of these critical ecosystems.

Over the past 33 years, Mary Kay’s support has extended to hundreds of projects in partnership with TNC, including ocean work and coral reef restoration around the world.

They also point out that thanks to this association, the leadership of women in marine conservation has been elevated through programs that incorporate gender equity in conservation initiatives.

TNC is committed to conserving 4 billion hectares of the ocean by 2030, and we are grateful for support from Mary Kay to help achieve this critical goal. Strong partnerships with governments, non-profits, companies, and local communities are essential to our success,” pointed out Dr. Lizzie Mcleod, TNC’s Global Oceans director.

TNC is a global environmental organization dedicated to preserving the lands and waters on which all life depends.

It works to create innovative and practical solutions to the planet’s most pressing challenges so that nature and people can thrive together.

“We are tackling climate change, conserving lands, waters and oceans at an unprecedented scale, providing food and water sustainably and helping make cities more sustainable,” highlights TNC.

Looking for an Art Excursion in New York This Summer? Here Are Four Perfect Itineraries That Combine Nature and Culture

[ad_1]

This summer, nature is in full bloom at four major art institutions around New York City: the Metropolitan Museum of Art, the Met Cloisters, the New York Botanical Garden, and Storm King Art Center (north of the city). Just as important as the shows themselves are your activities before and after. Here’s our cheat sheet to navigating your way around them as you savor the dual experiences. Don’t forget your walking shoes!

Metropolitan Museum of Art
“Van Gogh’s Cypresses”

Planning a visit to the highly anticipated Vincent van Gogh “Cypresses” exhibition at the Met (through August 27)? You are, of course, going to need your strength. First, duck into Bluestone Lane (1085 Fifth Avenue at 90th Street)—an Upper East Side favorite—for bracingly strong coffee. Placing your order under the grand stone archway of the historic Church of the Heavenly Rest isn’t a shabby way to start your day.

Now that you’re rejuvenated, walk south along iconic Fifth Avenue toward the Met (1000 Fifth Avenue, between 82nd and 83rd Streets), where nearly 40 of the daring Post-Impressionist’s paintings await, including masterpieces like Wheat Field with Cypresses and The Starry Night. It’s Van Gogh’s first exhibition to focus on cypress trees, those enigmatic evergreens that figure prominently in his oeuvre.

After taking in his arboreal brushstrokes, step out the back of the museum for the real thing. Central Park is famed for its idyllic landscapes and sylvan strolls. The Ramble, a short walk west (between 73rd Street and 78th Street), offers 38 acres of winding paths, not to mention excellent birdwatching. The Great Lawn, meanwhile, provides grassy patches to rest your weary feet or roll out a picnic lunch. The lawn also holds any number of summer concerts this summer.

Should all that imbibing of nature inspire quaffing of another kind, trek back toward civilization, across Fifth Avenue, for the quintessential post-Met romp: the Carlyle Hotel. Inside, the historic and luxurious Bemelmans Bar—where whimsical murals by Ludwig Bemelmans, creator of the Madeline children’s books, adorn the walls—offers an array of refreshing beverages, from dirty martinis to Shirley Temples.

Met Cloisters
Garden Tours

Located at 99 Margaret Corbin Drive in Northern Manhattan’s Fort Tryon Park, the Cloisters—governed by the Metropolitan Museum of Art—has been a must-see for locals and visitors since opening to the public in 1938. Open year round with free admission, it was founded by John D. Rockefeller, Jr., reassembled from fragments the oil heir acquired from American artist George Grey Barnard, who in in the early 1900s began collecting medieval art and architectural fragments from European monasteries and churches that were being demolished.

The richness of medieval Europe is on full display. Many of the works are world-famous, like the incredibly preserved late 15th-century Unicorn Tapestries, with their dense, vibrant millefleurs, and the 12th-century Cloisters Cross. Another gem of the collection is the Book of Flower Studies (ca. 1510–20), in which medieval illuminators in Tours, France, made watercolor illustrations of numerous flower species with remarkable attention to detail.

Visitors are also advised to seek out some quality time with the namesake cloisters, meditative gardens located in various corners of the museum; their therapeutic value is the stuff of legend. A horticultural staff maintains the gardens and gives daily educational tours, too.

Fort Tryon Park itself is worth the trip. The space is rich in history, serving as a battleground in the Revolutionary War, and boasts eight miles of pathways, as well as plenty of lawn space for picnics. Heather Garden, Manhattan’s biggest, contains over 500 varieties of plants, while Linden Terrace offers unobstructed and spectacular views of the Hudson River.

 

New York Botanical Garden

Before heading inside the New York Botanical Garden at 2900 Southern Boulevard in the Bronx, it would be wise to make a pitstop at La Masa, a modern Colombian bakery at 726 Lydig Avenue on the garden’s east side. Here you can power up on gourmet empanadas and, of course, perfectly roasted coffee.

Now for the main event, where the contemporary artist Ebony G. Patterson has transformed the gardenone of the largest of its kind in the world, boasting over a million living plants—into a stunning medley of art and nature. Flowers, fabric, glass, and other materials combine to create lush, otherworldly environments.

The sprawling site-specific exhibition (through October 2) is the result of the Jamaican-born artist’s yearlong residency at the garden, making her the first visual artist to embed within the institution. Be sure to check out the Herbarium, where Patterson has installed the centerpiece of the exhibition, a monumental glass and stone peacock.

After a day of soaking in all that art and nature, you don’t even need to leave the garden to revive. Make your way to the northwestern corner to the scenic Hudson Garden Grill, which is conveniently nestled among the 40 acres of the Ross Conifer Arboretum. The menu emphasizes locally sourced recipes and ethically produced ingredients straight from Hudson Valley farms.

Storm King Art Center

Storm King has just opened for the summer season, and not a moment too soon. The 500-acre open-air museum contains perhaps the largest collection of contemporary outdoor sculptures in the U.S.—and it’s located only an hour’s drive north of Manhattan in the Hudson Valley, at 1 Museum Road in New Windsor. Although it was originally devoted to Hudson River School painting, Storm King soon began placing large-scale sculptures directly into its landscape, turning it into a world-class sculpture park. 

This summer, Storm King has added three contemporary sculptors to its roster (through November 13). New York-based Swiss artist Ugo Rondinone has installed the sun (2018) and the moon (2021), two large circular sculptures fashioned out of cast-bronze tree branches. RA Walden, meanwhile, has reimagined the electron configuration of the six most common elements—carbon, hydrogen, nitrogen, oxygen, phosphorus, and sulfur—as crop circles on a hillside. And Beatriz Cortez has sculpted, by hand, volcano-like forms with undulating surfaces that echo the surrounding landscape.

As long as you’re near the art center of Beacon (just across the Hudson River), why not take a small detour to Dia Beacon? Housed in a former Nabisco box-printing factory at 3 Beekman Street, the museum’s collection includes major works by artists—particularly land artists—such as Richard Serra, Nancy Holt, and Robert Smithson. 

Should you need to stay a night or two before heading back to the city, Beacon is the place to do it. Look no further than the Roundhouse Hotel, at 2 East Main Street. The property was originally a textile manufacturer and one of the first factories in Beacon. Its restaurant, too, is a must, inspired by the agricultural richness of the Hudson Valley, highlighting local farms, wineries, and distilleries. Plus, all the tables have waterfall and creek views through floor-to-ceiling windows.

Snapshot: Earth Photo Awards 2023

[ad_1]

Ever since humans began to farm 10,000 years ago, they have altered Earth’s landscape. First in only small, local ways, but as humanity progressed, so too did its influence over nature.

From mining and logging to relocating or eradicating species, our management of the natural world can be seen almost everywhere.

In recent decades the effects of these interventions have been amplified by climate change, as a warming world compounds many of the unintended consequences of our actions.

Earth Photo, a competition run by Forestry England and the Royal Geographical Society, aims to ‘make viewers think differently’, capturing nature, people, place and space, forests, the land and seascapes, and the varied impacts of – and adaptations to – climate change.

More than 1,400 entries have been whittled down to 128 photos and videos, with the winners announced on Thursday, June 22.

From people working in harmony with the landscape and destroying it, to the visual impacts of climate change, this selection of entries highlights the many different forms our relationship with nature can take.

The Bankura district in West Bengal is currently facing a severe drinking water crisis, with villagers struggling to access clean and clear water. Most of the time, they have to collect muddy water from dried river beds and filter it to make it drinkable. This situation highlights the urgent need for sustainable water management practices, conservation of freshwater sources, and equitable distribution of safe and clean drinking water to all people’ (Picture: Sandipani Chattopadhyay)

The Holderness coast located in the north east of England is one of Europe’s fastest eroding coastlines. The devastating consequence of this is villages and land slowly disappearing into the sea. The Lost Villages project explores the constant battle between the North Sea and the mainland, and to document the irreversible change taking place on the ancient coast, formed during the last ice age. Photographer Neil White says: ‘The speed of erosion has increased significantly in the past decade thanks to rising sea levels – linked to climate change. It is estimated that up to 32 villages dating back to Roman times have already been lost.’ (Picture: Neil A White)

Members of a high-angle tree clearing team watch as a helicopter returns with another load of equipment and camping gear as they are deployed to a remote montane watershed that feeds the Theewaterskloof dam in the Western Cape province of South Africa. Photographer Nyani Quarmyne says: ‘Needing wood, colonial settlers introduced pines, eucalyptus and Australian acacia trees to South Africa. Now counted among a number of alien invasive plant species, they are wreaking havoc upon native ecosystems and leading to hotter, more frequent fires. And they are sucking up water. In 2018 Cape Town famously came close to running dry. The Nature Conservancy (TNC) estimates that eliminating ‘aliens’ from the greater metro region’s watersheds will save 55billion litres of water a year by 2025 – two months’ supply for 4.8million people.’ (Picture: Nyani Quarmyne)

They fish individually with basket traps, in pairs with line nets, and spear-fish in small teams – then barbecue their catch over open fires on their wooden boats! Sustainable fishing ensures their community’s livelihood, so they selflessly balance their catch size with the highly variable water levels, caused by heavy monsoons, wet summers, and dry winters. The challenging circumstances and changing climate have forged a people who deeply love and respect Mother Nature. We could learn much from these remarkable, resourceful, and resilient people.’ (Picture: Lee Ju Shen)

Scientists of the Kurchatov nuclear centre, northeast Kazakhstan. In the shooting ranges of Semipalatinsk, in the former Soviet Union, 456 nuclear warheads were tested. The impact of the radiation on the population of the nearby inhabited areas was kept hidden for several decades by the Soviet authorities. The nuclear fallout of the experiments directly affected about 200,000 inhabitants and impacted more than a million people. Photographer Pierpaolo Mittica says: ‘What happened on the Semipalatinsk Polygon is regarded as one of the greatest crimes planned against humanity. The local population was used specifically as guinea pigs to understand the consequences of radiation on people. Today the life for the local people goes on, struggling among this legacy.’ (Picture: Pierpaolo Mittica)

This algae doesn’t exist. Craig Ames used artificial intelligence to create new species based on the cutting-edge work of English botanist and photographer Anna Atkins in the mid-Nineteenth century. Working from a broad sample of the specimens Atkins originally rendered, Ames repurposes their Latin names to create instructional ‘prompts’, which were processed through a text-to-image AI image generator. Revealing the photographic language and aesthetics deriving from the algorithm’s machine learning, the AI was instructed to create photographic representations of the individual specimens. The resulting fabrications were labelled and catalogued to create a new visual taxonomy of simulated algae. Photographer Craig Ames says: ‘The work distorts the boundaries between the real and the artificial, highlighting a growing disconnect between the natural world and the simulated hyperreality that increasingly subsumes it.’ (Picture: Craig Ames)

Sigma 14mm F1.4 DG DN Art review

[ad_1]

 Sigma 14mm F1.4 DG DN Art

Sigma 14mm F1.4 DG DN Art

Building the Sigma 14mm F1.4 DG DN Art was a bold move. There’s already a very good Sigma 14mm F1.8 DG HSM Art lens on the market, which was originally designed for Canon and Nikon DSLRs and subsequently repurposed for Sony and L-mount mirrorless cameras. And if you’re in the Sony camp, there’s also the thoroughly excellent Sony FE 14mm F1.8 G Master lens.

The new Sigma focuses primarily on astrophotography, where the brighter f/1.4 aperture pays dividends. Even so, it’s designed to be a high-performance ultra-wide-angle lens that’s entirely suitable for any scenario from landscapes and cityscapes to weddings and architectural interiors, and any time you simply want an expansive field of view.

Sigma 14mm F1.4 DG DN Art

Surprisingly, the Sigma pretty much matches the two slower f/1.8 lenses for purchase price but, by necessity, has a bigger and weightier build. Indeed, it’s physically wider and 50 per cent longer than Sigma’s DSLR lens. It’s also more than twice the weight of the Sony f/1.8 lens, at 1,170g compared with just 460g. That’s the cost of the extra two-thirds of an f-stop in aperture brightness.

Key features

This Sigma is certainly rich in features. Let’s start with glass. The optical line-up features no less than 19 elements in 15 groups. These include an SLD (Special Low Dispersion) element, three top-grade FLD (‘Fluorite’ Low Dispersion) elements and four aspherical elements. Taking astrophotography very much into account, the overall optical design aims to maximize sharpness across the whole image frame while minimizing sagittal coma flare, so that bright points of light don’t take on blurred or irregular shapes, even towards the edges and corners of the frame.

Sigma 14mm F1.4 DG DN Art

Autofocus is driven by Sigma’s latest High-response Linear Actuator (HLA) breed of motor, which aims to give faster performance for stills and smoother transitions for video, while also being virtually silent in operation. A customizable AF-Lock button is featured on the barrel, as well as a manual focus lock switch, which we’ll come back to later.

As you’d expect, there’s full compatibility for controlling the aperture from the host camera body in PASM shooting modes, but the lens also features an onboard aperture control ring. What’s more, it comes with click steps of one-third f/stop increments and a de-click switch for stepless adjustments when shooting video.

As with most ultra-wide angle lenses, the Sigma has an integral petal-shaped filter that can’t be removed. Not just for shielding the lens from light entering at oblique angles, it also gives physical protection to the protruding front element. At the back end, there’s a gel filter slot built into the mounting plate.

Sigma 14mm F1.4 DG DN Art

A neat touch is that the front lens cap has two built-in compartments for storing gel filters. A smart feature that’s well suited to astrophotography is that the lens has a heat strip retaining mechanism, to keep it in place and avoid any build-up of condensation when night-time temperatures drop.

Build and handling

Build quality feels of an entirely pro-grade standard. The construction includes a brass mounting plate and multiple weather-seals, as well as a fluorine coating on the front element to repel moisture and grease, and to aid easy cleaning. Sigma’s Super Multi Layer Coating is also applied to reduce ghosting and flare.

Weighing 1,170g, the lens doesn’t absolutely need a tripod mounting ring but one is supplied anyway, and comes complete with an Arca-Swiss compatible foot. It’s particularly useful for keeping a good balance when using a tripod or monopod with the camera in portrait orientation mode. If you’re rather not use the mounting ring, it’s easily removable and a rubber band is also supplied which you can fit in its place, to enhance handheld handling, so to speak.

The manual focus locking switch that we mentioned earlier is particularly useful for astrophotography. It enables you to manually focus the lens to infinity and then disengage the focus ring completely, so that the focus setting won’t be affected if you nudge the focus ring accidentally. The same goes for the aperture control ring. Many recent lenses that feature this are notorious for the ring being nudged accidentally from the Auto setting to a narrow aperture, but the Sigma features a locking switch to avoid the problem.

Performance

In our real-world tests, we found that sharpness proved highly impressive across the entire image frame, even when shooting wide-open at f/1.4. That’s no mean feat for such an ultra-wide-angle lens. True to its claims, the Sigma also keeps sagittal coma flare to very low levels, and the same goes for axial chromatic aberration or ‘bokeh fringing’, which is also a challenge for ‘fast’ lenses.

Lateral chromatic aberration is entirely negligible even at the extreme edges and corners of the frame, the lens beating both of the Sigma and Sony 14mm f/1.8 lenses in this respect. It might sound strange to talk about bokeh in a 14mm lens, but the f/1.4 aperture enables quite a tight depth of field for close-ups, thanks to a short minimum focus distance of just 30cm, or about a foot. Bear in mind, that’s measured from the image sensor at the rear of the camera, rather than from the front of the lens, so you really can get in close. Bokeh is nice and smooth wide-open and remains very good when stopping down a little, helped by a particularly well-rounded 11-blade aperture.

Autofocus is super-fast and entirely reliable. All in all, the performance of this Sigma lens is absolutely excellent.

Lab results

We run a range of lab tests under controlled conditions, using the Imatest Master testing suite. Photos of test charts are taken across the range of apertures and zooms (where available), then analyzed for sharpness, distortion and chromatic aberrations.

We use Imatest SFR (spatial frequency response) charts and analysis software to plot lens resolution at the center of the image frame, corners and mid-point distances, across the range of aperture settings and, with zoom lenses, at four different focal lengths. The tests also measure distortion and color fringing (chromatic aberration).

Sharpness:

Sigma 14mm F1.4 DG DN Art lab graph

Levels of sharpness are thoroughly excellent across the whole frame, even when shooting wide-open at f/1.4. Edge-sharpness might not look overly impressive in our lab results but that’s more down to the necessity of having to shoot test charts at extremely close range, due to the extreme field of view of a 14mm lens.

Fringing:

Sigma 14mm F1.4 DG DN Art lab graph

Sigma 14mm F1.4 DG DN Art lab graph

The Sigma does really well to keep both axial and lateral chromatic aberrations to absolutely negligible levels, LCA is virtually non-existent right out to the extreme edges and corners of the image frame, throughout the entire aperture range.

Distortion: -3.62

As with sharpness, close-range lab test results for distortion can make ultra-wide-angle lenses look worse than they really are. In real-world tests, we found the lens produced fairly modest barrel distortion and relied very much less on in-camera correction than many other recent lenses designed for mirrorless cameras.

Verdict

For astrophotography, you need a lens that sucks in much light as possible. As the world’s first ultra-wide-angle 14mm lens with an f/1.4 aperture, this Sigma delivers 58 per cent more light to the camera’s image sensor than an f/1.8 lens. Not just a one-trick pony, it’s also great for shooting landscapes, cityscapes and architectural interiors, giving fabulous image quality backed up by superb handling and excellent build quality. By necessity, it’s a bit of a beast, weighing in at more than a kilogram, but it’s well worth the weight if you feel the need for speed. And the price tag is surprisingly modest.
