Sigma 14mm F1.8 DG HSM ART lens review – Space.com

Published

 on


Up until recently, the Sigma 14mm F1.8 DG HSM ART lens could make a very striking claim to be the world’s fastest 14mm prime production lens. Its maximum aperture of f/1.8 makes it a stop faster than Canon’s 14-year-old EF 14mm f/2.8L II USM; and the same goes for Nikon’s 21-year-old AF Nikkor 14mm f/2.8D ED.

Sony’s soon-to-hit-the-shelves FE 14mm F1.8 GM matches the Sigma, aperture-wise, but it’s not available anywhere yet and besides, when it does become available, you’ll only be able to use it with Sony-mount cameras. Sigma’s ultra-wide, ultra-fast astrophotography specialist is available in Canon, Sigma, Sony, Nikon, and L-mounts, making it compatible with a very wide range of cameras.

Essential info:

Type: 14mm prime lens for full-frame and APS-C sensor cameras.

Compatibility: Canon EF, Nikon F-mount, Sony E-mount, L-mount.

Focal range: 14mm fixed focal length.

Aperture range: f/1.8 – f/16.

Thread size: No filter thread.

Weight: 2.58 Ibs

The appeal of the Sigma 14mm F1.8 DG HSM ART lens for astrophotographers is immediately obvious. Its 14mm fixed focal length makes it ultra-wide, if you put much stock in the 500 rule which means you can shoot exposures of up to just under 36 seconds before suffering star trails. The large f/1.8 aperture will also save you a stop of ISO – so if you’re shooting ISO 12,800 on one of Canon or Nikon’s 14mm prime lenses, you’ll only be shooting ISO 6,400 on the Sigma 14mm F1.8 DG HSM ART lens. That’s a significant reduction which in some cases will be the difference between a printable and an unprintable image.

But what is it like to use the Sigma 14mm F1.8 DG HSM ART lens and how does it perform in the field? Perhaps even more importantly, can it justify its $1600 asking price?

Sigma 14mm F1.8 DG HSM ART lens review: Design

  •  2.58 Ibs weight 
  •  No filter thread 
  •  Bulbous front element 

This thing is a lump. Not a very technical description, perhaps, but heft it out of the box and you’ll see what we mean. It’s wide, short, and squat: the Sigma 14mm F1.8 DG HSM ART lens has a large 95mm diameter and is 150mm from front element to mount. It’s heavy as well – 2.58 pounds makes it about twice as heavy as Canon and Nikon’s (slower) 14mm primes. If your chosen star-gazing site is located a decent walk away from your car this is worth bearing in mind – in combination with a full-frame camera, this is a heavy choice of lens.

The Sigma 14mm F1.8 DG HSM ART lens is built of quality materials from front to back, though, so we can forgive the added heft. The slide-off lens cover has a thin strip of fuzzy material inside so the cap can’t slip off in your bag. The lens cover and some of the rest of the lens are made of hardy-feeling plastic; the rear of the lens and the brass mount are made of metal. As is often the case with ultra-wide lenses, the petal hood is permanently attached to the lens – it doesn’t make it much longer and affords a little protection to the front element so in our book, this is a good thing.

There are just a handful of compromises to bear in mind. The first is that the Sigma 14mm F1.8 DG HSM ART lens requires a little more care than bog-standard zooms and even than many normal-focal-length primes. The front element is a spectacular piece of engineering – curving gracefully outwards from the lens body in a gorgeous, bulbous arc – but that does make it a little hard to protect from the elements. Beware of sandy locations, we say. Normal advice for lens elements you want to protect is to bring a UV filter, but you can’t here – the front element of the lens protrudes so far from the body of the lens that there’s no thread in which to mount a filter. Not only does this give you a challenge in terms of protecting the lens but it also means landscape photographers, with their beloved neutral density filters and polarizers, will have a truly awkward time. There’s no option to add a square gelatin filter at the back of the lens.

On the plus side, this is a weather-sealed lens, although how much of a benefit that will be for astrophotographers – who can’t see the stars in inclement weather – is up for debate. If you’re going to shoot other subjects (we took ours storm chasing) it’s a distinct plus.

Otherwise, this is a comparatively simple piece of kit. There’s no stabilizer (astrophotographers will be on tripods anyway), so the only body-mounted control is the auto/manual focus switch, complete with a focus distance window on the top of the lens.

  • Outstanding image quality 
  • Bright maximum aperture 
  • Obedient autofocus

If all the above sounds just a little awkward, that’s because it is. This is a high-performance lens with some specialist applications, and any keen astrophotographer will be delighted to forgo a lens filter as soon as they start using this absolutely spell-binding piece of equipment.

The Sigma 14mm F1.8 DG HSM ART lens is ultra, ultra sharp. For astrophotography you’ll often be using this lens wide open, so we’ll start there: at f/1.8, this lens is a masterpiece. If you’re going somewhere to shoot the heavens, this lens should be either at or near the top of your list. Stars in the center of the frame are super sharp, and it’s only by cropping – heavily – into the corners of our astrophotography images that we were able to begin to discern a little comatic aberration creeping in; what there was was all-but unnoticeable.

Chromatic aberration (purple fringing) is also well controlled. This tends to be more of a problem at large apertures, but in images shot between f/2.8 and f/4, even in high contrast images of snowy scenes, you’ll have to really hunt before you can see it. In terms of creating publishable images that don’t need loads of technical workup before they’re ready, the Sigma 14mm F1.8 DG HSM ART doesn’t miss a trick.

We need to talk about distortion as well – at 14mm we’re well used to seeing lenses with bendy geometry, but the Sigma 14mm F1.8 DG HSM ART lens handles it exceptionally well. It’s a rectilinear lens – that is, not fisheye – and while the images it produces undoubtedly feel “wide”, they don’t distort. This might not be much of a concern with astrophotography, but the fact you can take pictures of people with this lens that don’t make them look distorted and strange is a huge plus, and elevates the Sigma 14mm F1.8 DG HSM ART lens from “astrophotography specialist” to “shoot anything, anywhere”. There is, admittedly, a slight vignetting effect at larger apertures, but it’s well-controlled, less than a stop (to our eye), and easily correctable in software.

Finally, there are a few lovely aesthetic touches that are fun to play with – stop down and you’ll see ultra-sharp star-points to the light sources in your images which make the Sigma 14mm F1.8 DG HSM ART lens a lovely architectural lens as well as an astrophotography specialist.

Should you buy the Sigma 14mm F1.8 DG HSM ART lens?

The Sigma 14mm F1.8 DG HSM ART lens really is a phenomenal lens for night-sky photography. It’s not just that it shoots high-quality, technically excellent images (although it does), it’s not just that its ultra-wide field of view is perfect for incorporating foreground interest into your star shots (although it is), and it’s not just that the ultra-bright aperture allows you to shoot lower ISOs – or longer shutter speeds – than you might otherwise (although it does that too).

The fact that it bundles all those qualities into a portable, sturdy-feeling little package that excels in its niche is really what sells it to us. It isn’t an everyday kind of lens, although with its straight-as-an-arrow geometry you might be surprised how much you actually can use it for. But if you’re after a lens that will get you long shutter speeds without a star tracker, with technically excellent results throughout its aperture range, this is a piece of kit that will serve you well, particularly on those once-in-a-lifetime trips where quality of the results outweighs cost and weight considerations.

If this product isn’t for you

There are some great options out there at the moment for astrophotographers – many of which have been reviewed right here at Space.com.

In particular, we’d suggest thinking carefully about whether 14mm will do everything you need it to, because there are some excellent wide-angle zooms out there with big maximum apertures. Take Sigma’s own 14-24mm F2.8 DG HSM Art ($1,199.00), which is a stop slower in terms of aperture but allows you to go from ultra-wide to merely very-wide angle with its 14-24mm zoom range. Sigma also makes the 20mm F1.4 DG HSM Art ($834), which is a little longer but is even brighter than the 14mm f/1.8.

If you want to stay on-brand, you could look at the Canon RF 15-35mm F2.8L IS USM ($2399). Pretty much as wide as the 14mm (you won’t be able to tell the difference between 14mm and 15mm) and a stop slower, but with a more practical zoom range which makes it more of an all-rounder for those who aren’t single-minded astrophotographers. 

Nikon users might look at the AF-S NIKKOR 14-24mm f/2.8G ED ($1,746), a frankly glorious piece of kit with lots of practicality for night photography. And Sony users should definitely keep an eye out for the arrival of the 14mm f1.8 GM FE.

Montreal palliative care doctor transforms junk into whimsical art – Global News

Published

 on


After more than 30 years of taking care of patients, doctor Michael Dworkind is gaining attention for artistry of a whole other kind.

The palliative care physician, now in semi-retirement, creates works of whimsical art made entirely of junk.

It’s a passion that Dworkind has been quietly expressing for decades. Dworko – as he is known in the art world – has been transforming discarded trash found on the sidewalk into works of art.

“Unfortunately in our Canadian society we throw out so much good stuff,” Dworkind said.  “Garbage day in NDG is my heaven.”

His creations include monstrous faces using shower heads, door stoppers and plungers, and a sculpture of a fiery phoenix with a broom head and construction clamps for a beak.

His art brings out untold reactions from people trying to decipher the piece itself but also the pieces it’s made out of.

“It’s humorous because people say things: ‘this comes from there, that from there; Ahh isn’t that funny.’ That’s the reaction I want.”

Dworkind says his work has no rhyme or reason – the ‘junk’ speaks to him.

“Sometimes I’ll just see something on the curb and want to have it,” Dworkind said.

His art is showcased all over the walls of his NDG home and in devoted rooms as small galleries. Little of his work is seen by the public.

But that has now changed with the latest short film produced by photographer Ezra Soiferman.

“I was blown away and I decided to take out my camera and start making a movie,” Soiferman said.

Titled The Junk On My Roof the film shines a light on Dworkind’s hidden but bright rooftop sculpture garden.

Soiferman says Dworkind is a renaissance man that has many stories already told, none of which have been about his art.

For example, in 1985 he served as a member of the International Physicians for the Prevention of Nuclear War which won a Nobel Peace Prize.

Dworkind is currently the co-founder and medical sirector of Santé Cannabis, the leading education and resource centre for the use of medical cannabis in Quebec.

“When I see another artist who is out there hustling creating things using their voice to express themselves in a unique way I get excited,” Soiferman said.

Soiferman says people are surprised and overjoyed by the five-minute walkthrough film.

Family members of former patients at the Jewish general hospital where Dworkind used to practice have been reaching out, commending the video and the artwork.

Dworkind says he’s humbled by the video and the attention it’s gotten online.

Soiferman says the duo is far from done. They plan to create a second project described as a soup-ed up slide show showcasing art through photo and music focusing on the more than 100 sculptures peppered across Dworkind’s property in the Laurentians.

“That place is like a sculptural Disneyland. It’s wild and whimsical,” Soiferman said.

City of London unveils SITELINES artwork and plaque – london.ca

Published

 on


Today, the City celebrated new public art unveiled downtown. SITELINES is a sculptural canopy created by artist Jyhling Lee, and will be a new landmark inspired by the city’s nickname “Forest City”.

The sculpture embodies a vision of the forest treeline, the city skyline, and the soaring spires found in the area’s heritage architecture, trees and plants. It is an art installation which provides viewers the opportunity to interpret natural and urban surroundings in imaginative ways.

The artwork was funded by Tricar Developments Inc. and installed on public property outside their Azure Condominiums at 505 Talbot Street. This new artwork is owned and will be maintained by the City of London.

“SITELINES is an excellent example of how public and private partnerships are helping to place public art throughout London,” says Mayor Ed Holder. “This art also contributes creatively to the ongoing revitalization of London’s core and is a superb addition to the City’s public arts collection.”

“At Tricar, we are committed to improving and fostering healthy communities on economic, cultural and environmental levels. We strive to enhance the quality of the public realm, promote active lifestyles and develop community pride and a sense of belonging,” says Jen Grozelle, manager of marketing and media at Tricar Developments Inc. “This public art project has been an exciting journey – from the initial artist jury selection process through to seeing the final sculpture beautifully displayed. This sculpture inspires cultural expression on our streets, enhances the quality of life for Azure homeowners and beautifies the neighbourhood.”

SITELINES is located near the northwest corner of Talbot Street and Dufferin Avenue at the widened sidewalk, and offers pedestrians a shady public area to experience this art while underneath the canopy.

SITELINES was created by professional artist, architect and educator Jyhling Lee of figureground studios, who has been involved in a wide range of public art projects across Canada and has been recognized nationally through awards and publications. Lee grew up in Ingersoll, Ontario, and her family has spent the past 20 years in London, operating a food business at the Covent Garden Market for much of their time in the Forest City.

Lee was selected through the City’s Public Art Program process administered by the London Arts Council. For over a decade, the London Arts Council has partnered with the City of London’s Culture Services to help create new opportunities for public art through the Public Art Policy. The London Arts Council administers this program (on behalf of Culture Services) by evaluating sites, convening juries for artist selection and overseeing installation timelines.

Adm. Art McDonald letter to senior military officials ‘shocking,’ says Gen. Eyre – Global News

Published

 on


A letter sent by Adm. Art McDonald to senior military officials claiming he has been exonerated on an allegation of sexual assault and should be immediately reinstated is “shocking,” says Canada’s acting top soldier.

Gen. Wayne Eyre, acting chief of the defence staff, responded to the letter sent by McDonald in his own letter to senior staff, which was shared with Global News. McDonald was placed on indefinite leave by the government and is waging amid an increasingly public battle to return to the top post.

“We must remember that in a democracy the military is subordinate to our duly elected civilian leadership. This fundamental is paramount to our profession. I was asked to act as Chief of the Defence Staff on February 25, and I will continue in that role until told otherwise by our civilian leadership,” wrote Eyre in the letter on Friday.

“To that end, this shocking letter changes nothing with respect to our vital work of defending our nation, changing our culture, and preparing for the threats ahead.”

One defence official told Global News that McDonald neither consulted nor informed Eyre of his plans to send out the contentious letter.

Defence Minister Harjit Sajjan said in a statement to Global News on Friday that the message sent by McDonald “is inappropriate and unacceptable.”

“In Canada, civilians provide necessary oversight of the military and decide who is best suited to lead the armed forces” Sajjan said. “McDonald’s email does not reflect this, nor does it reflect the need to put survivors and victims of sexual misconduct first.”

In the letter obtained by Global News on Thursday, McDonald said he was “quite disappointed that my exoneration has not seen my return to duty” after military police declined to charge the admiral over alleged sexual misconduct in August.

Global News has previously reported the allegation is specifically one of sexual assault.

McDonald also argued his reinstatement is important to avoid “undermining the principles that must be foundational to legitimate cultural change” within the military, citing the need for fairness for both accusers and those accused of wrongdoing.

McDonald denied the allegation against him, and added that media reports were “often replete with hurtful sensationalism, innuendo and inaccurate characterizations.”

Two sources confirmed the letter, addressed to generals and flag officers of the Canadian Forces, was sent by McDonald and bore his signature.

Military and political sources have said the lack of criminal charges against McDonald has not removed concerns about whether he has the moral authority to lead the military.

Global News learned in August that the Canadian Forces National Investigation Service interviewed dozens of people as part of the probe into the allegation, but were unable to determine an agreed-upon set of facts, as many of those interviewed claimed to have been drunk at the time of the alleged sexual assault.

The Department of National Defence said at the time that its investigation “did not reveal evidence to support the laying of charges under either the Code of Service Discipline or the Criminal Code of Canada.”

“Adm. Art McDonald was not exonerated by the military police,” said Charlotte Duval-Lantoine, a fellow with the Canadian Global Affairs Institute specializing in military culture.

“They could not meet the burden of proof to charge Art McDonald. That doesn’t mean that the allegations were false.

“It doesn’t mean that the victim was lying … so he cannot say that he was exonerated.”

Duval-Lantoine said she was “appalled” to hear of McDonald’s letter and noted it raises fresh questions around whether he holds the moral authority to govern the Canadian military.

“He’s determining for himself that he has the moral authority to gain back to the job of chief of the defense staff,” Duval-Lantoine explained.

“What he doesn’t realize is that it is not his decision to make. He’s not the one who needs to determine whether he has a moral authority. It is up to the government, and I would also argue that it is the determination of service members that would be under his command.”

IN HER WORDS: The woman behind McDonald allegation tells her story

Retired Lt.-Gen. Mike Day, former commander of Canada’s special forces, expressed similar concerns at the letter in a blog post on Friday as well, noting he and others are feeling “horror” at what is unfolding.

“Contrary to the Admiral’s claim and the start point of his argument, a failure to press charges, for whatever reason is not an exoneration, neither in form nor function. A decision not to proceed based on insufficient evidence neither exonerates nor condemns,” Day wrote.

“Exoneration can only come from those who govern the Admiral (ie MND / PM).”

Day noted that the position of chief of the defence staff is one that serves at the pleasure of the government, and said McDonald’s decision to pursue his campaign for reinstatement so publicly indicates one of several “concerning” possibilities: either he doesn’t understand how the process actually works, or he is “not targeting his return but rather any negotiations that might inform his release.”

“If the first instance such ignorance is disqualifying,” Day explained. “In the second there is a demonstration of a willingness to ignore the impact on Lt(N) [Heather] Macdonald as well as to continue to negatively impact the morale of the CAF for personal gain: This too is disqualifying.”

Macdonald told Global News previously that the decision by military police not to pursue any charges against McDonald left her feeling like she’d been “punched in the stomach.”

“I am not surprised as this was exactly why I was reluctant to come forward and why most survivors don’t come forward. It’s not worth it. I feel a little like I’ve gone through hell for nothing,” said Macdonald, a navy combat systems engineer who has served for 16 years.

Since McDonald’s letter became public, multiple women officers who have been victims of sexual misconduct told Global News they were deeply concerned by the tone of the letter and the message it sends to those who may want to come forward.

Former Supreme Court Justice Morris Fish warned in June that it is “legally impossible” to charge senior military officials of McDonald’s rank under the military justice system.

Global News confirmed last month this finding had played a direct role in the decision by military police not to lay charges under the military system during a probe into McDonald’s predecessor.

Exclusive: Gen. Jonathan Vance won’t face any military service charges – Sep 15, 2021

Retired Gen. Jonathan Vance is facing allegations of inappropriate behaviour from two female subordinates, which were first reported on by Global News on Feb. 2.

He denies all allegations of inappropriate behaviour.

Gen. Jonathan Vance charged with obstruction of justice after military investigation

Military police opened an investigation into the allegations shortly afterward and in July, charged him with one count of obstruction of justice for alleged conduct during the course of their investigation.

The Canadian Forces National Investigation Service handed the case over to the civilian criminal court system, but opted not to pursue any charges against Vance on the allegations of sexual misconduct through the military court system, citing the Fish report.

Since the allegations against Vance emerged, multiple senior military leaders have been removed from their positions or investigated for allegations of sexual misconduct, sparking what experts have called an institutional “crisis” and a reckoning for the Canadian Forces.

Former Supreme Court justice Louise Arbour was appointed by the government in April to lead an external, independent review tasked with providing recommendations on how best to create an independent reporting system for military sexual misconduct.

Global News has confirmed Arbour does not plan at this stage to issue any interim recommendations.

Here’s what you need to know about the military sexual misconduct crisis

During the last session of Parliament, Liberal Anita Vandenbeld — who was parliamentary secretary to the defence minister — had said Arbour would be issuing interim recommendations so the government could implement them quickly.

“Throughout the process, she will provide interim recommendations that we can implement right away,” Vandenbeld said on May 10.

While Arbour’s appointment was announced in April, her contract to begin the review did not kick in until May 21, and she has 12 months from that date to complete her review, according to its terms of reference.

Last week, Prime Minister Justin Trudeau said the military “still doesn’t get that survivors need to be at the centre and the unique priority of everything in regards to sexual misconduct and harassment in the military.”

“This is, again, a reminder of just how much work there is to do.”

When asked by Global News whether work on creating an independent reporting system for military sexual misconduct will begin this fall or winter, given Arbour’s recommendations aren’t due until next year, a spokesperson for the Prime Minister’s Office offered a brief response.

“I’ll refer you to DND on this matter.”
