In the history of photography, Japan occupies a singular place. Most of the companies that shaped the modern camera industry—Canon, Nikon, Sony, Minolta, Pentax, Sigma—are Japanese. Yet among them, Sigma stands apart. Not because it is the largest, nor the most powerful, but because it may be the most Japanese of all: a family-owned company born directly from postwar devastation, shaped by regional identity, and guided by an unusually stubborn belief in independence.
Before the Second World War, photography belonged to Germany. Leica, Contax, Zeiss defined optical excellence. Japan was still learning, observing from the margins. Then the war ended, and the country was left in ruins. “Over 95% of Tokyo was burned down,” recalls Kazuto Yamaki, CEO of Sigma. “Japanese houses were made of wood and paper. Everything was destroyed.”
Reconstruction was not simply a matter of rebuilding cities. It required a complete redirection of knowledge. Military production was banned. Engineers trained for war suddenly had no place to apply their expertise. “Very talented engineers had to change their jobs,” Yamaki explains. “They started working in civilian industries—optics, cameras, trains. We had nothing. So we had to build everything from scratch.”
Sigma emerged from that void. The company was founded in 1961 by Michihiro Yamaki, Kazuto Yamaki’s father, but not as the result of a grand entrepreneurial plan. Michihiro Yamaki came from a very poor family. As a student of electronics, he worked part-time at a small optics company assembling binoculars. An older craftsman taught him how to align prisms precisely between lenses—a meticulous, repetitive task. He was paid by the number of units he completed. “According to him, he earned very good money,” Yamaki recalls. “Almost the same as a manager in a big company.”
That experience shaped his path. After graduating, Michihiro Yamaki chose optics over stability. Japan’s optical industry was expanding rapidly. Nikon and Canon were gaining international recognition, and dozens of smaller companies were emerging around them. Yamaki joined one of these firms and, at just 27, became a corporate executive. Then, suddenly, the company collapsed.
“According to my mother,” Kazuto Yamaki says, carefully, “the owner disappeared one day with the company money and his mistress.” Orders stopped. Salaries could not be paid. As one of the executives, Michihiro Yamaki was responsible for closing the office. That was when suppliers approached him and asked him to continue the business. “That is why Sigma started,” Yamaki says. “Not because of ambition. Because people asked him to.”
Sigma began in a rented house in central Tokyo. There was no factory, no long-term plan. At the time, this was not unusual. The surrounding districts—Itabashi, Ōta—were dense with parts suppliers working for Nikon, Pentax, and Canon. “It was like Shenzhen today,” Yamaki says. “If you had a design, suppliers could make the parts.”
Seven years later, his father made a decisive choice. He wanted to control quality, not depend on suppliers. Sigma moved to the outskirts of Tokyo and built a five-story building. The lower floors housed offices and factory space. The top floor was the family home. “That was 1968,” Yamaki says. “The year I was born.”
He grew up inside the company. Literally. “When I was a boy, I knew everyone,” he recalls. “Everyone’s name. Everyone’s face.” His mother worked as accounting manager. Employees ate together. Problems were discussed at home. “I understood what was happening in the company without being told,” Yamaki says.
From the beginning, Michihiro Yamaki refused to become an anonymous supplier. Many lens manufacturers survived by producing OEM products for larger brands. Sigma did not. “If you are just a supplier,” Yamaki explains, “you cannot control the price.” His father wanted independence, visibility, and a direct relationship with photographers. He built the Sigma brand himself, traveling through Europe and the United States with lenses in his bag, visiting camera shops one by one. That decision—brand over anonymity, independence over safety—explains why Sigma still exists today.
Affordable and qualitative products
Sigma’s identity was forged through lenses. Long before cameras, before branding, before visibility, there was optics. Michihiro Yamaki began with binoculars and teleconverters, solving practical problems rather than chasing prestige. One of Sigma’s first successful products was a rear-mounted teleconverter that worked across multiple camera systems—an unusual idea at the time. “He always tried to find what was missing,” explains Akinobu Saijo, from International Sales. “Something useful. Something no one else was doing.”
This approach placed Sigma on a different path from the major camera manufacturers. Canon and Nikon built closed ecosystems. Sigma built bridges. It produced lenses compatible with mounts it did not own, serving photographers regardless of brand loyalty. Over time, this made Sigma the world’s largest independent lens manufacturer.
Sigma’s lens catalog grew steadily, not through spectacle but through accumulation. Ultra-wide zooms, fast primes, macro lenses, super-telephotos—Sigma explored corners of optical design that larger manufacturers often avoided. Some lenses became milestones: the 12–24mm ultra-wide zoom, the 35mm f/1.4 Art lens that redefined expectations for third-party optics, or the company’s long-standing commitment to extreme focal lengths. “We don’t always try to make what is popular,” Saijo says. “We try to make what is necessary.”
Quality, at Sigma, is inseparable from place. Today, nearly all production happens in Aizu, Fukushima Prefecture. The choice is deliberate. “The environment matters,” Saijo explains. “The people living there are serious. Focused. It’s good for precision work.” The region’s climate, water quality, and remoteness all play a role in manufacturing consistency.
There is also history in the ground. Aizu was the site of the final battles of the 19th century Boshin War, where samurai forces fought until the end against imperial troops. “They did not surrender,” Saijo says. “That spirit remains.”
For Kazuto Yamaki, Aizu is not simply a factory location. It is a responsibility. “If we move production overseas,” he says, “what happens to the people there?” Sigma employs more than 2,100 people worldwide, most of them engineers. Around 90% of the workforce is dedicated to engineering and manufacturing. The company follows what it calls a “small office, big factory” philosophy: minimal corporate structure, maximum investment in making things.
Lens quality, in this context, is not marketing language. It is control. Sigma keeps production in-house to oversee every step: materials, tolerances, assembly, inspection. “If you outsource everything,” Yamaki says, “you don’t really know the quality.”
This insistence on control has costs. Manufacturing in Japan is expensive. Margins are thinner. Growth is slower. But Sigma has accepted those limits. “Photography is a happy business,” Yamaki says. “It should not be only about money.”
Designed for the right photographers
If Sigma’s lenses have long been present on the market, their meaning has shifted over time. For decades, the company’s optics circulated quietly, often chosen for pragmatic reasons: compatibility, availability, price. What changed in recent years, according to Saki Crowne, from Global Marketing Division, is not the lenses themselves, but the way Sigma chose to speak about them.
“For a long time, Sigma was perceived as ‘the same but cheaper,’” she explains. “But the quality was already there. We just didn’t communicate it clearly.” This gap between substance and perception became increasingly visible as Sigma’s engineering ambitions grew. Internally, nothing had changed. Externally, expectations had.
Sigma’s lens families — Art, Contemporary, and Sports — were conceived as a way to clarify intent rather than segment markets artificially. Each line reflects a different relationship to photography: precision and expression for Art, portability and balance for Contemporary, endurance and reach for Sports. But none of them were designed as lifestyle products. “We don’t design lenses to follow trends,” Akinobu Saijo says. “We design them because there is a real photographic need.”
That philosophy applies across markets. Sigma’s lenses are sold globally, through subsidiaries and distributors, in regions with vastly different photographic cultures. “The needs in Europe, the United States, or Asia are not the same,” Saijo explains. “But our approach is consistent.” Sigma does not localize its products to chase volume. Instead, it relies on a stable core identity, trusting photographers to recognize it.
This consistency is also visible in what Sigma refuses to do. The company does not release products on a fixed annual cycle. It does not flood the market with incremental updates. “We don’t want to make products just because we have to,” Saijo says. “If there is no strong reason, we wait.”
For Saki Crowne, this restraint is central to Sigma’s current moment. The company’s recent visual identity update, often interpreted as a rebranding, was never meant to signal reinvention. “We are not changing who we are,” she insists. “We are simply aligning how we look with what we have always been.”
That alignment required confidence. For years, Sigma avoided positioning itself as premium, even when its manufacturing standards justified it. “We never wanted to be seen as a luxury brand,” Crowne says. “Luxury is about image. We are about making.” The distinction matters. Sigma’s ambition is not to compete with fashion houses or status symbols, but to claim legitimacy based on engineering and durability.
This approach has consequences. Sigma’s products are not always immediately understood. Some lenses are heavy. Some are highly specialized. Some address narrow use cases. But that, for Saijo, is precisely the point. “We don’t want everyone to buy our products,” he says. “We want the right people to buy them.”
In that sense, Sigma’s lenses function as long-term objects rather than consumables. They are designed to last, to be repaired, to remain relevant across camera generations. This philosophy, deeply tied to manufacturing everything in Aizu, reinforces a slower relationship to photography — one based on commitment rather than novelty.
A camera like no other
For most of its history, Sigma remained a lens company. Its first camera appeared in 1976, but bodies were never central. That is changing now, carefully and without spectacle.
A new camera, the Sigma BF arrived in early 2025, alongside a broader visual identity update. To outsiders, it looked like a transformation. Inside the company, it felt more like a revelation. “People think Sigma is changing,” says Saki Crowne. “But the quality has always been there. We are just showing it now.”
Machined from a single block of aluminum, the BF is deliberately minimal. Its interface avoids complexity. Its production is slow. Each camera takes hours to make. Volumes are limited. “We are not trying to scale fast,” Crowne explains. “We are trying to do it right.”
For Kazuto Yamaki, cameras were always part of his father’s dream. “He wanted to be a camera manufacturer,” he says. But there was also fear. If camera makers stopped allowing third-party lenses, Sigma’s survival would be threatened. Becoming a camera maker was not only a dream—it was insurance.
Even today, the transition is difficult. “To be honest, we are still losing money on cameras,” Kazuto Yamaki admits. “Lens business is more profitable.” But Sigma is not chasing volume. “If we make a ‘me too’ camera,” he says, “why would anyone buy it?” The BF is not meant to dominate the market. It is meant to express continuity. “It looks like a transition,” Yamaki says. “But for us, it is the same philosophy.”
Sigma remains family-owned. It remains independent. It remains rooted in Aizu, in optics, in memory. It is also a company that supports photographic creation and artists by funding exhibitions such as the one in Arles every year, or through its partnership with the annual Kyotographie festival, the most important one in Japan. In an industry driven by speed and scale, Sigma moves slowly, deliberately, carrying with it the weight of a family story that began in poverty, survived collapse, and grew—floor by floor—into a company that still believes in making things with care.
