SIGMA Corporation of America is the US subsidiary of SIGMA Corporation, a family-owned manufacturer of lenses, cameras and photo accessories. Since 1961, SIGMA has worked towards a single, simple goal: to imagine and develop the technologies that will allow the attainment of the perfect image. It's a commitment we've made, and honored since day one. It's evident in our collaborative design process that unites R&D, manufacturing, marketing, sales, and service. It's evident in our standards — above and beyond industry norms — requiring 100% of our lenses be analyzed by our proprietary ultra-high definition sensors and approved before leaving our factory. And its evident in our final products, built with premium materials, and known worldwide for quality and performance. Photography is all we do. And it's all we've done. So you can rest assured that it's something we know extensively and care deeply about. For decades, the pros have come to rely on SIGMA for reliability, selection, and innovation. They've shown their support by always coming back. They know they can trust their art to us. And so can you. Your equipment is an extension of you. You need it to deliver consistently, and flawlessly. And that is a responsibility we take very seriously. We want to deliver the technology that allows our customers to take their photography wherever inspiration takes them. You have a vision. We've made it our mission.
