There’s a reason why SIGMA continues to insist on the very highest quality in its product manufacturing: our love of photography is second to none. We deeply appreciate the photographer’s desire to record and express—the passion of the photographer. We understand the need to capture the moment that gives rise to a unique work of art. Our endless passion for photography spurs us on to the kind of technical innovation that raises picture quality and performance, and it keeps us looking for new ways to facilitate artistic expression.
At our Aizu factory, integrated production embraces everything from molds to parts
SIGMA’s ability to coordinate things smoothly on the spot is largely thanks to our unique, vertically integrated production system. Apart from a handful of processes, everything is done in house. This includes grinding lenses, molding plastic parts, painting, mounting substrates, assembly, manufacturing screws and other parts, and machining molds. All our interchangeable lenses, cameras and strobes are also produced at our Aizu factory with this integrated system. With production lines that can be flexibly realigned according to a meticulous production plan and easily accommodate high-mix small-lot production, the manufacturing that takes place at Aizu is SIGMA’s greatest asset.
