An optical-instrument company is founded.
Small cameras, large ideas
Olympus kept asking how much camera a photographer really needed
Olympus began in 1919 as an optical and microscope maker, then entered cameras with a compact 35mm rangefinder. Its camera designers became known for resisting bulk. The PEN cut frame size in half; the Pen F made a half-frame SLR; the OM system shrank the 35mm SLR without making it feel like a toy.
That pursuit of portability was not simply miniaturization. Olympus worked to make cameras quieter, more comfortable and more likely to come along. Its long optical history connected Zuiko lenses, medical instruments and cameras through an unusually broad engineering culture.

1919–1963 · Compactness as a design principle
Yoshihisa Maitani and the PEN idea
Olympus entered the camera market in the 1930s, but its most influential design era began with the PEN in 1959. Designer Yoshihisa Maitani wanted a genuinely useful camera that could be carried every day. Half-frame photography doubled the number of exposures on a roll and enabled a small, simple body. The PEN series became a commercial success and a statement of industrial design.
Maitani pushed the idea further with the Pen F, introduced in 1963: a half-frame SLR with a distinctive rotary shutter and a compact optical path. Olympus did not merely shrink a conventional camera; it redesigned the mechanisms to make the reduced size work.

1972 onward · The OM system
The OM-1 made a compact SLR feel complete
The OM-1, first introduced as the M-1 in 1972, was built around a remarkably compact body, quiet shutter and a wide accessory system. Maitani’s design team looked closely at what photographers carried and how controls met the hand. A smaller camera could reduce fatigue on a long assignment, but the important achievement was that it still felt dependable and serious.
Olympus went on to develop TTL flash metering, sophisticated exposure control and compact professional bodies. The OM system’s influence lives in a way of designing around the photographer’s body and attention. In 2021 Olympus transferred its imaging business to a new company, OM Digital Solutions, which continues the photographic line under OM System.

Small cameras, big ideas
Olympus began as an optical-instrument company in 1919, and the camera division became known for making a lot of photographic ability fit into a small space. The most important person in that story is designer Yoshihisa Maitani. He believed a camera should go where people went, rather than ask them to plan their day around carrying it. The 1959 PEN used half-frame film, so a standard 36-exposure roll could make 72 pictures. That was a practical saving, not a gimmick. The PEN F later turned the idea into a small interchangeable-lens SLR with a distinctive rotary shutter. The Trip 35 brought another kind of freedom: a compact full-frame camera ready for travel and ordinary family life.
The OM system took Maitani’s compactness seriously even for professional photographers. The OM-1 gave them a smaller, quieter SLR that could be carried all day; it did not ask professionals to choose between portability and a complete lens system. The XA tucked a protected lens and rangefinder into a pocketable body. Those cameras succeeded because their size solved a real annoyance, while the controls and lenses still felt thoughtfully made. Olympus also made microscopes and medical equipment, and that optical experience fed its camera work. These models were not just “small Olympus cameras”; they changed expectations about how much equipment a photographer needed to bring along.
Olympus itself remained a strong medical-technology company, but its imaging division faced long-term pressure from smartphones, falling compact-camera sales and the rising cost of digital development. The company reported operating losses for three consecutive years through March 2020, then agreed to transfer the imaging business to Japan Industrial Partners. The transfer completed on 1 January 2021; OM Digital Solutions became the new home for the camera line. This was not corporate bankruptcy. It was a decision to separate a beloved but difficult business from Olympus’s larger medical focus. The PEN and OM names continue under a new company, a reminder that a product heritage can survive even when the corporation that nurtured it changes course.
