Sekonic Corporation Japan provides the widest range of light measurement devices for photographers around the world.

Established in June 1951 as Seiko Electric Industries Co., Ltd., the first Sekonic brand exposure meter introduced was the revolutionary Sekonic P-1. 

Over the years, worldwide demand for exposure meters resulted in growth and the construction of a new factory in June of 1959. 

Through the years Sekonic meters became so well recognized that in February 1984 the Sekonic Digipro X-1 and L-518 meters were taken into space on the NASA Space Shuttle. 

Today Sekonic continues to produce and develop meters for every aspect of photography, serving the film, video, cinematography, and digital photography markets.
