Panasonic Corporation traces its origins to 1918, when Kōnosuke Matsushita — then a 23-year-old inspector at the Osaka Electric Light Company — founded the Matsushita Electric Housewares Manufacturing Works in Osaka to produce an improved two-socket electrical attachment plug. The company grew into one of Japan's largest electronics conglomerates across consumer electronics, appliances, automotive components, and precision optical systems. Matsushita Electric was renamed Panasonic Corporation in October 2008 to align the corporate identity with its best-known brand.
Panasonic's involvement in precision optics developed through its broadcast and industrial divisions, which produced Panasonic-branded video cameras and ENG/EFP zoom lenses for professional broadcast use — including the AG-DVX100 (2002), the first 24p mini-DV camcorder. The consumer camera brand Lumix was launched in 2001 with the DMC-F1, a compact that introduced a Leica-certified wide-zoom lens. A formal technical collaboration agreement with Leica Camera AG — established in 2000 and covering optical design, production quality, and performance certification — defined the Lumix product identity through the compact era. Panasonic-designed lenses meeting Leica's certification standards were labeled with Leica DC Vario-Elmarit and Elmar names on compact bodies and with the Leica DG (Digital GRADE) Summilux and Summicron designations on interchangeable-lens systems.
The compact collaboration gave way in 2008 to a more consequential architectural partnership: Panasonic and Olympus jointly announced the Micro Four Thirds System standard, which removed the mirror box from the existing Four Thirds SLR specification and shortened the flange focal distance to 19.25 mm — enabling a generation of compact mirrorless cameras and purpose-designed lenses. The first Micro Four Thirds bodies were the Panasonic DMC-G1 (2008) and the Olympus E-P1 (2009). Panasonic's LUMIX G lens line expanded into a comprehensive Micro Four Thirds ecosystem of primes and zooms, including the co-branded Leica DG Summilux 25 mm f/1.4 ASPH, the Leica DG Summilux 12 mm f/1.4 ASPH, and the LUMIX G Vario 7–14 mm f/4 ASPH ultra-wide.
In September 2018, Panasonic announced the LUMIX S1 and S1R full-frame mirrorless cameras and joined the L-mount Alliance — a three-way interoperability agreement with Leica Camera AG and Sigma Corporation that specified a 51.6 mm mount diameter, 20 mm flange focal distance, and ten-contact electronic interface. The L-mount Alliance opens full lens cross-compatibility among Leica SL, Panasonic LUMIX S, and Sigma fp bodies and lenses. Panasonic's LUMIX S series for the L-mount spans the S PRO 50 mm f/1.4, S PRO 70–200 mm f/2.8 O.I.S., S PRO 16–35 mm f/4, S 85 mm f/1.8, and S 18 mm f/1.8, among others; the compact LUMIX S9 (2024) extended the S system to a smaller prosumer body.
